Topaz Gigapixel is the strongest starting point for serious photo enlargement, while Upscayl is the best free local option. Adobe users may prefer Photoshop or Lightroom, browser users can choose Let’s Enhance or Topaz Image Web, and Bigjpg or Waifu2x are better suited to anime and line art.
There is no universal winner. The right AI image upscaler depends on your source image, target size, privacy requirements, workflow, and budget.

What AI image upscaling actually does
AI upscaling enlarges an image while estimating plausible edges, textures, patterns, and facial details. It does not recover a guaranteed original hidden inside a small file. It may reconstruct useful detail, but it can also smooth genuine detail or invent hair, skin texture, lettering, and object edges.
Upscaling increases pixel dimensions. Enhancement improves apparent clarity, color, noise, or sharpness. Restoration repairs damage such as scratches, blur, and compression. Generative enhancement may invent detail more aggressively. For historical, legal, journalistic, or documentary images, treat the result as an interpretation rather than recovered truth.

The 18 best AI image upscaler tools
1. Topaz Gigapixel — best dedicated desktop upscaler
Topaz Gigapixel is the best first choice for photographers, printmakers, and anyone who needs substantial enlargement with dedicated controls. Topaz advertises enlargement up to 16× and its product page showed a $99 price signal when captured. Treat both limits and price as changeable. Its local workflow is also attractive for private images and large batches.
Best for: large prints, photographs, and controlled desktop processing. Weakness: it is overkill for a single casual enlargement and requires a capable computer.
2. Topaz Photo — best for upscale-plus-restoration work
Topaz Photo is more appropriate than a pure upscaler when an image also needs denoising, sharpening, face repair, or broader restoration. Use it for noisy or damaged photographs; for a clean, already-sharp image, its extra tools may be unnecessary. See Topaz’s current product options for pricing and licensing.
3. Topaz Image Web — best premium browser option
Topaz Image Web brings premium cloud models to a browser without requiring installation. It suits occasional users and computers that cannot run desktop models. The trade-off is uploading the image and dealing with changing plans, credits, and output limits. A comparison captured plans beginning around $12 per month, but verify current terms.
Rank #2
- Dock Photo Printer: The KODAK Dock Plus is a home photo printer that produces high-quality 4x6” prints directly from compatible smartphones. Featuring an integrated docking station, users can place their phone on the printer for better connection while simultaneously charging the device during printing.
- Genuine 4PASS dye sublimation printing: Each photo is produced in three color layers and finished with a clear protective lamination layer. In approximately 55 seconds, you receive a smooth, detailed print designed to resist fingerprints, water, and fading for long-lasting quality.
- Easy to Use: Print photos quickly without complicated setup or technical steps. Simply power on, connect wireless bluetooth, and start printing within seconds. The Dock Plus is built for straightforward operation, making it ideal for first time users and everyday photo printing.
- Home Printing Station: Designed for stable desktop use, this dock photo printer connects to a power outlet for consistent performance and larger 4x6” prints. Ideal for home printing, photo albums, framing, family events, and everyday picture printing.
- KODAK Photo Printer APP: Featuring integrated Bluetooth connectivity, this portable printer connects to compatible iOS and Android devices through the KODAK Photo Printer app. Edit, crop, and customize your photos before printing for creative results.
4. Photoshop Generative Upscale — best for Photoshop users
Photoshop is practical when enlargement is only one step in a larger editing workflow. Adobe documents Firefly Upscaler and Topaz Gigapixel as selectable models in Generative Upscale, with model and resolution limits that depend on the feature version and plan. Read Adobe’s documentation before relying on a specific model or maximum size.
5. Lightroom and Camera Raw Super Resolution — best for RAW photographers
Lightroom and Camera Raw are convenient for photographers who already organize and edit RAW files in Adobe’s ecosystem. Super Resolution keeps enlargement inside the catalog and development workflow, although it provides less specialist control than a dedicated application. Adobe’s current FAQ explains feature availability.
6. Let’s Enhance — best for browser batch and print preparation
Let’s Enhance is a strong browser choice for batch work and print-oriented output. Its comparison coverage highlights print presets, DPI controls, and high-resolution processing. It uses a credit or subscription model, so calculate the cost for your actual image volume rather than judging only the entry price. See Let’s Enhance’s comparison page.
7. Upscayl — best free local option
Upscayl is free, open-source, and processes images locally. It is a compelling choice for private family photos, confidential client work, and users who do not want subscriptions. Current comparison coverage describes good edge and lettering results, with less refined micro-texture than premium tools. Performance depends on your hardware.
8. VanceAI — best broad browser enhancement suite
VanceAI combines upscaling with denoising, sharpening, and other image-specific models. It is useful when one image needs several kinds of enhancement, but aggressive settings can produce an over-processed appearance. Credits, watermarks, and export rules vary, so inspect the final-download terms.
9. Remini — best quick mobile face enhancement
Remini is convenient for portrait and face enhancement on a phone. It is not the safest choice when historical accuracy matters: face models can smooth skin, alter features, or create plausible details that were never visible in the source. Expect subscription prompts and possible watermarks.

10. Icons8 Smart Upscaler — best for batch and API workflows
Icons8 is aimed at design teams, ecommerce users, and developers. Its tool advertises JPG, PNG, and WebP support, batch uploads of up to 500 images, and output up to 7680×7680 pixels. Confirm current limits and pricing on the tool page, pricing page, and API documentation. Icons8 says uploaded images are retained for history and redownloads and are not used for machine learning or shared publicly; check its current privacy terms before uploading sensitive files.
11. Fotor AI Upscaler — best for casual editing
Fotor suits users who want enlargement alongside templates, retouching, and social-media editing. It is convenient rather than highly specialized. Check whether full-resolution export, watermarks, and commercial use differ between free and paid tiers on its AI upscaler page.
12. HitPaw FotorPea — best desktop all-in-one candidate
FotorPea combines upscaling, denoising, sharpening, and face or general image enhancement in a desktop package. It may be useful for damaged photos, but subscription pricing and feature availability should be checked on the official product page.
13. ON1 Resize AI — best print-focused alternative candidate
ON1 Resize AI is designed around print preparation, resizing controls, and photographer workflows, including plugin use. It deserves consideration when layout and physical output matter as much as enlargement. Verify the current model quality, license type, and upgrade policy on ON1’s product page.
14. Aiarty Image Enhancer — best local alternative candidate
Aiarty offers desktop enhancement modes for photographs, anime, and general images. Local processing can suit privacy-sensitive work, but quality claims, hardware requirements, and license terms should be checked directly at Aiarty’s official page.
15. Bigjpg — best for anime and illustrations
Bigjpg is better matched to anime, line art, and flat-color illustrations than to natural photographic texture. It can preserve clean outlines where photography-oriented models may add unwanted texture. It is a poor fit for serious portrait restoration or documentary photographs.

16. Waifu2x — best lightweight line-art option
Waifu2x remains useful for simple anime and illustration enlargement with noise reduction. Implementations differ, and its controls are limited compared with modern professional applications. Use it for artwork rather than RAW photography, complex restoration, or production catalogs.
17. ImgLarger — best simple browser suite candidate
ImgLarger combines upscaling with other AI image tools and may suit quick browser edits. Before choosing it for production, verify current free limits, output dimensions, privacy terms, signup requirements, and watermark rules.
18. ImgUpscaler — best for a quick one-off enlargement
ImgUpscaler is designed for low-friction browser enlargement. It is convenient when you need a simple result without installing software, but current free credits, output limits, and account requirements should be confirmed before processing a batch.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to choose by image type
Old family photographs
Use a restoration workflow, not enlargement alone: denoise, reduce blur, remove scratches and dust, correct contrast, restore faces cautiously, upscale, then optionally colorize. Topaz Photo, Photoshop, Remini, FotorPea, and VanceAI are more relevant than a basic enlarger. Keep the untouched scan and label the enhanced file as AI-processed.
Printing
Calculate the pixel requirement:
Required pixels = print size in inches × target PPIFor example, 8×10 inches at 300 PPI requires 2400×3000 pixels; 16×20 at 200 PPI requires 3200×4000; and 24×36 at 150 PPI requires 3600×5400. Large wall art is often viewed from farther away, so 300 PPI is not mandatory for every print. Topaz Gigapixel and ON1 Resize AI suit print workflows, while Let’s Enhance emphasizes print presets and DPI controls.
Ecommerce
Prioritize batch consistency, product-edge preservation, packaging-label accuracy, transparent PNG support, API access, commercial licensing, predictable cost, and color consistency. Icons8 and Cloudinary are relevant candidates, but inspect several products from the same catalog before automating anything.

Faces
Compare eyes, teeth, hairlines, glasses, earrings, skin texture, and small faces in group photographs. A face model can make a portrait more attractive while making it less faithful to the person. For archival or evidentiary use, prefer restrained enlargement and manual retouching.
Text, screenshots, and logos
AI models often turn small lettering into plausible but incorrect characters. For important labels, interfaces, logos, and documents, use OCR, vector recreation, or manual redrawing. Never assume that a sharper character is a correct character.
Local versus cloud upscaling
Local tools keep files on your computer, avoid upload dependency, and can be economical for large batches, but they require installation and suitable hardware. Cloud tools are easier on low-powered devices and convenient for occasional work, but involve uploads, credits, queues, subscriptions, and retention policies.
Use a local tool such as Upscayl, Topaz Gigapixel, ON1 Resize AI, or Aiarty for medical images, identity documents, confidential prototypes, NDA-covered client work, or poor internet connections. A cloud service may be fine for ordinary personal images after you review its privacy and deletion policy.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsA practical workflow
- Preserve the original file and make a working copy.
- Crop, straighten, and correct exposure or white balance first.
- Remove severe noise or compression without destroying texture.
- Start with 2× enlargement; use 4× or more only when necessary.
- Select a model for the image type: photo, face, text, art, or general.
- Preview difficult areas at 100% and 200%, including faces, lettering, foliage, and repeating patterns.
- Reduce sharpening if you see halos, ringing, waxy skin, or false texture.
- Correct faces and text manually where accuracy matters.
- Export in the required format and color profile, then compare at the intended screen or print size.
- For archival work, retain the original and identify the output as AI-enhanced.
Do not assume that two moderate passes are always better than one larger pass. Repeated processing can compound artifacts, so compare both workflows on a copy.
What to check before paying
- Is processing local, cloud-based, or hybrid?
- Does “free” include a full-resolution, watermark-free download?
- Are there daily, monthly, file-size, queue, or fair-use limits?
- Does the plan permit commercial use?
- Are pricing and credits shown for your country and billing interval?
- Does it preserve transparency, ICC profiles, metadata, RAW files, and 16-bit output if needed?
- Can it process your required batch size consistently?
- What happens to uploaded images, and how long are they retained?
Bottom line
Choose Topaz Gigapixel for demanding desktop enlargement, Upscayl for free local processing, Photoshop or Lightroom if you already use Adobe, Let’s Enhance or Topaz Image Web for browser convenience, Icons8 or Cloudinary for production pipelines, and Bigjpg or Waifu2x for anime and line art. Start at 2×, inspect for invented detail, and choose faithfulness over artificial sharpness whenever the image’s accuracy matters.
