Best AI Image Upscaler 2026: 10 Tools Compared

The best AI image upscaler in 2026 depends on what you are enlarging. Topaz Gigapixel is the reference desktop app for photographers. Magnific is the pick for creative upscales that invent rich new detail. Upscayl is the best free, open-source option if you have a decent computer, and Let’s Enhance is a simple browser choice for print sizes. VdoBloom puts Topaz Wonder 3.5 (2× or 4×, up to 100 megapixels, from 4 credits), Riverflow 2.0 Pro (18 credits at 2K, 27 at 4K) and Riverflow 2.0 Fast (10 credits at 2K) in one browser tool, with 10 free credits at sign-up and no subscription to keep. A 1920 × 1080 photo to 4K UHD costs 7 credits.

Disclosure: VdoBloom is our product. We compared these upscalers on their published features, maximum sizes and plan types, not on our own scored tests of each tool, so there are no invented ratings here. Where another tool is the better pick we say so. Plans and free tiers change often; check each vendor’s own pricing page before you buy.

Quick facts

Best for photographers: Topaz Gigapixel (desktop).
Best for creative, detail-adding upscales: Magnific.
Best free upscaler: Upscayl, open source, runs on your own computer.

How we compared

We chose the upscalers people ask about most, plus a free option and two that live inside popular editors, and compared them on published features. We did not run our own scored tests of the other tools. The criteria:

Maximum output. Scale factors (2×, 4× and more) and the largest result in pixels or megapixels.
Faithful vs creative. Does it sharpen what is there, or invent new detail? Both have uses.
Controls. Strength or creativity sliders, face recovery, denoise.
Where it runs. Browser, desktop app or your own GPU.
Batch processing. One image at a time or many.
Free tier and how you pay. Free, subscription, one-time app purchase, or credits per image.

Faithful vs creative upscaling: pick the right kind first

There are two kinds of AI upscaling, and choosing the wrong one is the most common reason people are unhappy with the result.

Faithful upscaling enlarges the image and sharpens edges and texture while keeping it looking like the original. Use it for real photos, family pictures, product shots, logos and anything with a face that must stay the same person.
Creative upscaling treats the image as a starting point and invents new detail: extra strands of hair, fabric weave, foliage, tiny texture on skin. It can look stunning on AI art and landscapes, and wrong on a portrait of someone you know.

Magnific and Krea lean creative. Topaz Gigapixel, Upscayl, Let’s Enhance, Photoshop and most phone apps lean faithful. On VdoBloom, Topaz Wonder 3.5 has Low, Medium and High enhancement strength: Low stays closest to the original, High enhances more.

1. Topaz Gigapixel

Best for: photographers who upscale often, need batch processing and want maximum control.

Gigapixel is Topaz Labs’ dedicated upscaler. It offers several models for different photo types, face recovery, and generative options for very low-resolution sources, and it processes whole folders at once on your own machine.

Watch out for: it is a paid desktop app that needs a capable computer, and it is more than most people need for an occasional upscale. Topaz’s Wonder 3.5 model is also available in VdoBloom’s browser upscaler, per image.

2. Magnific

Best for: AI artists and illustrators who want an upscale to add rich, new detail.

Magnific became known for “creative” upscaling with sliders for creativity and resemblance, prompts to guide the added detail, and style presets. On a soft AI render it can produce a far more detailed image than the original.

Watch out for: no free plan is listed, and on real portraits high creativity can change the face. Keep resemblance high for photos of people.

3. VdoBloom Image Upscaler

Best for: people who want a pro upscale model in the browser, priced per image by output size, without a subscription.

VdoBloom’s AI image upscaler holds three models in one tool. For Topaz Wonder it reads your image and shows the output dimensions and megapixels before you run it, so you know the price tier first.

Model	Output	Credits	Best for
Topaz Wonder 3.5	2× or 4×, up to 100 MP; Low, Medium or High strength	From 4, by output size	Photos, product shots, soft images, large prints
Riverflow 2.0 Pro (default)	2K or 4K	18 at 2K, 27 at 4K	An exact 4K target for screens and listings
Riverflow 2.0 Fast	2K	10	Quick 2K copies of web images and AI generations

Topaz Wonder 3.5 price by output size:

Output size	Credits	Example
Up to 8 MP	4	1024 × 1024 at 2× (4.2 MP)
Up to 16 MP	7	1920 × 1080 at 2× = 4K UHD (8.3 MP)
Up to 24 MP	11	3000 × 2000 at 2× (24 MP)
Up to 32 MP	14	Large poster prints
Up to 40 MP	18
Up to 50 MP	24	2000 × 1500 at 4× (48 MP)
Up to 64 MP	28
Up to 100 MP	45	The largest result it allows

The upscaler sits next to the rest of VdoBloom’s image tools on one balance, so you can restore an old photo (5 credits) or remove a background (1 credit) first, then enlarge the result. For video, use the separate AI video upscaler.

What it costs to start: 10 free credits at sign-up with no card, enough for one Riverflow 2.0 Fast upscale or two small Topaz Wonder upscales, plus 2 to 5 credits a day from the daily check-in. One-time packs start at $10.39 for 200 credits, or ₹299 for 75 credits in India; the Lite pack is 300 credits for $19.50. One-time credits never expire.

Watch out for: one image per run, with no batch upscaling. Topaz Wonder refuses results over 100 MP (inputs up to 64 MP), so very large photos are limited to 2×; the tool tells you before you spend credits. Riverflow 2.0 Fast stops at 2K. Free-account downloads carry a small watermark.

4. Let’s Enhance

Best for: people who need a photo at a specific print size without learning any settings.

Let’s Enhance runs in the browser, offers modes for photos, digital art and old images, and lets you target print dimensions directly. It is one of the simplest ways to make a small image big enough for a poster.

Watch out for: the free tier is a handful of images, and regular use means a subscription or credit pack.

5. Upscayl

Best for: anyone who wants a free upscaler and has a computer with a reasonable graphics card.

Upscayl is an open-source desktop app for Windows, macOS and Linux that runs upscaling models locally. Your photos never leave your computer, and there is no limit on how many you process, including batches.

Watch out for: speed and quality depend on your hardware and the model you pick, and there is no phone or browser version. Results on faces are good but behind the best commercial models.

6. Krea

Best for: AI image creators who want to enhance and upscale renders in the same place they make them.

Krea’s enhancer adds detail to AI images and supports large upscales, alongside its generation tools.

Watch out for: it leans creative, so check faces and text, and heavy use needs a subscription.

7. Adobe Photoshop

Best for: retouchers who want to upscale without leaving their editing workflow.

Photoshop offers Super Resolution through Camera Raw and newer generative upscaling built on Firefly. It fits naturally at the end of an edit.

Watch out for: it is a subscription, and dedicated upscalers offer more control over how much detail is added.

8. Canva

Best for: sharpening a photo that is going straight into a design.

Canva’s upscaler sits inside the editor, so you can enlarge a low-resolution photo and drop it into a template in one step.

Watch out for: it is a convenience feature on paid plans, with limited control and size options.

9. Pixelcut

Best for: online sellers and phone users who upscale product shots.

Pixelcut bundles an upscaler with background removal and product-photo tools, on the web and in mobile apps.

Watch out for: the free tier is limited, and it is tuned for product and social images rather than large prints.

10. Upscale.media

Best for: a fast 2× or 4× upscale in the browser with no setup.

Upload, choose a factor and download. It is handy for quick fixes on thumbnails and web images.

Watch out for: size limits on free use, and fewer controls than the dedicated tools.

How to upscale an image to 4K without losing quality

4K UHD is 3840 × 2160 pixels. Work out the factor from your image first:

Your image	Factor to reach 4K	On VdoBloom	Credits
1920 × 1080	2×	Topaz Wonder 2×	7
960 × 540	4×	Topaz Wonder 4×	7
1280 × 720	3×	Riverflow 2.0 Pro at 4K (or Topaz 4× and downscale)	27 (Riverflow)
Any size	Exact 4K target	Riverflow 2.0 Pro, 4K	27

Start from the original file. Not a screenshot, and not a copy sent through a chat app. Every round of compression removes detail the AI then has to guess.
Edit first, upscale last. Crop, retouch and remove the background, then enlarge the final version.
Use 2× before 4× when the source is already decent. Bigger is not always better on screens.
Use low strength on faces and text so the AI changes as little as possible.
Compare at 100% zoom with the original before you print or publish.

Can AI make a blurry photo clear?

Partly. AI upscalers fix soft focus, JPEG blockiness and small-image blur well, because they can predict plausible edges and texture. They struggle with heavy motion blur and badly out-of-focus shots, where the real shapes were never recorded. On VdoBloom, use Topaz Wonder 3.5 at 2× with Medium or High strength for a blurry photo. For an old print that is also scratched or faded, run Photo Restore first. Our guide to fixing a blurry AI image covers AI renders specifically.

How big do I need for printing?

A common rule is 300 pixels per inch for close viewing. An 8 × 10 inch print needs about 2400 × 3000 pixels (7.2 MP). A 16 × 20 inch poster needs about 4800 × 6000 pixels (28.8 MP) at that rule, though posters viewed from a distance look fine at lower density. On VdoBloom, a 24 MP result is 11 credits and a 32 MP result is 14 on Topaz Wonder 3.5.

Subscription, free app or pay per image?

You upscale hundreds of photos: a desktop app like Topaz Gigapixel, or free Upscayl if your computer can run it.
You want creative upscales every week: a subscription like Magnific or Krea.
You upscale now and then: pay per image. On VdoBloom the price shows before each run, and one-time credits never expire, so a quiet month costs nothing.
