AI image upscaler
Upload a photo and get it back at twice or four times the size, with its edges and textures kept sharp. A super-resolution model adds the pixels from what is in the picture; nothing is redrawn, so a face is still the face and a label still reads.

What is an AI image upscaler?
An AI image upscaler increases an image's resolution: it makes the picture two or four times larger and rebuilds edges and texture so it stays sharp instead of blurring. It is for prints, large screens, product listings and old or small photos. It is part of every DreamBench plan, from $9.99 a month.
How to upscale an image
Upload a photo
Drop in a picture, paste one, or pick it from your device: a photo, a product shot, a scan, a screenshot, a render.
Pick 2x or 4x
Twice the size keeps the most of a photo's own look; four times is for a small picture that has to be printed or shown large. Then press Upscale the image. The first time, create a free account and choose a plan.
Download the upscaled image
See the result beside the original in the page, then download the full-size file: a PNG when your upload is a PNG, a JPEG otherwise.
Should I pick 2x or 4x?
A social post or a website
2x. A screen shows at most a couple of thousand pixels across, and the apps shrink every upload again, so doubling a soft or small picture is enough.
A print at A4 or a poster
4x. Photo labs print at about 300 pixels per inch, so an A4 sheet wants about 2480 × 3508 pixels and a poster more. From 1024 pixels up, a run returns the 4096-pixel cap either way.
A 4K screen or TV
4x. A 4K screen is 3840 × 2160 pixels: a picture of up to 960 pixels wide reaches it at 4x, and a 1920-pixel one is doubled to the same size and resized to 4096.
A small old scan or a tiny photo
4x. A picture of a few hundred pixels gains the most from the strongest pass. Repair scratches and fading with the photo restoration tool first, then upscale the repaired scan.
Uses
Upscale an image for print
Photo labs print at about 300 pixels per inch, so the 4096 pixels a run can return cover about 35 cm (13.7 in) on the long side; at 150 pixels per inch, enough for a poster seen from a step back, about 69 cm (27 in). The DPI setting itself changes nothing: pixels decide the print size. An 8 × 10 inch print needs 2400 × 3000 pixels, which a 600 × 750 picture reaches at 4x: multiply inches by 300. The file grows too, four or sixteen times the pixels, a PNG most of all.
Upscale an image to 4K
Four times larger, up to 4096 pixels on the long edge: the size a 4K screen, a wallpaper or a banner asks for. The 4K page fixes 4x and explains which pictures reach the full 4096.
4K image upscalerSharpen a blurry or pixelated photo
A soft phone photo or a small, blocky picture saved from a message comes back crisper at the larger size. The unblur page explains which blur can be fixed and which can't: a badly out-of-focus or shaken photo stays blurred.
Unblur image toolMake a small photo HD
A profile picture, a scan or a photo pulled from a web page doubled in size, crisp enough for a slide or a big screen, with no retouching. The photo enhancer is the 2x preset of this tool.
AI photo enhancerUpscale a screenshot, a logo or a graphic
A PNG upload comes back as a PNG, so flat color, straight edges and lettering stay lossless, and a transparent logo keeps its transparency; a JPEG comes back as a JPEG, and saving it as a PNG first adds nothing. Text that is only a few pixels tall has little to rebuild from, so check it at full size.
Upscale an illustration, anime art or an AI image
Drawings, anime art and AI renders upscale like photos: flat color and line art come back with clean edges at the larger size. A Midjourney, DALL-E or Stable Diffusion render, usually about 1024 pixels, reaches the 4096 cap at 4x. Upload a PNG to keep it lossless. Lines only a pixel wide can thicken or break, so check them at full size.
2x or 4x: which to pick
From a 500-pixel picture, 2x gives 1000 pixels and 4x gives 2000. From 1000 pixels, 2000 or 4000; from 1024, 2048 or 4096; from 2048, 4096 either way. Pick 4x for a picture of up to 1024 pixels that must be shown large, and 2x for one that is already a good size.
Works with
- What it takes
- JPEG, PNG, WebP or HEIC, up to 40 MB, straight from a phone or a camera. An iPhone's HEIC photo becomes a JPEG on your device as you choose it, in any browser. A picture larger than 2048 pixels on its long edge is scaled to 2048 before the run.
- What you get
- A PNG when you upload a PNG and a JPEG otherwise, up to 4096 pixels on its long edge.
- Photo labs and print shops
- Send the full-size JPEG or PNG; the print size comes from its pixels at the lab's resolution, as above.
- 4K screens and wallpapers
- A 4096-pixel side is wider than a 4K screen's 3840, so a 16:9 result fills one edge to edge.
- Shopify, Etsy and Amazon
- A larger image lets a listing's zoom show detail; each marketplace has its own minimum and maximum sizes.
- Photoshop, Lightroom and Canva
- Open the result as any photo; a PNG upload stays a PNG, transparency included.
Worth knowing
Which model runs it, and where it fails
Runs on Real-ESRGAN. Real-ESRGAN is an open-source super-resolution model from Tencent ARC Lab, trained to undo the blur, noise and compression of real photos as it adds pixels. It rebuilds edges and texture from what the picture holds. DreamBench runs it on fal with face retouching switched off, so a face is sharpened but never redrawn.
The same picture, more pixels
A super-resolution model, not a generative repaint: it sharpens edges and rebuilds textures from what the picture holds, with no face retouching and nothing added that was not there.
2x or 4x, up to 4096 pixels
A 1000-pixel photo becomes 2000 or 4000 pixels on its long edge. The cap is 4096, enough for a print, a large screen or a crisp crop.
Faces, text and logos stay themselves
Because nothing is redrawn, a person is still recognizably that person, and the writing on a sign or a label stays the writing it was.
A sharper reference for a video
Animate this image opens the composer with the upscaled picture as a reference image, for a clip on any DreamBench model.
Where it fails
- Detail the camera never caught can't be brought back: a photo that is badly out of focus or smeared by motion stays blurred, only larger.
- Heavy JPEG blocks and noise can be sharpened along with the picture; a cleaner copy of the same photo gives a cleaner result.
- Fine, busy texture such as grass, fur or skin can come out smoother than real at 4x; compare at full size.
- Nothing larger than 4096 pixels: a picture already that size or bigger comes back no larger.
AI image upscaler FAQ
How do I upscale an image?
Upload the image, choose 2x or 4x, and press Upscale the image. Make it with any DreamBench plan: the result appears beside the original on the page when the run finishes, usually well under a minute, ready to download as the full-size file.
Does the upscaler invent detail that was not in the photo?
No. It runs a super-resolution model that works from the pixels you upload: edges are sharpened and textures rebuilt from what is there, so a face stays the same face and text stays the same text. Face retouching is switched off on purpose; nothing is redrawn.
Can it fix a blurry photo?
A slightly soft photo looks crisper, because edges and fine texture come back sharper at the larger size. If your image is still blurry after upscaling, the blur was in the original: a photo out of focus or shaken when it was taken has no sharp edge to rebuild, so it comes back larger with the same blur.
What size do I get?
Twice or four times the width and height of the picture the run starts from, up to 4096 pixels on the long edge; a picture larger than 2048 pixels is scaled to 2048 first. At 4x, the model enlarges a picture of up to 1024 pixels 4x, and a larger one 2x, which is then resized to 4096. There is no 8K, which is 7680 pixels wide.
Does upscaling change the DPI of an image?
DPI, or PPI, is a note in the file that tells a printer how many pixels to put in an inch; it adds no detail. What upscaling changes is the number of pixels, which is what decides how large a picture prints sharply. Set the DPI your print service asks for when you order.
Can I upscale an image in Photoshop, Canva or on my iPhone instead?
Photoshop has Generative Upscale, which enlarges 2x or 4x and can redraw detail, and Super Resolution in Camera Raw and Lightroom, which doubles a picture; Canva has an upscaler in its editor; Upscayl is an open-source desktop upscaler for Mac, Windows and Linux. This page works in the browser on any phone, tablet or computer, with nothing to install.
Can it upscale a video?
No. It upscales one still image at a time, and DreamBench has no video upscaler. A frame saved from a video can be upscaled like any picture, and DreamBench's video models make clips at their own resolutions in the composer.
Does upscaling an image reduce quality?
Upscaling an image does not reduce its quality: no pixels are taken away. A plain enlargement spreads the same pixels further and looks soft; a super-resolution upscaler sharpens edges as it adds pixels. It cannot add detail the original never had, so blur and heavy JPEG blocks stay, only larger.
How can I upscale an image without losing quality?
To upscale an image without losing quality, start from the original file and let a super-resolution model add the pixels: it sharpens edges and rebuilds texture from what the picture holds instead of stretching it. Upload graphics as PNG to keep them lossless, pick 2x if the picture is already large, and compare at full size.
What is the difference between upscaling and resizing an image?
Resizing stretches the pixels an image already has, so a bigger copy looks soft. Upscaling with a super-resolution model works out new pixels from the edges and textures in the picture, so the bigger copy stays sharp. Both keep the framing and aspect ratio; only upscaling keeps the sharpness.
Super-resolution or generative upscaling: which should I use?
Pick by whether the picture may change. A super-resolution upscaler, which this is, keeps the same picture and adds pixels: a face is still the face and text still reads. A generative upscaler redraws detail, which can look sharper but can change faces, lettering and texture. For a real person, a product or a document, keep the picture.
Does AI upscaling change my image's composition or aspect ratio?
No. The width and the height grow by the same factor, so the framing and the aspect ratio stay exactly as they were: nothing is cropped, extended or moved. To change the shape of a picture, use the AI image expander, which adds new borders around it.
Should I restore an old photo before upscaling it?
Yes, if it has scratches, tears or fading: the photo restoration tool repairs those, and the upscaler then enlarges the repaired picture. Upscaling first would only make the damage larger and sharper.
Can I use the AI image upscaler without paying?
No. Every run needs a DreamBench plan; you create an account on the way, and the button shows the price in credits before you press it. A run that fails is refunded.
Can I upscale several images at once?
No. The upscaler takes one picture per run, and there is no batch upload. Run it again for the next one: each run is priced separately, and the button shows the price before you press it.
Does the upscaled image have a watermark?
No. A DreamBench tool adds no watermark to an image it returns, on any plan, and the super-resolution model that runs this page embeds no mark of its own. The download is your picture with more pixels, nothing written or hidden in it.
How much does the AI image upscaler cost?
Each run uses 7 credits from your DreamBench plan. Starter, $9.99 a month, includes 1,100 credits a month, about 157 runs of the AI image upscaler, plus AI video. A run that fails is refunded.
Do I need an account to use the AI image upscaler?
Yes: a free account and a DreamBench plan. The tools are part of every plan, from Starter at $9.99 a month.
Which image files does the AI image upscaler take?
A photo up to 40 megabytes: JPEG, PNG, WebP, HEIC or another format your browser opens. A photo straight from a phone is fine, an iPhone's HEIC included: the page scales a large picture down to 2048 pixels on its long edge before the run, so the result is never larger than the page says.
Can I use what the AI image upscaler makes commercially?
Yes. Under the DreamBench Terms you may use what a tool makes for personal and commercial purposes, including advertising, monetized content and work for clients, with no separate commercial-use upgrade. The Terms don't guarantee copyright in a result or clear another person's rights in your upload, so only use photos you have the rights to.
Is my photo used to train AI?
No. DreamBench doesn't use your prompts, uploads or videos to train or fine-tune AI models, and any future training program would be opt-in.
What happens to my uploaded photo?
It stays in your browser until you make a result. Then it is used to make that result and nothing else, and removed from the tool's storage after seven days along with the result. A result you keep in your library stays as long as you keep it.
