Increase image resolution 2x on your own device, free. The AI rebuilds edges and texture right inside your browser, which makes it useful for anyone holding a small avatar, an old thumbnail, or a tight crop that needs to hold up at a larger size.

Both panes below start from the same small source picture. On the right, the free image upscaler has rebuilt its edges and textures at twice the size, all of it computed inside your own browser.
This tool makes a narrow set of promises, all of them following from a small source and a model that runs on your own hardware.
This tool feeds the model a maximum long edge of 384 pixels, which caps the output at 768. Anything larger gets scaled down before processing, so a big photo comes back no bigger than that. Small sources are where the 2x is real, and the cap is what keeps the browser from running out of memory.
Swin2SR, a transformer based super resolution model, predicts the pixels a larger version would contain. It reconstructs edges and texture rather than spreading existing pixels thinner, which is why a 300 pixel avatar comes out at 600 looking rendered at that size instead of blown up to it.
Your image never uploads. The model downloads into your browser once and runs there through WebGPU, or a slower CPU path when your browser lacks it, so the file stays on your device from the moment you drop it in until you save the result. There is no server queue, no storage policy to read, nothing to delete afterward.
Running on your own hardware means each pass costs nothing to serve, so there is no reason to meter you. Run one image or fifty in a row, one after another, without a daily cap, a credit balance, or a paywall appearing partway through.
What downloads is a full resolution PNG and nothing else. No corner logo, no reduced quality export held back for paying users, no gate in front of the save button. First result and every result after belongs to you.
What these have in common is a source that was small before you ever opened it, not a photo you shrank by accident.
Drop a picture in, wait a moment, save the result. The whole run happens on this one page.
Click, drag and drop, or paste with Ctrl+V. Any format your browser can open works.
About a minute the first time, because the browser downloads the 54MB model once and caches it. Later runs start in seconds.
Check the original against the result side by side, then download the PNG.
The model does the reconstruction, but what you hand it decides how much detail comes back.
Crop To The SubjectTrim the empty margins first so the whole pixel budget goes into the part you care about.
Feed It Small FilesPictures with a short side under a few hundred pixels gain the most, which is exactly what this upscaler was tuned for.
Use The OriginalReach for the file straight from the camera or the download folder rather than a screenshot of it, and the upscaler has cleaner information to build on.
Keep One SubjectA single clear subject reconstructs better than a busy scene, so pick the frame with the least going on.
Paste It InCopy any picture and press Ctrl and V anywhere on the page to load it, no saving to disk first.

My forum avatar was a 200 pixel file from 2009 and every enlarger I tried turned it to mush. This one gave me a clean 400 that actually looks intentional. It took one drop and one click.

I crop faces out of group shots constantly, and those crops come out tiny. Running them through this before placing them holds the detail together better than my editor does. Local processing also keeps client material off other people's servers.

The cap on input size threw me at first, then I read why it exists and it made sense. For the small reference images I work with daily it is exactly right, and it never asks me to sign in.

Every image I pull out of an old slide deck has been squashed to a few hundred pixels by PowerPoint. This gets enough of it back that I can reuse the graphic instead of hunting for the original file.

What convinced me was watching the network tab stay quiet. The model loads once and then the image genuinely never leaves the browser, which is rare enough in this category that I checked twice.

I tried it on a handful of thumbnails, liked what came back, and moved the big batch to the paid version. Free version told me what I needed to know before I spent anything.

An AI image upscaler, sometimes sold as an image resolution increaser, raises a picture's resolution by predicting the pixels a larger version would contain. Instead of stretching the image until it blurs, the model reads patterns in the picture and reconstructs edges and texture at the new size. This free online image upscaler does that at 2x, entirely in your browser.
Sources with a long edge of 384 pixels or less, which come out at up to 768. Larger images are scaled down to that limit before processing, so a 2000 pixel photo returns at roughly 768 rather than 4000. The limit keeps browser memory use safe, and it is why this tool suits small sources.
Yes. No daily cap, no credits, no account. Run one image or fifty in a row and the save button stays open.
Yes. Drop in a JPG, PNG, or WebP and this photo upscaler returns a PNG, which spares the rebuilt detail a second round of compression. Whether you upscale PNG graphics or upscale JPG photos, the same fixed 2x pass applies.
The first run includes a one time download of the 54MB Swin2SR model. Your browser caches it, so later runs skip the download entirely. Speed after that depends on whether your browser supports WebGPU, with a slower CPU path as the fallback.
No. You get a full resolution PNG with nothing added, on the first result and every one after.
Not in this free browser tool, which handles one image at 2x. The cloud Image Upscaler takes larger inputs with a scale control from 1.0 to 4.0, one image per request, and a separate Video Upscaler handles video.
The Swin2SR model weights permit commercial use, and this tool adds no watermark or license claim to your output.
Mostly, yes. Image enlarger, photo enlarger and pixel upscaler are all names for a tool that adds pixels so a picture can hold up at a larger size. An image sharpener or photo enhancer is a different job: it adjusts the pixels you already have without adding any. This tool only adds pixels, at a fixed 2x.
