300 → 1200
A form with a minimum size
Profile photos, listings and applications often reject small images. A 300 × 300 picture comes out at 1200 × 1200.

At a glance
- What it does
- Adds “Download upscaled” to the right-click menu on pictures. One click saves that picture 4× wider and 4× taller.
- Who it is for
- Anyone with the right picture at the wrong size: a logo for a slide, a product photo for a listing, a photo to print, an image a form rejects as too small.
- Price
- Free. No account, no paid version.
- Data
- Nothing is uploaded or sent to us. The picture is resized inside your browser and saved to your computer. Only your format choice is stored.
- Works in
- Chrome and other Chromium browsers that install from the Chrome Web Store. Not Firefox or Safari.
- Limits
- Always 4×. Resampling makes a picture bigger and smooth; it can't add detail that isn't there. Results stop at 16,384 pixels on the longest side.

When the picture is right but too small
4×
A bigger copy for a slide or print
Logos for a presentation, product photos for a listing, small photos you want to print larger. Four times the width and height to work with.
What it does
width and height
Every side becomes four times longer, so the picture has 16 times the pixels.
or WebP
Pick the format once in the popup. PNG is lossless; WebP is saved at quality 92 for smaller files.
AI
Plain resampling with the pica library and its mks2013 filter. Nothing is invented, so faces and text stay as they were.
Progress on the page
A small toast with a tape-measure bar shows how far it got, then confirms the download.
Clear file names
photo.jpg becomes photo-upscaled-4x.png, so the original is never overwritten.
pixel limit
Results are capped at 16,384 pixels on the longest side, the size browsers handle reliably.
Upscaling without AI: what it does and what it doesn't
An upscaler without AI computes every new pixel from its neighbours with a high-quality filter. The picture becomes four times wider and taller and stays smooth, without the blocky edges of a simple stretch.
AI upscalers go further and draw new detail, which can change faces, text and textures. Upscale Image In One Click doesn't: it keeps what is in the picture, so the result is predictable. When you need more pixels for a form, a slide or a print, that is usually what you want.
Your pictures stay with you
No uploads
The picture is resized inside your browser. No server of ours is involved.
No account, no tracking
Nothing to sign up for. No analytics, no telemetry.
Only what the job needs
A menu item on pictures, access to the picture you clicked, a small toast on the page, downloads to save the file, storage for your format choice.

| Where the picture goes | Usually to that site's server | Nowhere: it is resized in your browser |
| How it enlarges | Often AI that draws new detail | Resampling: no invented detail |
| Account, daily limits, watermarks | Depends on the site | None |
| Scale factor | Often 2×, 4× or more | Always 4× |
Questions
How do I upscale an image in Chrome?
Add Upscale Image In One Click to Chrome, right-click the picture and choose “Download upscaled”. A copy 4× wider and taller goes to your Downloads folder.
Does it use AI or add detail?
No. It resamples the pixels with a high-quality filter. The picture gets bigger and stays smooth, but no new detail is invented.
How do I increase image resolution for a form?
If a site asks for at least 1000 pixels and your picture is 300, upscale it: you get 1200. Then upload the new file.
Can I choose 2× or 8×?
No. The factor is always 4×. Results are capped at 16,384 pixels on the longest side.
PNG or WebP: which should I pick?
PNG is lossless and opens everywhere. WebP files are smaller and are saved at quality 92. Switch in the popup.
Is my picture uploaded anywhere?
No. The extension takes the picture from the site that shows it, resizes it in your browser and saves it to your computer.
Why did an upscale fail?
Some pictures can't be loaded by the extension, for example when the site blocks direct access to the file. The toast on the page then says the upscale failed.
Does it work in Edge, Brave or Opera?
Most Chromium browsers install extensions from the Chrome Web Store, including Edge, Brave, Opera and Vivaldi. Firefox and Safari are not supported.
