How to use this tool

  1. Add one image. Drop a JPG, PNG or WebP onto the box or click to browse. Each file can be up to 20 MB.
  2. Choose a method. Switch between Pixels for a precise width and height, Percentage to scale the whole image, and Presets for common social and passport sizes.
  3. Adjust the numbers. With Keep aspect ratio ticked, editing one side recalculates the other so the photo is never stretched. Untick it if a form demands a shape that differs from your file.
  4. Watch the preview. The panel shows the original and new dimensions plus both file sizes, and refreshes shortly after you stop typing.
  5. Download. Your resized file keeps the original format and is saved with the new dimensions in its name.

Why use this tool

Upload forms rarely explain how they want a photo prepared. One asks for 413 × 531 px for a passport, another wants 1080 × 1080 px for a shop listing, and a third silently rejects anything wider than 1,200 px. Typing those numbers into an editor and exporting over and over is tedious. Here the target is a field, not a guess.

The preset list covers the sizes people ask about most often: passport photos, Instagram posts and stories, Facebook covers and YouTube thumbnails. Because the conversion runs on your own machine, a photograph of an ID card or a family picture is never sent to a stranger's server. There is no queue either, so a large file resizes at the speed of your browser.

Frequently asked questions

Does the resizer upload my photo?
No. The image is decoded and redrawn in your browser with the Canvas API, so no copy is sent anywhere. You can even disconnect from the internet after the page loads.
Why is part of my photo cut off when I use a preset?
Presets have a fixed shape. When your photo has a different shape, the tool scales it to fill the preset and crops the extra edges from the centre. That is what keeps a square Instagram post truly square. Use the Pixels tab with Keep aspect ratio if you would rather keep the whole frame.
Can I make an image larger than the original?
Yes. Width and height can go up to 12,000 px, but enlarging cannot add detail that was never in the photo, so very large enlargements may look soft. For print work, start from the highest-resolution original you have.
Does resizing change the file format?
No. A JPG stays a JPG, a PNG stays a PNG and a WebP stays a WebP. Only the pixel dimensions change, which makes the download easy to drop back into the site or form you came from.
