How to compress an image to 10KB
- 1
Choose your image
Pick a JPG, PNG or WebP from your phone or computer, or drop it onto the box.
- 2
Keep the 10KB target
The target is already set to 10KB. You can change it if your form needs a different limit.
- 3
Download
Check the preview and the new file size, then download the compressed JPG.
Tips for a clear image under 10KB
- Crop tightly first. A head-and-shoulders photo or a signature compresses far better than a full scene.
- Expect smaller dimensions: at this size the compressor reduces the pixel size so the image stays clear instead of blocky.
- A plain, light background takes far fewer bytes than a busy one.
- If the form also states pixel dimensions, use the photo resizer to hit both the size and the KB limit.

Need exact pixel dimensions too? Use the photo resizer. Shrinking a document instead? Try compress PDF.
Frequently asked questions
Will the file really be under 10KB?
Yes. The compressor keeps the file at or below the target, using 1KB = 1000 bytes so it passes whether a site counts kilobytes as 1000 or 1024 bytes.
Why did the dimensions of my image change?
When a target is too small for the full-size image, lowering the quality alone would make it blocky. The compressor reduces the pixel dimensions instead, so the result stays clear. Tick “Keep original dimensions” to change only the quality.
Is my photo uploaded anywhere?
No. Compression happens entirely in your browser. The image never leaves your device.
Which formats are supported?
JPG, PNG and WebP, plus anything else your browser can open. The result is always a JPG, the format most forms accept. Transparent areas of a PNG become white. iPhone HEIC photos open in Safari; in other browsers, convert them to JPG first.
Is it free?
Yes, completely free, with no sign-up, no watermark and no limit on how many images you compress.
