Compress an image to 50 KB

Exam registrations, visa portals and many official forms ask for photos or signatures under 50 KB. Add your image and the tool will produce the best-looking file that fits under the limit.

JPG, PNG or WebP · up to 40 MB each · max. 50 images

Your images never leave your device. All compression happens directly in your browser.

How to get an image under 50 KB

  1. Add your photo or scanned signature (JPG, PNG or WebP).
  2. The 50 KB target is preselected. Keep “Reduce dimensions if needed” enabled for the best quality.
  3. Download the result — or use the ZIP button if you compressed several files.

What to expect from a 50 KB image

50 KB is small: a typical photo needs to be around 600–900 pixels wide to look clean at that weight. That is plenty for a passport-style photo on a form, but not for printing a poster.

Scanned signatures and documents with a white background compress very well because they contain few colours. They often stay sharp at 50 KB even at larger dimensions.

Tips for small file limits

  • Crop tightly around the face or signature before compressing.
  • Scan or photograph documents in good light so the background is pure white rather than grey and noisy.
  • If the form requires specific dimensions (for example 200 × 230 px), type the larger value in “Max width / height”.
  • For signatures on a transparent background, keep PNG: JPG would fill the transparency with white.

Common questions

My image is still over 50 KB. What can I do?

Make sure resizing is allowed, crop the image, or try WebP if the website accepts it. If the target cannot be reached, the tool shows the closest result and tells you so.

Will the image look pixelated?

The tool prefers reducing dimensions slightly over using very low quality, which keeps edges clean. Use the before/after view to check.

Does it work on my phone?

Yes. It works in modern mobile browsers, and the photo is processed on the phone itself.
