Quick answer

To compress an image to 50 KB, drop it in and press Resize: the target is already set to 50 KB, and the tool finds the highest quality that fits. It runs on your device, so the picture is never uploaded.

Also takes BMP, GIF, SVG and AVIF. They are turned into PNG first (a GIF keeps its first frame).

How to use it

  1. Drop your JPG, PNG or WebP picture, or paste it from the clipboard.
  2. The target size is already set to 50 KB and the pixel size is kept as it is.
  3. Press Resize. The tool tries different quality levels and keeps the best one that fits.
  4. Check the result size in the list, then download it.

Fifty KB is typical for signature and thumb impression uploads, which are small and mostly white, so they shrink easily.

A cropped signature usually goes under 50 KB without any visible change. If the photo is very large, 50 KB may need a smaller pixel size as well as lower quality. In that case the tool tells you, and you can lower the width on the Resize images page and try again.

PNG is a lossless format, so it cannot be squeezed to an exact size by quality alone. A PNG with a target size is saved as WebP, which is much smaller. If a form insists on JPG, use the Convert images page first.

Common questions

How do I get a photo under 50 KB without it looking bad?

Leave the pixel size alone first. The tool lowers the JPG or WebP quality step by step until the file is 50 KB or less, which keeps the picture sharp for as long as possible. Only if that is not enough do you need to reduce the width as well.

Is my picture uploaded anywhere?

No. The compression runs inside your browser tab. The file is not sent to our servers, so it also works for private photos and documents.

The result is bigger than 50 KB. What now?

The picture has too many pixels for 50 KB at an acceptable quality. Open Resize images, set a smaller width (for example 800 pixels), keep the target at 50 KB and run it again.

Does it work on my phone?

Yes. Tap the drop area to choose a photo from your gallery or take a new one. Many forms ask for a size limit, and phones usually produce files of several MB, so this is a common job.
