Compress an Image to 50 KB

About this option

Some forms — especially for signatures, stamps and small ID pictures — allow only 50 KB. Reaching that means shrinking both the quality and the dimensions. This page opens the compressor on a 50 KB target with the width capped at 1000 pixels.

When to use it

  • A signature or thumbprint upload has a 50 KB maximum
  • A passport-style photo must be tiny to submit online
  • You need a very light image for a slow connection

How to use it

  1. 1Drop your picture — 50 KB and a 1000 px width limit are preselected
  2. 2Click Compress
  3. 3Check the file size; reduce the max width to 600 if it is still too big
  4. 4Download the JPG

Frequently asked questions

Why is the width limited?

Very small file sizes are mostly reached by reducing the number of pixels. A 1000 px width is plenty for a form photo.

The result is slightly over 50 KB — what now?

Lower the max width a little, for example to 800 or 600 pixels, and compress again.

Will text on a signature stay readable?

Usually yes at 1000 px wide, but check the preview; scan signatures at higher contrast for the best result.
