Shrink a photo to under 100 KB, a common limit for profile photos, ID scans and online form uploads.

Your files are processed on your device and are never uploaded.

About this tool

100 KB gives a photo more room than the stricter 50 KB or 20 KB limits, while still being small enough for most upload forms. This page opens Resize image with the target already set to 100 KB.

How to use it

  1. Choose your photo, or drop it onto the box.
  2. The maximum file size is already set to 100 KB.
  3. Select Resize and download your photo once it fits.

When this is useful

  • Profile photos on job and professional portals.
  • Scanned ID or document photos with a 100 KB cap.
  • Online forms that allow a bit more detail than a 50 KB limit.

Tips for best results

  • At 100 KB, most phone photos keep good detail without heavy compression.
  • If you only need to shrink pixels and not file size, switch to By pixels instead.
  • Keep proportions checked to avoid a stretched-looking photo.

Good to know

If your original photo is already smaller than 100 KB, the tool still resizes it for the pixel dimensions you choose, without adding unnecessary compression.

Your files stay with you

This tool opens and changes your photo inside your own browser. It is never uploaded.

Questions and answers

How is 100 KB different from 50 KB?

100 KB allows roughly twice the detail, so busier photos and backgrounds hold up better without visible blur.

Does this tool also change the pixel size?

Only if you ask it to. Leave width and height empty to keep the original dimensions and just shrink the file size.

What photo formats can I upload?

JPG, PNG and WebP. The result is saved as JPG by default when a target size is set, since it compresses far more efficiently.
