Actually Free: Compress Image to Under 20 KB

Reduce a photo to under 20 KB free for online forms — best quality that fits, dimensions reduced only if needed. No upload.

What it does

To compress an image to under 20 KB for free, drop it here with the 20 KB target preselected. ActuallyFreeTools searches for the highest JPEG quality that fits and shrinks the dimensions only when quality alone is not enough. If your form also demands exact pixels or a minimum size, use Photo & signature for forms.

How to use it

  1. Drop the photo — 20 KB is preselected.
  2. Leave “Allow shrinking the dimensions” ticked.
  3. Compress and download.

Questions people ask

Why must it be under 20 KB?

Many exam and job portals limit signature and photo uploads to 10–20 KB.

My form also says 140 × 60 pixels.

Use Photo & signature for forms to set the pixels, KB range and DPI together.

Will it look blurry?

At small display sizes 20 KB looks fine; large photos lose fine detail.

Is Compress images on ActuallyFreeTools really free?

Yes. There is no sign-up, no daily limit, no watermark and no paid tier. Nothing is held back for paying users.

Are my files uploaded anywhere?

No. Compress images runs inside your browser, so your files are processed on your own device and never sent to a server. That is also why there is nothing to meter or charge for.
