Compress signature to 20KB

Compress signature to 20KB for online forms, exam portals, applications, identity uploads, and strict scanned-signature limits.

Use this page when a form asks for a signature image under 20KB, scanned signature below 20KB, or a small upload-ready signature file.

Set 20KB and compress

Upload the file, choose KB, enter 20, then download the result when compression finishes in your browser.

Match the upload wording

20KB, 20 KB, maximum 20KB, and under 20KB usually describe the same upload limit.

Choose the exact number from the form first, then use format or resize controls only when the portal still rejects the file.

Questions people ask

Which format is best for a signature under 20KB?

PNG can keep signature edges cleaner, especially on a transparent or plain background. JPG may be smaller for scanned paper signatures.

How do I keep a signature readable at 20KB?

Crop extra blank space, keep dimensions modest, and avoid heavy backgrounds before compressing.

Can I use this for government or exam portals?

Yes, but always compare the final file with the portal rules for size, dimensions, background, and accepted format.
