When 500 KB is the right ceiling

Some portals and email workflows allow a few hundred kilobytes per photo — enough for readable document scans and ID photos without the harsh limits of 20 KB signatures.

This preset targets 500 KB JPG output so you can attach scans or portraits without manually tuning quality.

How to use it

  1. Upload the image you need to send or submit.
  2. The tool finds a strong quality level under 500 KB.
  3. Download and confirm size before you attach or upload.

Tighter limits? Use 100 KB or 20 KB tools. For email-friendly sizing, see compress for email.

If you still exceed 500 KB

Reduce pixel dimensions in the resize editor first — especially for phone photos above 3000 px wide — then run this tool again.

Frequently asked questions

How do I compress to 500 KB?

Upload your file above. The server returns a JPG at or under 500 KB when possible.

Is 500 KB good for email?

Often yes for a few photos per message, but check your provider’s total message limit. Merge scans to PDF when you have many pages.

PNG or JPG output?

This tool outputs JPG for compatibility. Use the PNG compressor page if you need transparency.
