About Compress Image

Compress JPG, PNG and WebP images online free with quality and target KB controls. No upload, no signup. The work happens in your browser, so the selected images stay on your device while you prepare the result.

Reducing JPG, PNG and WebP files for forms, email attachments and website uploads.

Targeting a specific KB limit without sending the original image to a remote converter.

Practical notes

Photos usually compress well as JPEG or WebP, while screenshots and transparent graphics often need PNG or WebP.
If a strict KB target is hard to reach, reduce dimensions first and then compress.

Common questions

Can I compress an image to a target KB size?

Yes. Set the target KB value and FreeConvert will try to export a smaller file that matches the limit.

Which format is best for compressed photos?

JPEG and WebP usually work best for photos, while PNG or WebP are better when transparency is needed.

Does image compression happen privately?

Yes. Compression runs locally in the browser without uploading your image to FreeConvert servers.
