Reduce any photo to a 30KB file size for forms that sit between the 20KB and 50KB limits — free and processed entirely in your browser.

The 30KB sweet spot

30KB sits neatly between the very strict 20KB limit and the more comfortable 50KB. It's small enough for tight portals yet keeps a headshot a little clearer than 20KB does.

Compress to 30KB

Upload your image and download a version under 30KB. The target is preset, but you can change it if your form needs something slightly different.

Quick quality tips

  • Crop out empty background before compressing.
  • For a passport-style photo, keep dimensions modest so 30KB stays sharp.
  • Start from your highest-quality original rather than an already-compressed copy.
All compression is done locally — your image never leaves your device.

Frequently Asked Questions

Is 30KB enough for a passport photo upload?

Often yes, especially at typical passport pixel dimensions. Check your form's exact requirement and set the target to match.

Can I choose a different size later?

Yes. The KB value is editable so you can target any size a form asks for.

Will there be a watermark?

No. The output is a clean JPEG with no watermark.
