Compress Image to 30KB

Bring a photo down to 30 KB - a little more headroom than 20 KB, still small enough for strict forms.

The Middle Ground Between Signature and Photo Limits

30 KB sits in a useful gap. It is generous enough that a small headshot keeps recognisable detail, and tight enough to satisfy forms that treat anything above 50 KB as too big. If a portal gives you a range rather than a hard number - "between 10 KB and 50 KB" is common - 30 KB is a safe middle to aim for, because it clears the minimum without brushing against the maximum. Set the target, check the preview, and download; if the result looks soft, nudge the target up rather than accepting a blurry upload.

How to Compress an Image

1

Upload your image

Pick a JPG, PNG, WebP, or GIF file from your device. It stays on your computer - nothing is sent to a server.

2

Set a target size or quality

Type the exact KB size a form or upload limit requires, tap one of the presets, or switch to the quality slider for manual control.

3

Download the compressed file

Check the before and after sizes, then save the smaller image in JPG, PNG, or WebP.

When 30 KB Is the Right Target

  • Forms that specify a 10-50 KB range for photos or signatures
  • Small profile pictures on membership and alumni portals
  • Document thumbnails attached to an application record
  • Compressing a scanned ID photo before emailing it
  • Product thumbnails on a listing page that must load fast
  • Any upload where 20 KB looks too rough but 50 KB is refused

Compressing to 30 KB

How much quality do I lose at 30 KB?

That depends on the pixel dimensions. A 300 × 300 photo at 30 KB looks fine; a 3000 × 2000 photo at 30 KB will not. Resize first if your image is large and detail matters.

My form says 10 KB to 50 KB - what should I pick?

Aim near the top of the range for the best quality that still passes. 30 KB is a safe middle, and 45 KB is usually accepted if the maximum is 50 KB.

Can I go back if 30 KB is too small?

Yes. Change the target number and the result updates immediately - nothing is committed until you download.

Does compressing twice make it smaller?

No, and it will look worse. Always compress the original file rather than a file you already compressed.
