About compressing to this size
30 KB sits between the usual signature and photo limits, and shows up on scholarship, university and state recruitment forms. It leaves enough room for a clear passport photo at a typical form size.
How it gets to exactly 30 KB: the tool tries different JPEG quality levels and keeps the highest one whose file is still under 30 KB, so the result usually lands just below the limit (for example 27–30 KB). Only if quality alone can’t get small enough does it shrink the image dimensions, a little at a time.
Tip: Use JPG output — some government portals reject WebP even when the file is small enough.
Need a different size? 10 KB · 20 KB · 50 KB · 100 KB · 200 KB · 500 KB — or type any number into the “Target size” box above.
Frequently asked questions
How do I reduce a photo to 30 KB?
Drop the photo into the box above. The target is already 30 KB; download the result when it appears. It will be 30 KB or slightly less.
Will my photo look blurry at 30 KB?
The tool always keeps the best quality that fits. Faces and documents stay clear at common form sizes; very large photos may be scaled down slightly to fit.
Why is my file a little smaller than 30 KB?
Portals reject files even 1 byte over the limit, so the tool stays safely under 30 KB instead of going over.
Are my photos uploaded to a server?
No. The compression runs entirely in your browser, so your photos never leave your phone or computer.
Does it work on mobile?
Yes — open this page on your phone, tap the box, pick a photo from your gallery and download the result.
