Tips for best results
- At this size the image has to be small in dimensions too. A close-cropped face or signature on a plain background compresses far better than a wide photo.
- The tool searches for the highest quality that still fits under 30 KB. If the photo is very large, it also scales the dimensions down automatically.
- Everything runs on your device. Your photo is not uploaded to any server.
- The output is a JPG. If your form asks for PNG or PDF, convert the compressed JPG afterwards.

How do I reduce a photo to 30 KB?
Select or drop your image, keep the target at 30 KB and press Compress. Download the result when it is ready.
Will compressing to 30 KB make my photo blurry?
It depends on the starting size. Large phone photos usually lose very little visible quality. For very small targets, cropping the photo first helps a lot.
Is it safe? Do you keep my photos?
No. Compression happens inside your browser, so the image never leaves your device.
