What fits in 15 KB
| Picture | As JPG | As WebP |
|---|---|---|
| A detailed camera photo, 3:2 | about 410 by 270 px | about 470 by 310 px |
| A head-and-shoulders portrait, 3:4 | about 300 by 410 px | about 470 by 620 px |
Measured at good quality (80 %) on two real photos. Plain backgrounds, signatures and drawings fit far more pixels; busy pictures, such as leaves or crowds, fewer.
When 15 KB is asked for
- Signature uploads that allow 10 to 20 KB.
- Small photo uploads on older government and exam portals.
- Thumbnails for listings and directories.
Tips for 15 KB
- Resize to the pixel size the form names before compressing; a 300-pixel-wide photo fits easily, a full camera photo does not.
- For a signature, use dark ink on plain white paper and crop close around it.
- JPG is what most forms ask for. WebP fits more, but only use it if the form accepts it.
- If the form gives a range, such as 10 to 20 KB, aim for the middle so the file passes either way.
Frequently asked questions
How do I resize or compress an image to 15 KB?
Choose your image and press Compress: on this page the size is already set to 15 KB. Then download the smaller file.
Will the file be exactly 15 KB?
As close as it can get without going over. ChobiKit tries different qualities and keeps the best one that stays under 15 KB, so the file may come out a little smaller.
Is 15 KB counted as 15,000 or 15,360 bytes?
Forms differ, so ChobiKit keeps the file under 15,000 bytes, which passes either way.
My form says 10 to 20 KB. Is 15 KB right?
Yes: 15 KB sits in the middle of that range, so the file passes whether the form counts a KB as 1,000 or 1,024 bytes. If the form also gives a pixel size, resize to it first.
Why won't my image get under 15 KB?
It has too many pixels for 15 KB even at the lowest quality. ChobiKit then offers to make it smaller in pixels and tries again. Cropping away what you don't need helps too.
Is my image uploaded?
No. It is compressed in your browser and never sent to a server. It is free, with no sign-up and no watermark.
