How it works
100 KB leaves plenty of room for a sharp photo at the sizes forms ask for, and it is a common limit for website images and email attachments.
- 01
Select your images
Tap Select images, or drop files here. JPG, PNG, WebP and iPhone HEIC photos all work.
- 02
We fit them under 100 KB
Quality stays as high as the limit allows. If a photo is too big, its dimensions shrink just enough, and the new size is shown.
- 03
Check and download
Each file shows its final size with a green tick. Download one by one or all at once as a ZIP.
Forms that use 100 KB
NEET and JEE Main allow signatures of 10 to 100 KB, UPSC 20 to 100 KB, and CTET photos of 10 to 100 KB, according to their recent notices. Check your own notice for the exact rule.
For websites and email
Images under 100 KB load fast on phones. For website images, WebP saves even more space at the same quality; choose it under Format in Settings.
Questions people ask
Is 100 KB counted as 100000 or 102400 bytes?
Forms disagree, so we keep files under 100,000 bytes. That passes whichever way a form counts a kilobyte.
Are my photos uploaded anywhere?
No. The resizing happens inside your browser, on your device. Our code never uploads your images, and the page works the same way offline once loaded.
What if the form also has a minimum size?
Open Settings, choose Size range and enter both limits, for example 10 to 20 KB. If an image ends up too small, the tool can pad it to the minimum without changing the picture.
