Compress Image to 25 KB
This free tool reduces your pictures to 25 KB each, right inside the browser. Plenty of websites, government portals and application forms cap uploads at a fixed size, and a file that is even a little too large gets rejected. Instead of guessing with a quality slider, you add your photos and every one is brought to 25 KB at the best quality that still fits.
Why compress to 25 KB
A 25 KB cap appears on application and exam forms that want a slightly better photo than a 20 KB limit allows. It keeps files small while giving a face a little more clarity.
Quality and size at 25 KB
25 KB is small enough for strict forms yet large enough to keep a face clear and easy to recognise. Most portrait sized images reach 25 KB with only modest quality loss, and the original width and height are usually kept. For an even smaller file, try compress to 20 KB. For higher quality with more room, use compress to 30 KB.
Compress many images at once
Add a single picture or a whole batch and each one is compressed to 25 KB on its own. Every file keeps its name with the size added, so they stay easy to tell apart. Download any image with its own button, or use the download button to save them all together in a ZIP when you have more than one. It works the same on a phone and a computer.
Common questions about 25 KB
Why pick 25 KB over 20 KB? The extra room lets the photo keep more detail, which helps if a 20 KB version looked too soft for the form.
What fits in 25 KB? A standard ID or passport style photo, with slightly cleaner edges than the same image at 20 KB.
