About Compress Image to 150 KB
Many forms and websites reject pictures over 150 KB — most often for application photos and scanned ID documents on official portals. Add your photo or scan and the tool finds the highest quality that fits under 150 KB, so you don’t have to guess or retry.
If even a low quality is too big, the picture is made just small enough to fit, keeping it sharp. Keep JPG or switch to WebP for even better quality at the same size, compress many images at once, and check the before / after preview — all in your browser.
Good for
- Uploading photos and signatures to application forms
- Meeting attachment limits on email and chat
- Saving space while keeping photos sharp
Tip: Crop away empty background before compressing — the subject keeps more detail at the same file size.
Frequently asked questions
How do I get an image under 150 KB?
Add the image — the target is already 150 KB. The tool tries qualities from high to low and keeps the best one that fits; if even a low quality is too big, it makes the picture slightly smaller so it still looks sharp.
Where is a 150 KB limit used?
Most often for application photos and scanned ID documents on official portals.
Will the image still look good?
Yes. At 150 KB most photos look the same as the original on screen.
Is 150 KB measured exactly?
Yes — every file is made 150 KB or a little less, measured in bytes (1 KB = 1000 bytes), so it is also under the limit on websites that count 1 KB as 1024 bytes.
Can I compress several images to 150 KB at once?
Yes. Add as many as you like; each one is compressed to the limit and you can download them together as a ZIP.
Are my documents uploaded?
No. Your browser compresses the files itself, so nothing is sent anywhere.
