Compress image to 100 KB
Online forms, government portals, job sites and some email systems cap uploads at 100 KB. A photo straight from a phone is 2–5 MB, so a plain "compress" button rarely gets there. This page presets a 100 KB target: the tool lowers JPEG quality in steps, checks the size after each step, and only if the lowest acceptable quality is still too big does it scale the image down, a little at a time, until the file fits.
Options
Everything runs in your browser. The photo is never uploaded, and the result shows the exact size so you can see it is under the limit before you download.
Tips
- A PNG screenshot usually cannot reach 100 KB without losing its lossless format; the tool switches it to JPEG for you. Pick WebP in Format if the form accepts it: same size, better quality.
- If the result looks soft, your original was large; a 1200 px wide photo at quality 70 is typically 90–120 KB and still sharp on screen.
- Need 100 KB for an ID photo? Keep the face centred and crop before compressing; fewer pixels means more quality budget per pixel.
Why it is private
Everything you type or drop here is handled by your browser, on your device. Nothing is uploaded. To verify, open your browser's developer tools, go to the Network tab, and use the tool: you will see no request carrying your data.
Frequently asked questions
- Is the result exactly 100 KB?
- It is at or under 100 KB (102,400 bytes). Most sites count 1 KB as 1,024 bytes; if yours counts 1,000, set the target to 50 KB or add a little margin.
- Why did my image get smaller in pixels?
- Only when quality alone could not reach the target. The tool reduces dimensions by 20% at a time and stops as soon as the file fits.
