How to reduce an image to 100 KB

1. Add your photo. Tap the box or drag the file in. Nothing leaves your device at any point.
2. Press the button. The tool re-saves your image again and again at different quality settings, looking for the best-looking version that is still 100 KB or less.
3. Let it shrink if needed. If quality changes alone cannot reach 100 KB, the tool carefully steps the dimensions down too — this is the only way very detailed photos can reach small targets.
4. Download and upload. Save the result and use it in your form, listing or email. Your original photo is unchanged.

Small size limits like 100 KB are common on exam and job application portals, visa forms, marketplace listings and older email systems. A modern phone photo is often 3–8 MB — thirty to eighty times too big. Guessing quality settings by hand can take a dozen tries, which is why this tool automates the search. It tries the JPG format first, then WebP, and keeps whichever result fits best. Our guide to reducing a photo to 50KB or 100KB for online forms covers the full upload checklist — dimensions first, then file size.

Honest note: a few photos genuinely cannot reach 100 KB at any readable size — for example a sharp scan of a full page of tiny text. If that happens, the tool tells you plainly and gives you the smallest file it could make, plus a tip: crop tightly to the important part and try again.
