Compress image to 100 KB
Many online forms reject photos above a fixed size. Drop your image below and PhotoReducer will automatically find the highest possible quality that stays under 100 KB — you can also pick a different limit.

How it reaches the exact size
The tool searches for the best quality level whose result stays under your target. If compression alone is not enough, it scales the image down slightly and tries again, always keeping the largest, sharpest version that fits the limit.
Typical uses
Job application portals, visa and passport forms, university admission sites and government websites often cap uploads at 20, 50, 100 or 200 KB. Because everything runs on your device, this is also the safest way to prepare ID photos and documents — nothing is ever uploaded.
Frequently asked questions
What if my photo cannot reach 100 KB?
If the target cannot be reached by lowering quality alone, the tool reduces the dimensions of the image step by step until it fits — this is automatic.
Can I choose a different size, like 50 KB or 20 KB?
Yes. Use the presets or type any target in kilobytes; the same search works for any limit.
Is it safe for ID or document photos?
Yes. Your photo is processed locally in your browser and never uploaded, which makes it ideal for sensitive documents.
