Questions
How do I compress a passport photo to 100 KB?
Pick your file, set the target to 100 KB and press Compress. The tool lowers quality first, then dimensions if needed, and stops at the best result at or under 100 KB.
What is 1 KB?
1 KB here is 1,024 bytes, the same unit most upload forms use.
Which formats work?
Input: JPG, PNG and WebP. Output: JPEG, WebP or PNG.
Is my image uploaded anywhere?
No. Compression runs in your browser. The file never leaves your device.
Will the result be exactly the target size?
No. Photo KB gives a file at or under your target, usually within about 10% of it. If a target cannot be reached, it says so and shows the best result.
Why does the quality drop?
JPEG and WebP shrink by discarding detail. Photo KB uses the highest quality that still fits your limit before it reduces dimensions.
What is in Pro?
A one-time $12 purchase unlocks batch compression of up to 50 images with ZIP download, portal presets and pixel-size boxes in the Chrome extension.
