Frequently Asked Questions

How do I reduce image KB?

Pick your target size from the links above, upload your image, and the tool automatically adjusts quality and dimensions until the file fits.

Why do forms require a specific KB size?

Strict limits keep server storage and bandwidth low, and standard sizes make processing automated forms easier.

Will reducing KB ruin my photo?

No — most photos can drop to 100KB or less with no visible difference on screen. Use the largest target that meets the requirement.

Is this really private?

Yes. Every tool runs locally in your browser, so nothing is uploaded or stored.
