Frequently Asked Questions

How do I compress a photo to exactly 100 KB?

Upload your image — Target-size mode is already set to 100 KB — and click Compress. The tool automatically tunes the quality to stay within 100 KB.

Are my files uploaded to a server?

No. Compression happens entirely in your browser; your files never leave your device.

What if 100 KB can't be reached without heavy quality loss?

For very small targets the tool will, if needed, also reduce the resolution to reach 100 KB, and it tells you when it does.

Is it free and watermark-free?

Yes — free, no signup and no watermark. You can process up to 20 files and download a ZIP.
