Frequently Asked Questions

Everything you need to know about processing files with this tool.

Can any image be compressed to 5KB?▾

Yes, though very high-resolution images may show visible quality reduction at such small sizes. We recommend starting with images under 2MB for best results.

How does target-size compression work?▾

We iteratively reduce quality and/or resolution until the file size is at or below your target, finding the optimal balance automatically.
