FAQ
Can I target a specific file size?
Yes. Switch to target-size mode, enter a KB value, and the tool searches for the closest quality that stays under that size.
Is the preview the actual output?
Yes. The preview uses the same encoded file that is downloaded, so the size and quality you see are real.
Are images uploaded anywhere?
No. Compression and preview generation happen locally in your browser.
