Frequently asked questions
Can I convert other formats to WebP here?
This tool optimizes existing WebP files. To convert JPG or PNG into WebP, use JPG to WebP or PNG to WebP.
How small can WebP go?
At quality 75 most photos land 25–35% below JPEG equivalents. Going below ~50 starts to show visible artifacts — check the preview before committing.
Is anything uploaded?
No. WebP compression happens entirely on your device — the file never leaves your browser.
