FAQ

Are my images uploaded to a server?
No. All compression happens entirely in your browser using the Canvas API. Your images never leave your device.
What input formats are supported?
JPG, PNG, and WebP. Output can be JPEG or WebP with adjustable quality.
Is there a file size limit?
Since processing runs in your browser, very large files may slow down your browser. For typical web images, there's no practical limit.
Can I compress multiple images at once?
Yes! Select multiple files at once or upload in batches. All compressed results can be downloaded together.
JPEG or WebP — which should I choose?
WebP typically achieves better compression at similar quality. JPEG has broader compatibility with older browsers and tools.
