Frequently asked questions
Are my images uploaded?
No. They are read and re-encoded locally with the Canvas API and never sent to a server.
Which format should I choose?
WebP is the best all-round modern choice; keep JPEG for photos if you need maximum compatibility, and PNG only for graphics needing lossless transparency.
Why not just scale images in HTML?
Because the full-size file is still downloaded. Compressing and resizing the actual file is what makes pages faster.
