Questions
Are my images uploaded anywhere?
No. Everything runs in your browser using the Canvas API — the file never leaves your machine, and the tool keeps working if you go offline after the page loads. There is no account, no queue, and no server-side copy to delete later.
Will converting to WebP lose quality?
WebP is a lossy format, so some data is discarded. At 90% quality the difference is invisible for screenshots and UI images. Drop to 70–80% only if file size matters more than crisp text — compression artefacts show up around lettering first.
