Questions
Are my files uploaded?
No. The page loads its code once, then reads and processes your files inside the browser tab. Nothing is sent to a server; you can confirm it in your browser's network panel while a file converts.
Which format should I pick?
JPG for photos that must open anywhere, PNG for screenshots, graphics and transparency, WebP for the smallest files on websites.
Can it convert to AVIF or HEIC?
No. Browsers cannot encode those formats from a canvas, so they would need large bundled encoders. Both are planned only if there is demand.
