Are my JPG pictures uploaded anywhere?

Pictures up to 200 MB never leave your device: ConvertKitty converts them inside your browser, with ImageMagick compiled to WebAssembly. Only larger files, or formats your browser cannot handle (camera RAW, PostScript, XPS, LibreOffice and Publisher files, and video or audio), are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.

Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.

Can I change the size or quality of the AVIF?

Can I convert several JPG files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
