Is the JPG to WebP conversion free?

Yes. Atlas Convert is completely free, no account needed, no watermarks, no ads.

Are my files uploaded to a server?

Most conversions run entirely in your browser using WebAssembly (ffmpeg.wasm, fflate, canvas). Only when a conversion genuinely requires server-side software (for example PDF↔DOCX or WMV target) is the file sent to our backend, processed in an ephemeral temporary directory, and deleted within seconds.

What does WebP look like compared to JPG?

Atlas Convert preserves the content faithfully when converting from JPG to WebP, but the underlying capabilities of each format differ — for example, format-specific features such as transparency, animation, vector data, or document layout may behave differently in the output.
