What this converter actually supports
Published still-image routes use the deployed ImageMagick and Ghostscript toolchain, with dedicated workflows for animation, camera RAW rendering, SVG tracing, and selected modern formats where the generic path is not sufficient.
Use JPG for widest compatibility, PNG when transparency matters, or WebP for another web-focused compressed output.
The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.
