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 a camera-specific format page when known, or supply dimensions and pixel details in specialist software for headerless data.
The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.
