Quality, compatibility and file limits

Raster export can flatten layers and reduce color depth; source editing data is not preserved.

Processing uses your device when possible and our servers when required. Browser files are limited to 256 MB each; server conversions to 64 MB; browser spreadsheets to 32 MB. Previews show supported content and do not guarantee identical rendering in every application.
