Limitations and quality checks

Compression may reduce image quality and may not shrink already-optimized PDFs much. Keep the original. Supported formats, processing limits, and output quality depend on the controls and services available on this page. If an operation fails, try a small supported sample and read any error message rather than assuming the file was processed.
