PDF Compression FAQ

Is PDF compression lossless?

Our compression uses advanced algorithms that minimize quality loss. Low and medium compression levels maintain excellent quality, while high compression optimizes for file size.

What types of PDFs compress best?

PDFs with many images, scanned documents, and unoptimized content compress the most. Text-heavy PDFs may see smaller reductions but still benefit from optimization.

Is there a file size limit?

You can compress PDF files up to 50MB. Larger files may require splitting before compression or using our desktop solutions.
