Questions about Compress PDF
Frequently asked technical and operational questions about compress pdf.
Will compressing a PDF degrade body text quality?
No. Vector text characters and font glyphs are preserved losslessly. Compression targets embedded raster images, downsampling DPI and removing redundant stream dictionaries.
How do I reach strict file limits for online portals?
Choose Recommended or Extreme compression. For scanned paperwork, converting to grayscale first often yields substantial additional size reduction.
Where does Compress PDF process my input?
Processing executes inside an isolated container with zero permanent data retention. Temporary files are scheduled for automatic physical deletion within 30 minutes.
