How do I reduce PDF file size?
Upload PDF, choose compression level (Web, Office, or Print), click Compress. Images are optimized while text stays sharp.
Will PDF compression affect text quality?
No. Only embedded images are recompressed. Text and vector graphics (logos, diagrams) remain perfectly sharp.
How much smaller will my PDF be after compression?
Typically 20-80% smaller depending on image content. Scanned documents and photo-heavy PDFs see the largest reductions.
What do the compression presets mean?
Web (72 DPI) for email/web sharing. Office (144 DPI) for screen viewing. Print (300 DPI) for professional printing.
Why did my PDF get larger after compression?
Rare case: if original images were highly optimized, recompression may add overhead. Try a lower quality setting.
What happens to transparent images during compression?
Transparency is flattened to white background for maximum compression. Images are converted to JPEG format.
Can I compress a password-protected PDF?
Yes. Enter the password when prompted. The output PDF will not have password protection.
Is PDF compression lossless?
Text is lossless. Images use lossy JPEG compression for smaller files. Higher quality presets have less visible compression.
