Frequently Asked Questions (FAQs)
Will compressing a PDF reduce its quality?
Yes, compression can reduce quality — especially for images — depending on the compression level you choose.
How much can I compress a PDF without losing too much quality?
It depends on content: text‑heavy PDFs compress less aggressively, but image‑heavy ones can be reduced significantly while preserving readability.
What are the different compression settings (high, medium, low) used for?
High compression gives the smallest file size with more quality loss; medium balances size and quality; low preserves quality but reduces size less.
Can I compress a PDF to a specific file size, like 100 KB or 1 MB?
Many tools allow target size compression, but how small you can go depends on the original content, resolution, and embedded elements.
Is PDF compression safe for confidential or important documents?
Yes — compression doesn’t inherently make a PDF less secure — but be careful with tools and ensure they don’t store your files.
What is the difference between lossless and lossy PDF compression?
Lossless compression preserves image/text quality but gives smaller reduction; lossy compression reduces size more but sacrifices some quality. :contentReference[oaicite:0]{index=0}
Why is my PDF still large even after compression?
If your PDF has very high-res images, embedded fonts, or already optimized content, further compression may not greatly reduce size. :contentReference[oaicite:1]{index=1}
