Frequently asked questions
How much can I reduce my PDF file size?
Results depend on the original content. PDFs with many images typically shrink by 40–70%. Text-heavy PDFs may reduce by 10–30%. If compression would make the file larger, we return the original.
Will compressing a PDF reduce its quality?
We use Ghostscript's "ebook" preset, which optimises file size while keeping text sharp and images at a quality suitable for screens and email. For print purposes, the original is recommended.
Is there a file size limit for PDF compression?
Yes, files up to 50 MB can be compressed. If your PDF is larger, try splitting it first.
Is compressed PDF safe to share?
Yes. The compression only affects image resolution and embedded metadata — the document content and text remain identical.
Can I compress a PDF under 200 KB for an Indian government portal?
Yes. Many Indian government portals (UPSC, SSC, state PSC sites, university applications) cap PDF uploads at 100–500 KB. Our "ebook" compression usually brings a 2–5 MB scanned PDF down under 200 KB while keeping text readable. If the result is still too large, try splitting the PDF first and compressing only the pages you need.
How do I compress a PDF under 100 KB for UPSC or scholarship forms?
For the strictest 100 KB cap (UPSC photo / signature uploads, some scholarship sites), first crop the PDF to only the page you need (use Split PDF), then compress. A single-page scan at A4 usually lands between 80–150 KB after our "ebook" compression. If it's still over 100 KB, lower the source scan resolution to 200 dpi before scanning and try again.
