Why PDF files get too large
Scanned contracts, phone photos of documents, and slide decks exported as PDF often carry multi-megapixel JPEGs on every page. Email gateways reject 10–25 MB attachments. LMS and government portals cap uploads. Desktop Acrobat is overkill when you only need a smaller copy for one send.
The free PDF Compress tool on Fah Swe Tools re-encodes pages with quality presets so you can trade a little sharpness for a much smaller file — then download and keep the result locally. Uploads auto-delete within 24 hours.
How to compress a PDF online
- Open Compress PDF.
- Upload a PDF (up to 40 pages).
- Choose High (larger, sharper), Medium (balanced), or Low (smallest).
- Run the tool and download the result.
- Open the file once to confirm readability before you email it.
Encrypted / password-protected PDFs are rejected for safety.
When compression helps most
- Scanned paperwork and ID packs
- Phone-photo PDFs from “scan” apps
- Image-heavy reports and proposals
Text-only PDFs that are already optimized may not shrink. In that case we keep the original size and tell you honestly — try Low if size still matters more than crispness.
Quality trade-offs (be honest with stakeholders)
Compression rasterizes pages as JPEG images. Selectable text and vector sharpness are reduced. Use High when a client will zoom; use Low for “just get it through the email gate.” For merge/split without re-encoding, use Merge PDF or Split PDF instead.
Workflow tips
- Compress after you finalize content so you do not re-compress repeatedly.
- If source images are huge, optimize them with Compress Image before building the PDF.
- Split appendices with Split PDF when a single attachment still exceeds limits.
