Shrink PDF file size without visibly losing quality. Great for emailing (Gmail's 25 MB cap), uploading to slow portals, or archiving a decade of documents. We use Ghostscript with the /ebook preset — images are downsampled to 150 DPI, fonts subset, and unused objects removed, typically cutting the size by 40–80%.
Common ways to use Compress PDF
Email large reports
Send a 40 MB report through Gmail by shrinking it to under 25 MB.
Upload to gov portals
Government e-filing sites often cap uploads at 5–10 MB — Compress PDF gets you under the limit.
Store a decade of scans
Reduce the storage footprint of your document archive by up to 80%.
Web-friendly PDFs
Landing-page PDFs load faster and rank better when they're small.
Print by email
Some networked printers reject huge PDFs — shrink first.
Compress PDF — frequently asked questions
How much smaller will it get?
Typically 40–80% smaller depending on how many images the PDF contains. Text-only PDFs shrink less; image-heavy scans shrink the most.
Will quality drop?
The /ebook preset keeps images sharp enough for on-screen reading. For premium print use Compress in a paid tool with lossless mode.
Is the compressed file still searchable?
Yes — text stays as text; only images are downsampled.
What if the PDF is already small?
The output might be similar in size or even slightly larger. That's normal — the file was already well-compressed.
Are annotations kept?
Yes. Bookmarks, comments and form fields survive compression.
