How to compress a PDF for email / government portals
Many email systems block attachments above 25 MB; Indian government portals (UIDAI, GST, PAN, RTI, court e-filing) often demand even tighter ceilings of 5 MB or 2 MB. Our compress tool re-rasterises each page at a chosen DPI and JPEG quality, then rebuilds a fresh PDF. The result is a dramatically smaller file with predictable, controllable quality.
Quick steps
- Drop the PDF into the box above.
- Pick a preset. Balanced is the right default; switch to Maximum only if you absolutely must hit a tight size cap.
- Click Compress & Download. The new file replaces the old one in your workflow.
Frequently asked questions
How much smaller can I expect the file?
Heavily image-based PDFs (scans, photo bundles) often shrink 60-85% on the Maximum setting. Text-heavy PDFs already use clever compression internally, so savings may be modest.
Does compression hurt text readability?
On the Balanced and High presets, text remains crisp on screen and print. The Maximum setting can introduce slight blur on very small fonts; use it only when file-size limits are strict.
Will the compressed PDF still have selectable text?
Our current compressor re-rasterises pages to images for predictable file size — so text is no longer individually selectable. If you need selectable text, use a smaller compression preset and consider re-saving the PDF with a tool like Acrobat that performs lossless object-stream optimisation.
How do I compress without losing quality?
For lossless-feel results, use the High preset and ensure the source PDF's images are not already heavily compressed. Read our in-depth guide for tactics like image-resampling and font-subsetting.
