What to do when a PDF is still too big
You ran the compressor, chose the strongest level, and the file is still over the limit. That is not a dead end — it just means the problem is now length, not weight. Here is the order to attack it in.

1. Send fewer pages
The single most effective move. Application forms rarely need your entire bank statement — they need the pages showing your address or salary. Extract the required pages and compress just those. Ten pages compress to a fraction of what a hundred do.
2. Split and send in parts
Many portals accept multiple files per submission even when they cap each file's size. Split the document into logical parts — chapter 1, chapter 2 — compress each, and upload them as separate files. Check the portal's rules first; some insist on a single file.
3. Rebuild the worst pages
If one or two pages carry full-page photographs, they dominate the file size. Convert those pages to JPGs, compress the images hard, and rebuild the PDF from the lighter versions. A page that was 8 MB of photograph can become 300 KB with no meaningful loss for a document scan.
4. Change the delivery method
- Email: above 20-25 MB, send a cloud link (Drive, OneDrive, iCloud) instead of an attachment.
- Upload forms with a hard cap: contact the organisation — many have an alternative route.
- Never re-compress an already compressed file; quality drops and size barely moves.
Step by step
- 1Confirm the actual limit and how far over it you are.
- 2Extract only the pages that are genuinely required.
- 3Compress the extracted file at medium, then strong if needed.
- 4If it is still over, split into parts and compress each part.
- 5As a last resort, deliver by link rather than attachment.
Frequently asked questions
- Why won't it get any smaller?
- Compression removes redundant image data. Once that is gone, the remaining size is real content — pages. Only removing pages or splitting reduces it further.
- Is zipping the PDF worth trying?
- No. PDFs are already compressed containers; a zip typically saves 1-3% and some upload forms reject zip files anyway.
