The Size Limits You're Probably Compressing For
Upload size limits by portal
Almost nobody compresses a PDF for fun — there's a portal or inbox rejecting your file. These are the upload limits we see people fighting most often:
| Where you're uploading | Limit | Tip |
|---|---|---|
| SECP eServices | 2 MB | Medium compression handles most scanned company documents |
| NADRA portals | 1–2 MB | Use high compression for multi-page scans |
| FBR IRIS e-filing | 5 MB | Roomier — medium keeps receipts crisp |
| HEC document upload | 2 MB | Degree scans usually need high compression |
| University admission portals | 1–2 MB typical | Check the exact limit; they vary by program |
| Email (Gmail) | 25 MB | Over that, compress or split the PDF |
| Email (Outlook) | 20 MB | Corporate servers often cap lower — 10 MB is safe |
| Job application portals | 1–5 MB | A compressed CV PDF also opens faster for recruiters |
What the three compression levels actually do
Text in a PDF is already tiny — what makes files huge is embedded images, especially scans. Low (144 DPI) and medium (108 DPI) resample those images to print-comfortable and screen-comfortable resolution respectively, while high (86 DPI) pushes for the smallest possible file. All three strip redundant metadata. Your text is never touched: it stays sharp, selectable and searchable at every level, which is why a text-only PDF barely shrinks while a scanned document can lose 80–90% of its size.
Choosing a level without trial and error
Start with medium — it lands under 2 MB for most scanned documents while staying comfortably readable on screen. Pick high only when a strict portal limit forces it, and check that stamps, seals and handwriting are still legible before submitting. Pick low when the PDF will be printed or contains fine detail like engineering drawings. If one oversized scan is the culprit, it can be faster to compress the image first and rebuild the PDF. Need to combine documents before uploading? Merge PDFs first, then compress the result once — and if the portal wants specific pages only, split the PDF instead of sending everything.
