1. Find the actual upload limit
Before compressing anything, check the portal requirement. A 5 MB PDF does not need to become 500 KB if the limit is 4 MB.
2. Remove pages you do not need
Blank pages, instructions, duplicated scans, and unnecessary attachments add size. If the portal does not require them, removing them is often the cleanest reduction.

Remove PDF pages →3. Compress the PDF
Compression can reduce image resolution and eliminate unnecessary document data. Image-heavy scans usually shrink more than text-heavy documents.
4. Aim below the limit
Leave a little safety margin. If the maximum is 2 MB, a result around 1.8 or 1.9 MB is safer than landing on the exact boundary.
5. Check readability before uploading
Zoom in on signatures, ID numbers, stamps, and small text. Over-compression can make a technically smaller file practically useless.

Reduce PDF size locally and keep control of the result.
Compress my PDF →FAQ
How can I make a PDF smaller?
Remove unnecessary pages, compress embedded images and document data, and target the actual upload limit rather than compressing blindly.
Will making a PDF smaller reduce quality?
It can, especially when images are compressed heavily. The goal is to balance readability with the required file-size limit.
Should I compress a PDF as much as possible?
No. Compress only enough to meet the receiving portal’s requirement while preserving legibility.
