Upload PDF tips

📤

Many government and business portals limit uploads to 5–10 MB. Compress beforehand rather than getting rejected at the last step.

⚡

Uploading a 50 MB PDF takes minutes. Compressing it to 5 MB saves you time on every single upload.

📋

Online job applications, visa forms, and university portals all have PDF size limits. Pre-compression avoids the frustration.

💡

Test after compression — open the file and verify all pages, forms, and fonts look correct before submitting.
