Why Won't My PDF Upload? File Size Limits Explained

Typical Upload Limits

Gmail limits attachments to 25 MB, job portals typically allow 5-10 MB, and government sites vary from 2-10 MB. Knowing the limit helps you plan your compression.

How to Check Your PDF's Current Size

Right-click the file and select Properties, or check the file size in your browser's download bar. Compare this against the upload limit.

How to Shrink a PDF to Meet Requirements

Use an online compressor to reduce file size. Most tools let you choose between quality and compression level. For strict limits, use maximum compression.

Splitting Large PDFs as an Alternative

If compression isn't enough, split the PDF into smaller files. Upload each part separately or combine them after reducing individual page sizes.
