How to Reduce PDF File Size for Email Attachments
Step-by-step guide to compressing PDFs under 25MB for Gmail, Outlook, and Yahoo. Includes quality settings comparison.
// Why email providers limit attachment sizes
Most email providers cap attachments at 25MB (Gmail, Outlook) or even less. When your PDF exceeds this limit, you need to compress it before sending. PDFBaba's compression tool lets you shrink files by up to 80% without losing readability.
// Step-by-step: Compress a PDF for email
Open PDFBaba's Compress PDF tool. Upload your file. Choose 'Balanced' for a good size-to-quality ratio. Click Compress and download the smaller file. If it's still too large, try 'Strong' compression.
// Quality settings explained
Minimal compression keeps the file nearly identical to the original. Balanced is recommended for most emails — it reduces image DPI to ~150 while keeping text sharp. Strong compression targets 72 DPI, which is fine for on-screen reading but may look blurry in print.
