Frequently Asked Questions
What is the recommended PDF attachment size limit for corporate emails?
While public services like Gmail and Yahoo allow up to 25MB attachments, many corporate firewalls, Outlook servers, and recipient mailboxes reject emails over 5MB or 10MB. Keeping attachments under 2MB ensures universal delivery.
How does PDFZento shrink large multi-page scans so effectively?
It detects scanned raster pages, converts heavy TIFF/BMP streams into optimized DCT compression, strips unneeded alpha channels, and downsamples excess scan DPI to an optimal 150 DPI reading resolution.
Can I compress a 30-page or 50-page scanned document?
Yes. PDFZento can process large documents directly in your browser without arbitrary page limits.
