Large business presentations, architectural drawings, marketing lookbooks, tender dossiers, and financial annual reports frequently balloon to 25MB, 50MB, or even 100MB due to embedded high-resolution graphics and uncompressed background images. Attempting to send these files via email routinely triggers bounce-back errors such as 'Attachment exceeds server limit' or 'Message size too large', halting critical business communication.

Frequently Asked Questions
Can I compress a 50MB or 100MB PDF document down to under 5MB?
Yes! The 5MB preset applies intelligent dynamic downsampling to high-resolution photographic layers and embedded presentation slides, significantly reducing multi-megabyte graphics while preserving sharp vector text, logos, and charts.
Why do email providers reject PDF files over 5MB to 10MB?
While standard consumer email services like Gmail support up to 25MB attachments, corporate firewalls, enterprise Microsoft Exchange servers, and government mail relays frequently restrict incoming attachment sizes to 5MB or 10MB to prevent mailbox quota flooding and ensure rapid transmission.
Will my graphs, financial tables, and architecture plans remain clear?
Yes. Our engine differentiates between vector typography/diagrams and photographic raster textures. Architectural schematics, CAD exports, Excel financial tables, and vector curves remain crisp at any zoom level, while heavy image backgrounds are optimized.
Is there any limit on the number of pages or file uploads?
No. You can compress multi-page PDF reports, architectural blueprints, sales catalogs, and corporate annual reviews with unlimited uses, no credit card, and no registration required.
