How to send large print-ready PDFs
Export to the PDF/X standard your printer asks for, then send it as a transfer link. Print PDFs embed every font and full-resolution image, so they are often far past the 20 to 35 MB an email takes, and a compressed copy is not what the press needs.
The limits, in numbers

How to send it
- 1Ask the printer which PDF/X standard and bleed they want, and export with exactly that preset.
- 2Drop the PDF on yungle.co; it is sent as it is, not recompressed.
- 3Send the link to the print shop’s email. You can see when it has been downloaded.
Questions, answered.
Ask us something elseWhich PDF/X should I choose?
The one your printer asks for. PDF/X-1a is the most widely accepted and flattens transparency; PDF/X-4 keeps live transparency and is the modern default where the printer supports it.
Can I compress the PDF to email it?
Compressing lowers image quality, which shows in print. Keep the full-quality file and send a link instead.
Will the file be changed in transit?
No. A Yungle transfer delivers the exact file you uploaded, byte for byte.
