Frequently asked questions

Why do email providers reject my PDF?

Most providers cap attachments around 20-25MB. Compressing images inside the PDF usually brings it under the limit without touching text.

What if it is still too big?

Split the PDF by size into smaller chunks and send them across multiple emails — or share via a link instead.

Will the recipient see lower quality?

Light compression keeps text pixel-sharp; only large photos soften slightly. For forms and contracts the difference is invisible.
