Compress PDF for Email

Reduce a PDF attachment before sending documents, scans, invoices or forms by email.

How to use

  1. Upload the PDF to the compressor.
  2. Choose a compression level suitable for email.
  3. Download and review the result.
  4. If needed, split the document into smaller parts.

Why email rejects PDFs

Mailboxes and contact forms often limit attachment size. A scanned PDF can become large quickly because each page may contain a high-resolution image.

Recommended workflow

Compress the PDF first. If the result is still too large, split the document or convert only the pages that must be sent.

Before sending

Open the result and check readability. Strong compression can reduce image quality, especially in scanned documents.

FAQ

Will compression change the text?
Text usually stays selectable when the source PDF contains text. Scanned pages may lose image detail with stronger compression.
What size is good for email?
Many email systems handle a few megabytes comfortably, but each mailbox has its own limit.
What if the file is still too large?
Split the PDF or remove pages that are not needed for the message.
