Reduce PDF Size for Email Attachments
Check the mail error and the total size of all attachments. Compress the PDF where useful, then replace the old attachment with the result you have inspected.
Check the actual mail limit
Your sender, recipient, and organization may have different rules. Follow the current service message or account policy rather than assuming one limit applies to every email.
When several files are attached, add their sizes together. A small PDF may still be part of an oversized message.
Try compression and check important pages
Keep the original. Open the PDF compressor, choose a level, and compare sizes. Check amounts, signatures, dates, and small tables in the downloaded file.
If the PDF does not get smaller, the tool makes the original available. For a different level, reset or re-add the original PDF.
Replace the old attachment
Remove the original attachment from your draft and attach the checked download. Confirm its filename and size before sending. Kompres does not send email or replace attachments for you.
If the message is still too large
Review other attachments as well. If the recipient allows it, use an appropriately shared link or another agreed delivery method. Do not assume a link is suitable when an attached file is required.
Kompres does not upload files to a cloud drive or generate a sharing link in the current workflow.
