Compress PDF
Compress PDF for email without leaving the browser
This route is for the common deadline job: make the attachment small enough to send, keep it readable, and avoid a signup wall.
Why this route matters
- Shrink attachments before Gmail or Outlook blocks the send.
- Keep file size down without switching to a heavyweight PDF suite.
- Run the job in the browser so sensitive documents stay local.
Fast workflow
- Upload the PDF you need to send.
- Start with the default quality and check the output size.
- Drop to a lower setting only if the attachment still exceeds the email limit.
Frequently asked questions
What file size should I target for email?
Most email systems start failing around 20 to 25 MB once attachments and message overhead are included. It is safer to compress below that threshold.
Should I compress before or after merging PDFs?
Usually merge first and compress second. That gives you one final file to optimize for sending.
What if the compressed file is still too large?
Use a lower quality setting or split the file into parts if the recipient can accept multiple attachments.
