Overview
Compress PDF shrinks file size when attachments exceed limits or uploads time out. Compression may reduce image resolution inside the PDF, which is usually acceptable for email but not for print production.
Try moderate compression first and open the result to confirm text remains readable. For scans, quality loss may be more visible than for born-digital PDFs.
When compression is insufficient, consider splitting the document or removing embedded high-resolution images at the source.
How to choose
- Email attachment too large → Compress PDF.
Frequently asked questions
Will compression remove text?
Text generally remains, but embedded images may be downsampled.
Is there a server-side option?
Some deployments use a worker for heavier files. The tool page states where processing runs.
Can I compress multiple PDFs at once?
Compress PDF handles one file per run unless the UI explicitly supports batch mode.
