Guide · Compress PDF
Compress a PDF to send it by email
Gmail limits attachments to 25 MB, and many work mail servers set lower limits. Compressing a PDF often brings it under the limit without resorting to a file transfer service. PDFly's compression works best on scans and image-heavy PDFs.
Steps
- 1
Drop the heavy PDF into PDFly's Compress PDF tool.
- 2
Choose a level: Light keeps the best quality, Standard is a good balance, Strong gives the smallest file.
- 3
Click Run. PDFly shows the size before and after, and the percentage saved.
- 4
Download the result. Each page is turned into an image during compression, so text can no longer be selected: keep the original for editing.
