Compress PDF

Reduces the file size of a PDF while preserving its content and formatting. Compress always targets the smallest output; to trade size against quality, use Optimize PDF and its profile.

Example Zap

Compress every PDF added to a Dropbox folder and file the smaller copy elsewhere.

Dropbox — New File in Folder

Watch an /inbox folder.

Filter by Zapier

Only continue if the file name ends with .pdf.

Nitro PDF Services — Compress PDF

PDF File → the trigger’s file.
Output Type → Download file.

Dropbox — Upload File

File → Compressed PDF File.
Folder → /compressed, not the folder the trigger watches.

Uploading back into the trigger’s own folder will loop. Use a different folder or filter the Zap’s own output out.
