Compress PDF

Choose a mode and compress your PDF. Swiss-hosted. Files are processed temporarily on our Swiss server and deleted after the response. No ads. No third-party tracking. (No preview.)

Compress PDF (Mode A or Mode B)

Mode A: prune unused resources, keep quality (no forced image downsampling).
Mode B: Mode A + shrink only large pages (for example above 25MB) using stronger settings.

Tip: If you started a long job by accident, click Cancel. It will stop the server-side job.

Output PDF filename

Used if the backend returns a PDF.

Output ZIP filename (optional)

Modes

Mode A is best if your PDF got bloated by splitting or contains shared resources copied into pages.
Mode B reduces size more aggressively only on large pages (quality trade-off there).
Files are uploaded for processing and deleted after the response.

Privacy and processing

Compress PDF runs on Bulletproof PDF's privacy-first backend. Your file is uploaded for processing, the result is returned, and the upload is deleted after the response. No ads, no analytics.
