Free Compress PDF
Compress one PDF or a whole batch with lossless, print, email, target-size, grayscale, or fully custom controls. Your upload uses encrypted durable storage when available and a private same-origin processor otherwise. Temporary sources are deleted after each attempt; durable checked results remain recoverable in this browser for up to six hours.

Short-lived by design
This tool uses open-source processors in a private temporary workspace that is deleted after each attempt. When durable storage is available, uploads are encrypted and resumable and checked results stay recoverable to this browser for up to six hours. If that storage is unavailable, the same-origin fallback returns the checked result directly. Failed or cancelled job files are removed immediately. Account storage is used only when you explicitly choose Save to Bookify.
