PdfCrunch

Drop a PDF here or click to choose a file Shrink a PDF and strip its hidden metadata. Text, fonts, links and bookmarks stay intact. Runs entirely in your browser: the file never leaves this tab.

Settings

Advanced

Images Image fidelity JPEG quality Max image size Convert lossless images to JPEG (when the result meets the fidelity target and is clearly smaller than a lossless re-encode) Convert CMYK images to RGB (much smaller; looks the same on screen, but print colours and pure-black text may shift)

Vectors & structure Precision Rounds line and curve coordinates; text is never touched. Merge duplicate images/fonts

Security

Strips content that can run code, reach out over the network, or carry hidden data. Everything is removed by default.
