What is compress pdf?
PDF files often contain high-resolution images that balloon file size - making them slow to email, upload, or share. PixlUtils compresses PDFs by re-rendering each page at your chosen quality level and recompressing embedded images. Choose Screen for the smallest file, Web for balanced quality, or Print for high-fidelity output. All processing runs in your browser with no upload. Free forever.

💡 Pro Tips
Use Screen preset for email attachments
Screen quality renders at ~72 DPI - enough for reading on screen and significantly smaller than Web or Print. Perfect for email.
Web preset is the sweet spot
Web quality (~150 DPI) cuts file size substantially while keeping text and images readable - great for online sharing and uploads.
Compress before merging for smallest result
Compressing each PDF individually before merging them produces a smaller combined file than merging first.
Unlock encrypted PDFs first
If your PDF is password-protected, use the Unlock PDF tool to remove the password before compressing.
