Private local PDF compression

PDFine lets you compress PDFs directly in your browser. For this route you do not need an account and, when the PWA is loaded, the work runs on your device without uploading the PDF to PDFine servers for editing.

Open PDFine and choose Compress PDF Enter the app, open your PDF, and select the Compress PDF tool.

When to use it

• When a PDF is too large for email, chat, or a form upload.
• When you want quick compression without installing a desktop app.
• When you prefer to keep the document on your device whenever the tool allows it.

Privacy and limits

Compression is local, but it may convert pages into images to reduce size. If selectable text or exact fidelity matters, review the output before sharing it.

On iPhone, iPad, or low-memory devices, large PDFs may take longer or require defensive limits.
