Frequently Asked Questions

Is it safe to use this PDF tool?

Yes. All PDF processing happens entirely in your browser using JavaScript. Your files are never uploaded to any server, so your documents remain completely private and secure. You can verify this by disconnecting from the internet -- the tool still works.

How do I split a PDF into separate pages?

Upload your PDF using the Split tab, then enter page ranges like "1-3, 5, 7-10". Each comma-separated range creates a separate output file. For example, "1-3, 5" produces two files: one with pages 1-3 and another with page 5. Click "Split PDF" and download the results.

Can I merge more than two PDF files?

Yes. The Merge tab lets you add as many PDF files as you need. You can reorder them using the up and down arrows to control the final page order before merging them into a single document.

Does compressing a PDF reduce its quality?

No. The compression works by stripping unnecessary metadata and rebuilding the document structure. It does not re-encode images, so visual quality is preserved. The amount of size reduction depends on how much metadata and unused objects the original PDF contains.

What is the maximum file size I can process?

Since processing happens in your browser, the limit depends on your device's available memory. Most modern devices can handle PDFs up to 100 MB without issues. For very large files, close other browser tabs to free up memory.
