Frequently Asked Questions
What PDF operations are supported?
Five operations: Merge (combine multiple PDFs into one), Split (extract pages by range or split each page), Compress (reduce file size via rasterization), To Images (export each page as PNG/JPG), and Page Manage (rotate or delete specific pages).
Are my PDFs uploaded to a server?
No. All PDF processing happens entirely in your browser using pdf-lib and pdf.js libraries. Your files never leave your device, ensuring complete privacy and security.
How does PDF compression work?
Compression uses rasterization: each page is rendered as an image using pdf.js, then a new PDF is created with those images using pdf-lib. This reduces file size for image-heavy PDFs but makes text non-selectable. Choose High compression for smallest files or Low for better quality.
Can I reorder pages when merging?
Yes! After selecting multiple PDF files for merging, use the up/down arrow buttons next to each file to reorder them. The merged PDF will follow the order shown in the list.
What is the page range syntax?
Use commas to separate individual pages and ranges. For example: "1-3, 5, 8-10" extracts pages 1, 2, 3, 5, 8, 9, 10. Page numbering starts at 1. This syntax works for both Split and Page Manage features.
Is there a file size limit?
There's no hard limit, but very large PDFs may take longer to process and use more memory. For best performance, we recommend PDFs under 100MB. The compression and to-images features process pages sequentially to manage memory usage.
