Frequently Asked Questions
Splitting cuts a single PDF file into multiple separate documents based on page marks or custom ranges (for example, splitting a 10-page document into two 5-page PDFs). Extracting pulls selected pages from the document and saves them as a new individual file, leaving the original file unchanged.
Yes, completely safe. Unlike other websites that upload your files to external servers, ToolZeno does all processing locally inside your web browser using HTML5 Web Workers and pdf-lib. Your documents are never uploaded, keeping your private legal, financial, or personal records entirely secure on your own device.
There is no hard limit on the file size or number of pages. However, because operations run inside your browser's memory sandbox, documents larger than 500MB or files with thousands of pages may trigger warnings about browser memory limits. We recommend processing extremely large documents in chunks for maximum stability.
We support standard syntax: use hyphens for ranges (e.g., '1-5') and commas or semicolons to separate different output files (e.g., '1-5, 6-10'). To extract scattered pages into a single document, specify page list values (e.g., '1, 3, 5, 10-12').
Yes. Once the split operation is complete, a list of all generated documents is displayed. You can click the edit icon next to any file's name to customize it before downloading, or click 'Download All as ZIP' to download them in a single archive.
