No file size restrictionsFrequently Asked Questions
Are my PDF files uploaded to a server?
No. All merging and splitting happens entirely client-side inside your browser using advanced JavaScript libraries. Your files remain 100% private.
Is there a limit on file size or number of pages?
There are no artificial limits imposed by us. You can merge large PDFs or split multi-hundred page documents based on your device's available memory.
How do the different split methods work?
Extract All Pages: Automatically separates your entire document so that every single page becomes its own individual PDF file.
Custom Ranges: You can specify individual pages or ranges separated by commas (e.g. 1-3, 5, 8-10). Each defined range or individual page will be exported as a distinct PDF file.
Visual Selection: Click on the page previews to select the pages you want to keep. The selected pages will be combined into a single, new PDF file.
How do I merge PDFs?
Select Merge mode, drop your PDFs, drag to reorder them, and click Merge. Your combined file downloads instantly.
Is Split & Merge really free?
Yes, 100% free forever. No watermarks, no sign-ups, no limits. Built with pdf-lib and runs offline in your browser.
