Splitting a PDF with a server tool means uploading the entire document — every page, including ones you don't need. ModernPDF extracts pages locally, so the full document never...
Open Split PDFExtract the pages you need without exposing your entire document to a third party.
Even pages you don't extract never leave your device. Server tools see every page — we see none.
Check the Network tab: zero outbound file data during the split operation.
No upload time for the full document. Page extraction happens locally in under a second.
Your PDF loads into browser memory. All pages available for preview — none transmitted.
Choose a range, individual pages, or split into single-page files. Preview before confirming.
Extracted pages assemble into a new PDF locally. The full original remains only on your device.
When splitting a PDF, you want a subset. But server tools require the complete file. A 100-page medical record uploads so you can extract one lab report.
Pages you don't need — and wouldn't voluntarily share — are transmitted alongside pages you do need. This is an inherent flaw of server architecture.
ModernPDF processes the split in your browser. The full document loads locally, selected pages are extracted, and a new file is created. Pages you didn't select never exist outside your device.
There is no server. Loading, selecting, extracting, and assembling all run in your browser. No part of the document is ever transmitted.
Yes. Since absolutely no document data leaves your device at any point during the split operation, attorney-client privilege and document confidentiality are fully maintained. The complete filing remains on your computer throughout, and only you can see all pages during the extraction process.
Free users can split files up to 10MB in size. Pro subscribers can process files up to 500MB, which covers even the largest legal document compilations and multi-hundred-page filings. The WebAssembly engine processes large files efficiently using your device's available memory and processing power.
Yes. Extract the pages you need from each source document, then combine them into a single file using Merge them. Both the split and merge operations run entirely in your browser with zero server involvement, so even this multi-step workflow keeps every document completely local on your device.
Yes. Extracted pages are identical to originals — all formatting, embedded fonts, images at their original resolution, interactive form fields, annotations, and bookmark links are preserved exactly as they appear in the source. No reprocessing or recompression occurs.
