Merge & Split PDF
Merge PDFs in order, extract a page range, or split every page into its own file - locally, without uploads.
Merging three scans into one submission PDF, pulling chapter five out of a hundred-page report, splitting a contract page by page for filing - PDF merging and splitting are the most frequent document operations, yet they constantly get funneled into services with daily limits or watermarks. This tool does both with an in-browser PDF engine: files never touch the network, there is no page cap, and no watermark.
Merge mode accepts multiple PDFs and lets you reorder them; split mode understands ranges like "1-3,5,8-", and can split every page into its own PDF bundled as a ZIP. The output filename is yours to choose, and page counts are shown as you go.
How merging works - and why quality never suffers
Merging copies each source document's page objects into a new file as-is: vectors, fonts and images are not re-encoded, so output quality is bit-identical to the source. What does not survive is document-level structure: bookmarks and form fields generally do not carry across merged files, while links embedded in page content do.
How to write a page range
Ranges are comma-separated and freely mixed: "1-3,5" takes pages 1 through 3 plus page 5; "8-" runs from page 8 to the end; "-4" takes the beginning through page 4. The per-page split mode honors the same range - only selected pages get split into single-page files.
Which PDFs cannot be processed
Password-encrypted PDFs cannot be decrypted locally by a browser - remove the password first (open with the password, re-save without one). Digitally signed or permission-restricted documents will lose their signatures after processing - that is the security model working as intended. Corrupt or truncated files are reported at load time instead of producing broken output.
Frequently asked questions
- Are my documents uploaded?
- No. Merging and splitting run on an in-browser PDF engine with no upload path, which makes the tool suitable for contracts, ID scans and anything else that should not leave your machine.
- Is there a page or size limit?
- No artificial one. The practical ceiling is browser memory: documents of several hundred pages and tens of megabytes are routine; thousand-page monsters are better processed in chapter-sized batches.
- Can I control the merge order?
- Yes - every file in the list has move-up/move-down buttons. Files are concatenated strictly top to bottom, and page numbers renumber in that order.
- What are the split filenames?
- Per-page splits default to originalname-page.pdf, delivered inside one ZIP so you are not clicking through dozens of downloads; range extraction produces a single PDF whose filename you set.
