Why this merge & split tool

🔒 Private by design

Your PDFs are processed entirely in your browser and are never uploaded. Combine contracts or split scans without them leaving your device.

✨ Lossless output

No rasterization: text, fonts, vector graphics and images are copied verbatim. Merged and split files keep the exact quality of the originals.

📦 One-click ZIP

Split into dozens of files and get them all in a single ZIP. A split that yields one file downloads as a plain PDF instead.

How to merge or split a PDF

  1. Pick a mode. Merge combines many PDFs into one; Split breaks one PDF into several.
  2. Merge: drop in your PDFs, drag them into the right order, remove any you don't need, then click Merge. The summary shows the file count, total pages and combined size.
  3. Split: open a PDF and choose how — by custom ranges (e.g. 1-5, 6-12, 13-25), one file per page, fixed chunks of N pages, or extract a single range like 15-42.
  4. Download. A single result comes as a PDF; multiple results are bundled into a ZIP.

Frequently asked questions

How do I merge PDF files?
Switch to Merge, drop in two or more PDFs, drag them into the order you want, and click Merge. A single combined PDF is generated and downloaded. Pages are copied as-is, so quality is unchanged.
How do I split a PDF?
Switch to Split and open a PDF. Choose a mode: by custom ranges (e.g. 1-5, 6-12), one file per page, fixed chunks of N pages, or extract a single range. Multiple outputs are packed into a ZIP; a single output downloads as a PDF.
Is my PDF uploaded to a server?
No. Everything runs locally in your browser. Your files never leave your device, which makes the tool safe for confidential documents.
Will merging or splitting reduce quality?
No. Pages are copied between documents without rasterization — text, fonts, vector graphics and images are preserved exactly. Only the composition of the documents changes.
What ranges are valid when splitting?
Use formats like 1-5, 8-12, 20-30. Ranges must stay within the document, the first page must be less than or equal to the last, and ranges must not overlap. Clear messages explain any mistake.
How do I get several PDFs at once?
When a split produces more than one file, they are bundled into a single ZIP archive you can download in one click. A split that yields exactly one file downloads as a plain PDF.
