How do I merge several PDFs into one file?

Choose Merge, select your files, review the page sequence and press Create PDF. Download the completed document using the link that appears.

Can I change page order before merging?

Yes. Each preview has earlier and later buttons. Remove excludes a page, and Undo restores the last edit. Larger documents have paginated previews so every page remains reachable.

How do I split a PDF into separate files?

Choose Split and open one PDF. Enter comma-separated groups using the current page positions: 1-2,3 makes a two-page file and a one-page file. Pages omitted from the groups are excluded; overlapping groups are refused.

Why will it not open my password-protected PDF?

Encrypted PDFs are refused. Unlock a copy in a trusted PDF application first, then choose that copy here.

Is my document uploaded to a server?

No. Reading, previews and export happen locally. The page does not store document bytes in browser storage.

What are the document limits?

The workspace accepts up to 20 files, 50 MB total and 500 pages. Split, rotate and reorder modes use one source document. Choosing new files replaces the current workspace.

Does it preserve forms and digital signatures?

The tool copies page content and page geometry. It does not guarantee preservation of document-level features such as interactive forms, bookmarks or signatures. Keep the original and inspect the exported PDF before relying on those features.

PDF Merger

Choose local PDF files in the order you want to combine them, then inspect their page previews before exporting. Move pages with labelled buttons, rotate individual pages, remove unwanted pages and undo edits. Split mode creates separate PDFs from page groups such as 1-2,3. Documents remain in your browser.

Choose PDF files in merge order

Output name

Pages are copied across with their own size, rotation and content intact, so a merged document keeps each page as it was. It reads the page structure, not the text: an encrypted or malformed file is refused by name rather than partly read.
