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 MiB total (52,428,800 bytes) and 500 pages. Split, rotate and reorder modes use one source document. Choosing new files replaces the current workspace. These are this tool’s processing limits, not universal browser limits.

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.

Can I merge PDFs on Mac, Windows, a Chromebook or iPhone?

Open this page in a current browser, choose Merge and select PDFs from your file picker. Review the thumbnails and use the earlier/later buttons to fix the order, then create and download the PDF. On a phone, select saved files from its file manager. No Adobe application or account is required. This page does not add commands to Preview, Google Drive or another app.

Can I merge scanned pages, JPGs or PNGs with a PDF?

Scans already saved as PDFs can be selected here. For JPG, PNG or other supported pictures, use Image to PDF first, download the PDF and merge it with the other documents here. This workspace accepts PDF files, so an image must be converted first. Merging does not recognize text inside scans; Searchable PDF OCR can add searchable printed-English text afterwards.

Can I merge Word documents or reduce the merged file size?

For Word input, export each document to PDF in your word processor first; this tool does not open DOC or DOCX. For a smaller output, download the merged PDF and use PDF Compressor . Merging copies pages and does not optimize their image size or promise a smaller file.

Does batch merging create one file or several independent batches?

Select multiple PDFs together to combine them into one output, within the 20-file limit. It does not scan folders, group filenames or process several independent merge jobs automatically. Choosing another set replaces the current workspace.

How do I put multiple PDF pages on one sheet?

Merging creates one document while keeping each source page separate. To place several pages side by side on a printed sheet, merge the files here if needed, then open the result in PDF N-up and Booklet Imposition and choose a grid. The number that fits depends on that tool’s grid and paper settings.

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

Files stay on this device. Up to 20 files, 50 MiB total and 500 pages. Choosing files replaces the current workspace.

Choose a PDF to see its pages here.

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.
