Merge and split PDF files online

One PDF merger and splitter for both jobs: combine several PDFs into a single document, or pull selected pages out of one PDF into a new file. Everything runs inside this browser tab — your documents are never uploaded to a server, so there is no upload queue to wait on and no copy of your file sitting on someone else's disk.

How to merge PDFs

  1. Drop the PDFs you want to combine into the box above, or click to browse. Add as many files as you need.
  2. Drag the files in the list to set the order their pages should appear in.
  3. Click Merge, then download the combined PDF.

How to split a PDF

  1. Drop a single PDF into the box above. Every page is shown as a thumbnail.
  2. Click the pages you want to extract. Selecting them in a different order rearranges them in the output.
  3. Click Split to download the selected pages as a new PDF.

A free PDF splitter and merger that does not upload your files

Most online split-and-merge tools send your document to a server, process it there, and promise to delete it afterwards. This one uses your browser's own PDF engine, so the file never leaves your machine — which makes it usable for contracts, invoices, payroll, medical records, and anything else you would rather not hand to a third party.

It also means there is no account, no watermark, and no daily cap on how many files you can process.

What it does not do

Encrypted PDFs are rejected, so remove any password before merging. Each file is capped at 50 MB. And splitting produces one PDF containing the pages you picked rather than a separate file per page — repeat the split, or delete pages in the editor, if you need individual files.

Merging PDFs one at a time versus generating them in bulk

Merging is a manual, one-document job. If you are repeatedly building the same document for many different people — invoices, certificates, pay stubs, shipping labels — that is mail merge rather than merging, and Mergram automates it: place fields on a PDF template once, connect a spreadsheet, and generate one personalized PDF per row. See PDF mail merge from Excel for how that works.

Frequently asked questions

Is the PDF merger and splitter free?

Yes. Both merging and splitting are free, with no sign-up, no watermark, and no limit on how many files you process.

Are my files uploaded anywhere?

No. Merging and splitting happen locally in your browser. Nothing is transmitted to a server, and closing the tab discards everything.

Can I reorder pages before merging?

Yes. Drag the files in the list to change the order in which their pages appear in the merged document. To reorder individual pages inside a single PDF, use the PDF editor instead.

Does splitting give me one file per page?

Splitting extracts the pages you select into a single new PDF. To end up with one file per page, split once per page — or use the PDF editor to delete the pages you do not want and save each version.

Is there a file size limit?

Each PDF can be up to 50 MB. You can add as many files as you like within that per-file limit. Very large documents may still be slow on an older phone or tablet, since the work happens on your own device.

Can I merge a password-protected PDF?

Not directly. Encrypted PDFs are rejected, so remove the password first and then merge.

Can I combine images and PDFs into one document?

Convert the images to a PDF first with Images to PDF, then merge that file with your other PDFs here.
