Merge PDF
Merge PDFs without signing up.
Combine multiple PDFs into one file, free and without an account. Check the displayed order, process locally, and download your separate merged copy.
Private by design
Ordinary document processing happens in browser memory. The document is not intentionally uploaded to our application server, so there is no server copy of the file to delete.
No account required
Choose a supported file, complete the task, download the result, and keep control of the original.
How to use it
- 1Open Merge and choose two or more PDFs you are authorized to process. Use the existing Try a safe sample PDF button if you want to explore the workspace first.
- 2Check the displayed file order. Each PDF's pages are appended in that sequence. If it is wrong, clear the selection and choose again before pressing Merge PDFs.
- 3Download merged.pdf immediately when it is ready. Check page count, order and readability before sharing; keep the originals.
Worked example
A two-page PDF plus a three-page PDF
Start with
- First: a two-page non-sensitive sample PDF
- Second: a three-page non-sensitive sample PDF
What to expect
One five-page merged.pdf: the first document's two pages followed by the second document's three pages.
Check your result
- Count five pages and inspect the boundary between pages two and three.
- Test any important links or form fields; merging does not guarantee preservation of every interactive feature.
Illustrative page-order example, not a speed or file-size benchmark. This guide does not select or upload documents.
What it does well
- Combines several PDFs without an account.
- Preserves the selected file order.
- Keeps ordinary document processing on your device.
Important limitations
- Very large combined files may exceed mobile-browser memory.
- Protected PDFs require authorized access first.
- Keep independent originals until the result is verified.
Frequently asked questions
Is the document uploaded?
No. This ordinary tool is designed to process the selected file in browser memory and does not intentionally send document content to our application server.
How many PDFs can I merge?
The result is limited to 300 pages. Free local processing allows 40 MiB combined input; the existing Day Pass raises the combined input limit to 100 MiB, not the page limit. A browser can run out of memory before those limits, especially on a phone.
If something does not look right
Can I merge a JPG or HEIC photo with a PDF?
Convert the supported photos with Images to PDF first, then select that downloaded PDF alongside the other PDFs in Merge. A mixed photo/PDF selection is not accepted by Merge.
Do I need to watch an ad, sign up or buy a pass?
The standard local Merge tool does not require an account or payment. Advertising is currently disabled. The optional Day Pass raises local file limits; no paid pass removes browser-memory or page-count limits.
What if the order or orientation is wrong?
Keep the original files. Reselect them in the desired displayed order, or use Rearrange PDF and Rotate PDF on a downloaded copy. Always review the final page count and order.
Will this preserve a verified digital signature?
Do not rely on a merged output to preserve cryptographic signature validity. Changing or rebuilding a signed document can invalidate its signatures. This service is not intended for regulated or legally sensitive records.
