How to merge PDF files
Add your files
Drag your PDF files into the box above, or click to select them. You can also add JPG and PNG images — they become full pages in the merged PDF.
Put them in order
Use the up and down arrows to arrange the files in the exact order you want them combined.
Merge in your browser
Click Merge. Everything is combined locally using your device — nothing is uploaded to any server.
Download one PDF
Save the single merged PDF to your device. There is no watermark and no file-count limit.
Why use this PDF merger
Private & on-device
Your documents are merged locally in your browser and never uploaded — important for contracts, IDs and anything sensitive.
PDFs and images together
Combine multiple PDFs, or mix in JPG and PNG photos and screenshots into one tidy PDF, in any order you choose.
Free & unlimited
No account, no installation, no watermark and no limit on how many files you merge or how often.
What does merging PDF files mean?
Merging (or combining) PDF means joining several separate PDF files into one continuous document, with the pages kept in the order you set. It is one of the most common document tasks — bundling a resume with a cover letter, joining monthly invoices, or combining scanned pages into a single file.
This tool also lets you add JPG and PNG images, turning each picture into a full page, so you can build a PDF from a mix of documents and photos in one step.
Why merge PDFs in your browser?
Most online mergers upload your files to a remote server. For sensitive documents that is a real risk. This tool processes everything on your own device, so your files never leave your computer or phone.
It is also free with no daily task limit, no file-size cap, no watermark and no sign-up — the things free tiers of the big tools usually restrict.
Other ways to merge PDFs
If you prefer not to use a browser tool, here are the built-in options per platform.
Windows
- Open the PDFs in the Microsoft Edge browser one at a time.
- Use Print to PDF and combine, or install a free tool like PDF24 Creator for a dedicated merge option.
macOS
- Open the first PDF in Preview and show thumbnails (View → Thumbnails).
- Drag the other PDFs into the thumbnail sidebar, arrange them, then File → Export as PDF.
iPhone / Android
- Select your PDFs in the Files app.
- Tap Share and choose a merge option, or use this page directly in your mobile browser — it works the same offline-friendly way.
