How to combine PDF files
- Add multiple pdf files or images from your device, by drag and drop, or from a link.
- Reorder their position if required.
- Press Combine and download your merged PDF.
Merge PDFs and images in one step
Combine PDF works with documents and photos together, so you can turn a contract, its scanned signature page and a few phone photos into one file to send.
- Supported files format: PDF, JPG, PNG, WebP, HEIC, HEIF, AVIF, TIFF, BMP and GIF.
- Each image becomes one page, sized to fit the image.
- Previews of every file help you to decide the order before you combine them.
Combine in your browser or on our server
Both give you the same merged PDF; you choose where the work happens.
Browser mode
Your files are combined without uploading to server.
Server mode
Your files will be uploaded and processed in server that reduces load in your browser and device memory.
Server mode allowances:
- Without an account: up to 10 files and 100 MB per combine, 5 combines a day.
- With a free account: up to 25 files and 200 MB per combine, 20 combines a day.
- Each file can be up to 100 MB.
- A combine that fails doesn't count toward your limits.

Frequently asked questions
Is there a limit to how many files I can combine?
In browser mode there is no file count or size limit. On our server, a free account combines up to 25 files and 200 MB at a time.
Can I merge images and PDFs into one PDF?
Yes. Add PDFs and images (JPG, PNG, WebP, HEIC etc.) in any mix. Each image becomes one page the size of the image.
Does merging reduce the quality of my PDFs?
No. The text stays selectable and nothing is re-compressed.
Can I combine password-protected PDFs?
Yes. Only if you know the password. The password is used only for that job and never stored, and the combined PDF has no password.
Are my files safe?
In browser mode your files never leave your device. In server mode they are uploaded over an encrypted connection and deleted automatically after 24 hours if you do not delete immediately.
