Your files are processed by your browser, on this device. They are not uploaded to Hatchio or anyone else, and nothing is kept once you leave the page.
How it works
01Add your PDFs
Drop the files into the box or choose them from your device. Add more at any time.
02Set the order
Drag the files, or use the arrows, until they are in the order you want.
03Combine and download
Press Combine PDFs and download combined-document.pdf.
A real example

Made with this tool on a sample file; the sizes are measured, not estimated.
Good to know
- Pages keep their size, orientation, text and images exactly as they were.
- Up to 30 files and 200 MB at once, and up to 2,000 pages in the result.
- Password-protected PDFs can't be combined until the password is removed.
- Bookmarks and fillable form fields from the original files may not carry over.
Questions and answers
How do I combine PDF files into one?
Add two or more PDFs above, arrange them in the order you want and press Combine PDFs. Your browser joins them and you download one PDF.
Are my files uploaded anywhere?
No. The PDFs are read and combined by your browser on your device. Nothing is sent to Hatchio or to anyone else.
Is there a watermark or a page limit?
There is no watermark. To keep your browser responsive, you can combine up to 30 files and 200 MB at once, with up to 2,000 pages in the result.
