Frequently asked questions
Is it safe to merge PDF files here?
Yes, because your files never leave your device. Toolbyte merges PDFs inside your browser, so nothing is uploaded to a server and we cannot see your documents.
Is merging PDFs on Toolbyte free?
Yes, it is completely free. There is no signup, no watermark on the result and no limit on how many times you can merge.
How do I combine PDF files into one?
Add your PDFs, drag them into the order you want, then click merge. The combined file downloads to your device as a single PDF.
Can I change the page order before merging?
You can change the order of the files by dragging them. To reorder or delete individual pages inside a file, use the Organize PDF tool first.
Is there a file size limit?
The limit is your device's memory rather than a server cap. As a guide, a combined size up to about 100 MB works well on most computers and recent phones.
Will merging reduce the quality of my PDF?
No. Pages are copied as they are, so text stays selectable and images keep their original quality. Merging does not recompress your content.
