FAQ

How many files can be merged into one PDF?
The number of files is not limited. In a test, 50 documents with a total size of 350 MB merged in 1 second in Node.js; in the browser it takes a few seconds.
How do I merge photos into a PDF?
There is a separate tool for photos, “JPG to PDF”: it combines JPG, PNG and HEIC into one document, one image per page.
What happens to bookmarks and form fields?
Pages, text, images and vector graphics are transferred unchanged. Bookmarks and interactive form fields are not preserved in this version.
Is it free and without registration?
Yes. No accounts, no limits on the number of files and no watermarks on the result. There is one limit: browser memory; on a regular laptop that means files up to 200-300 MB.
Where does my file go?
Nowhere. The page loads a processing module into the browser, and from then on it runs on your device. The file is not sent to a server; nobody sees it or stores it. You can turn off the internet after opening the page and the tool will keep working.
