Merge PDFs

Combine PDFs & images locally - your files never leave your device.

Drop files here or

PDF, PNG, JPG, JPEG, WebP

Combine several PDFs, or a mix of PDFs and images, into one document. Drag the pages into the order you want, rotate or crop any of them, then download the result.

Questions

Do my files get uploaded anywhere?
No. Every tool here runs inside your browser tab, on your own machine. The page also ships a Content-Security-Policy that blocks outbound requests entirely, so uploading is not something the app declines to do. It is something it cannot do. Click the "Private" badge to read the policy actually in force.
Can I merge images and PDFs together?
Yes. PNG, JPEG and WebP images are placed on their own pages and can be mixed freely with PDF pages in any order.
Will the links and form fields still work?
Links keep working and stay in the right place. Form fields are flattened into the page, because copying a page without its document’s form definition would otherwise leave boxes that look editable and are not.
Does it work offline?
Yes. After your first visit the whole app is stored by your browser, so it keeps working with no connection at all. You can install it from the browser menu and use it like any other application.
