Local processing

Your PDFs are processed in your browser and stay on your device.

Keep text and vectors

Pages are copied without converting them into images. Searchable text and vector artwork remain when present in the original.

Reorder on mobile

Use move buttons on a phone, or drag cards with a mouse. Preview each page before merging.

PDF merge questions

Are my PDFs uploaded?

No. Merging takes place in your browser. No account or public link is created.

Can I reorder or remove individual pages?

Yes. Switch to page mode to move, rotate or remove pages. Restore the original pages if you want to start over.

Which PDF files are supported?

Use unlocked PDFs within the limits shown above. Very complex documents may exceed your browser's available memory.

Are bookmarks, forms and digital signatures preserved?

Preservation of bookmarks and interactive forms is not guaranteed. Digital signatures are invalidated when a document changes. Keep the originals and check the merged PDF.
