From Photos, Files or Google Drive

Files stay on your device. Nothing is uploaded.

  2. 2Drag the files, or use the arrows, to put them in the right order.
  3. 3Merge and download a single PDF.

Frequently asked questions

How many PDFs can I merge at once?

There’s no file limit. The only constraint is your device’s memory: a typical computer can merge files totaling several hundred MB.

Are my files uploaded to a server?

No. Merging happens entirely in your browser, so your files never leave your device. There’s no sign-up and no watermark.

Can I combine images and PDFs into one file?

Yes. JPG, PNG, WEBP and iPhone HEIC images are added as A4 pages, in the order you arrange them.

Will the merged PDF lose quality or mess up fonts?

No. Each original page is copied as is, so text, fonts and images look exactly like the source files. That includes Thai and any other language.
