Want to convert photos to PDF on your phone? An application asks for your documents as a single PDF, but all you have is a handful of photos, and the portal only accepts one file. ResizePing turns JPG and other photos into one PDF on Android and iPhone, with 1, 2 or 4 photos per A4 page, in portrait or landscape.

Need to turn photos into a PDF? ResizePing puts photos on A4 pages, one, two or four per page, on iPhone and Android. Get it on Google Play or the App Store.

  2. Add your photos. You can also share them in from Photos, Files or Drive.
  3. Put them in the order the form needs.
  4. Choose 1, 2 or 4 photos per A4 page, and portrait or landscape.
  5. Create the PDF, check the result screen, then Share or Done.

A single picture instead of a PDF

If you need one image rather than a PDF, ResizePing can combine photos into one picture: vertical, horizontal, or a 2, 3 or 4-column grid. You can reorder them and set the spacing, margin and background colour.

If the PDF is too big

ResizePing can also set photo sizes to an exact file size before you build the PDF. ResizePing also has a PDF compressor on Android and iPhone. Check the result size before you upload. See how to get a PDF under 200 KB.
