Put JPG and PNG scans into one PDF
Last updated: 1 October 2026 · Souren Das, FileTools Kit, Bengaluru.
You photographed a form, one page per picture, and the office wants a PDF. JPG to PDF places each image on its own page and downloads one file. The work runs in this tab with pdf-lib. The photos are not uploaded to FileTools Kit.
Order is the whole job
The PDF follows the list order. Put page one first. A sideways photo stays sideways unless you rotate it first. This job does not auto-crop to the paper.
Page size follows the images. A mix of portrait phone photos and a wide screenshot produces mixed page sizes. Crop and rotate before you build the PDF if someone will print it.
Steps
- Open JPG to PDF.
- Add JPG or PNG files the browser can decode. HEIC from some phones will not decode in every browser. Export JPEG from the phone gallery first.
- Reorder. Put the signature page where the reader expects it.
- Download and open the PDF. Check that each photo is a full page.
Size
This step does not recompress aggressively. If a portal caps file size, shrink the photos in the image optimizer first, then build the PDF. In-tab PDF compress does not downsample images the way a server optimizer does.
