How to convert images to PDF (and PDF back to images)

Photos of a signed form, a passport scan, a receipt pile — most people are asked for "a PDF" and start with images. The conversion goes both ways and neither direction needs an upload.

Images → one PDF

  1. Open Images to PDF.
  2. Drop your JPG or PNG files — one image becomes one page, in the order you add them.
  3. Review the page thumbnails, then download.

Phone photos are big. If the PDF ends up over an email limit, run the images through Compress image or Resize image first — 2000 px on the long edge is plenty for a readable document page. iPhone HEIC files work too; see HEIC to JPG.

PDF → images

  1. Open PDF to images.
  2. Drop the PDF — every page is rendered at 2× scale for crisp output.
  3. Download the ZIP of PNGs, then unpack it with Extract ZIP if your system doesn't do it automatically.

Choosing the right direction

  • Sending an official document → PDF. It keeps page order and prints predictably.
  • Posting a single page online → image. PNG for text and diagrams, JPG for photos.
  • Need the words, not the picture → run OCR on the exported page, or Extract PDF text if the PDF already has a text layer.

FAQ

Are my photos uploaded?

No. Both conversions run in your browser, so ID scans and paperwork never leave your device.

Can I control page order?

Pages follow the order you add the images. To change it afterwards, drag pages in Re-arrange PDF pages.

Why is my PDF so large?

Because it contains full-resolution photos. Compress or resize the images before converting — a 12 MP photo carries far more detail than a document page needs.

Can I get JPGs instead of PNGs from a PDF?

Export the PNGs, then batch-convert them with Convert image.
