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
- Open Images to PDF.
- Drop your JPG or PNG files — one image becomes one page, in the order you add them.
- 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
- Open PDF to images.
- Drop the PDF — every page is rendered at 2× scale for crisp output.
- 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.
