How to convert images to PDF and PDF to images
To turn images into a PDF, use Image to PDF: upload JPG, PNG, WEBP or HEIC files, arrange the order and download the document, with one page per image. For the reverse, use PDF to Image and choose PNG, which keeps text sharp, or JPG, which produces smaller files for photographs.
When it is worth combining images into a PDF
Photos of documents, chat screenshots, receipts and scans saved as images are hard to organize and send: each file goes on its own, the order gets lost and many portals only accept PDF. By combining everything into a single PDF, each image becomes a page, in the sequence you define, in a file that opens the same way on any device.
How to convert images to PDF
With the Image to PDF tool:
- Select one or more images: JPG, PNG, WEBP or HEIC.
- Arrange the order in which they should appear, since each image becomes a page.
- Click convert to generate the document.
- Download the PDF and check that the sequence and the orientation of the pages are correct.
Prepare the images before generating the PDF
A little preparation greatly improves the result:
- Crop unnecessary borders and background with Crop Image.
- Fix sideways photos with Rotate Image.
- Shrink very heavy photos with Compress Image; the final PDF weighs as much as the images added together.
- If you have not photographed the documents yet, PDF Scanner uses the camera to generate the PDF directly, with an OCR option.
How to turn PDF pages into images
Posting a page on social media, putting it in a presentation or editing it in an image program requires an image, not a PDF. In PDF to Image, you upload the file, choose the output format and download the images generated from the pages.
PNG or JPG: how to choose
PNG does not lose quality and keeps the edges of letters, tables and charts sharp; it is the best choice for text pages, but it produces larger files. JPG uses lossy compression, which gives much smaller files and works very well for photographs, but can leave letters slightly blurry. When in doubt, use PNG for documents and JPG for pages with photos. To better understand the differences, see the guide to image formats.
Round trip: what changes in the process
Converting a PDF to an image and back to a PDF is possible, but the text stops being text: it becomes pixels, and the file is no longer searchable. If you need to search the content later, apply OCR with PDF to OCR. Always keep the original PDF and use the images only for the specific purpose that prompted the conversion.
Frequently asked questions
Can I combine iPhone photos into a PDF?
Yes. The tool accepts HEIC, the iPhone’s default photo format, as well as JPG, PNG and WEBP, and you set the page order before generating the file.
PNG or JPG: which should I choose when converting PDF pages?
PNG for pages with text, tables and charts, because it keeps edges sharp. JPG for pages with photographs, because it produces much smaller files.
My PDF made from photos came out heavy. What can I do?
Shrink the images before building the PDF with Compress Image, or compress the PDF afterward with Compress PDF. For text documents, 60% to 75% quality is usually enough.
