How to convert images to PDF, step by step
Converting photos to PDF is quick and takes under a minute:
- Open the Images to PDF tool.
- Choose the JPG or PNG photos, in the order you want them in the PDF.
- Let the browser assemble the PDF, one image per page. The processing runs on your computer, not on a server.
- Download the single PDF, ready to send.
Nothing to install, no account and no upload wait. The result appears instantly, with the same quality as the original photos.
The image order and the supported formats
The images end up in the PDF in the order you load them: the first photo you choose becomes the first page, and so on. If the order comes out wrong, select the images again in the sequence you want and run the tool once more, no need to start over in another tool.
You can mix JPG and PNG in the same run: each image goes on its own page, whatever its source format. And each page comes out at the exact size of the original image, with no cropping and no resizing.
Tips for converting images to PDF
- iPhone photos in HEIC give an "invalid image" error. Many desktop browsers, Chrome and Firefox on Windows especially, cannot decode HEIC. Before loading the photo, convert it to JPG or PNG, for example by sharing it from the iPhone, and try again.
- One image per page, always. Each photo you load becomes its own page of the PDF, at the exact size of the original image, no cropping, no resizing.
- If one photo fails, the whole group stops. The tool processes images in the order chosen and stops as soon as one fails: none of the remaining ones make it into the PDF, even if they are all valid. Remove or convert the problem image before trying again with the whole group.
- Pick the photos in the final order already. Since the first image you choose becomes the first page, select the files in the sequence you want in the PDF.
- The result is not compressed. If the final PDF gets too heavy to email, follow up with the Compress PDF tool, which is free.

Questions about converting images to PDF.
Can I mix JPG and PNG photos in the same PDF?
Yes. The tool accepts JPG and PNG in the same run and places each image on its own page, whatever the source format of each one.
Are the images resized or compressed?
No. Each image goes into the PDF at its original dimensions, and the page takes on exactly the size of that image. If the final file gets heavy, you can reduce it afterwards with the Compress PDF tool, which is free.
Is the image order in the PDF the order I choose them in?
Yes. The first image you choose becomes the first page of the PDF, and so on. If the order comes out wrong, select the images again in the sequence you want and run the tool once more.
An iPhone photo gave me an "invalid image" error. Why?
The photo is probably in HEIC format, which many desktop browsers, Chrome and Firefox on Windows especially, cannot decode. Convert the photo to JPG or PNG, for example by sharing it from the iPhone, and try again.
If one photo fails, do the others still get joined?
No. The tool processes images in the order chosen and stops as soon as one fails: none of the remaining ones make it into the PDF, even if they are all valid. Remove or convert the problem image before trying again with the whole group.
Is there a limit to how many images I can combine?
The tool does not impose a fixed limit. What can limit you is your own computer's memory when processing many high-resolution photos at once.
Are my photos kept on your servers?
No. All the processing happens inside your browser, in JavaScript, and the images are never uploaded anywhere.
