Add your photos, pick a page size, and get one PDF with an image on each page. The order you add them is the order they appear, and you can drop any you change your mind about before converting.
This is mostly used for paperwork — phone photos of receipts that have to go to an accountant as one document, a passport and a visa letter that need submitting together, or a set of ID photos an agency will only accept as a PDF.
JPEG and PNG images are embedded into the PDF exactly as they are. There is no re-compression, so the photos inside the document are the same photos you started with, at the same quality, and the PDF ends up roughly the size of the images added together.
How to jPG to PDF
- Add your images. Up to 100 at once, 100 MB each. JPG, PNG, WebP and HEIC from an iPhone all work.
- Check the order. Images appear in the order they are listed. Remove any you do not want before converting.
- Choose page size and margins. Match the image for a borderless page, or A4 and US Letter for something that has to print on standard paper.
- Convert and download. One PDF, one image per page, named after your first file.
Which page size to choose
Match the image makes each page exactly the proportions of the photo on it. No white bars, no cropping, and pages of different sizes if your images are. This is right for anything that will be read on a screen.
A4 or US Letter forces every page to standard paper. The image is scaled to fit inside and centred, which means white space on any photo whose proportions do not match the page. Use this when the PDF has to be printed, or when whoever is receiving it has specified a paper size.
With a fixed page size, orientation set to Match the content turns each page to suit its image — landscape photos get landscape pages. Forcing portrait or landscape keeps every page the same way up, which looks tidier in a document that will be bound or stapled.
What happens to image quality
A JPEG is embedded into the PDF as the same JPEG data it already was. It is not decoded and re-encoded, so there is no second round of compression and no visible loss — the image in the PDF is bit-for-bit the image in the file. PNG is embedded losslessly in the same way.
WebP and HEIC are the exception. PDF has no native support for either, so those are decoded by the browser and re-encoded as JPEG at high quality before being embedded. That step is lossy. It is usually indistinguishable, but if you are working from HEIC originals and the result matters, convert them to JPEG at full quality first and add those instead.
Because nothing is downscaled, a set of modern phone photos produces a large PDF — twenty 4 MB images give you roughly an 80 MB file. Run it through Compress PDF afterwards if it needs to go by email.
Things that catch people out
Photos of documents are images, not text. The PDF will look like a document but nothing in it is searchable or selectable, because there is no text layer — only a picture of text. Run it through OCR PDF afterwards if you need to search or copy from it.
Rotation metadata is respected. A phone photo carries an orientation tag, and the browser applies it when decoding, so portrait photos come out portrait. Very old images with a broken orientation tag may still land sideways; Rotate PDF fixes those after the fact.
Transparent PNGs get a white background. PDF pages have no alpha channel, so transparency has to become something. White is the only sensible choice; without it, transparent areas would print black.
The file name matters later. The PDF is named after your first image, so if the order is arbitrary the name will be too. Rename the first file before adding if the result is going to someone else.
Questions people actually ask
How do I combine several photos into one PDF?
Add all of them at once — drag them in together or select them all in the file picker. They become one PDF with one image per page, in the order they appear in the list. To change the order, remove an image and add it again so it goes to the end.
Will converting to PDF reduce my photo quality?
Not for JPG or PNG. Those are embedded into the PDF exactly as they are, with no decoding and no second round of compression, so the image in the document is identical to the file you started with. WebP and HEIC are the exception — PDF cannot store them, so they are converted to high-quality JPEG first, which is slightly lossy.
Can I convert iPhone HEIC photos?
Yes. The browser decodes HEIC and the image is embedded as JPEG, because PDF has no HEIC support. Quality is high but the conversion is lossy, so if you have the originals in another format and precision matters, use those instead. Most people will not see a difference.
Why is my PDF so much bigger than I expected?
Because nothing is downscaled. Modern phone photos are 3 to 5 MB each, so twenty of them make a PDF of roughly 80 MB. That is the honest size of the images you supplied. If it needs to go by email, run the result through Compress PDF, which resamples the images down to a size you choose.
Can I search the text in a PDF made from photos?
Not straight away. A photo of a document is a picture — the PDF contains an image, not text, so there is nothing to search or select. Running the finished PDF through OCR PDF adds an invisible text layer over the image, after which it behaves like a normal searchable document.
How many images can I add at once?
One hundred, at up to 100 MB each. The practical limit is your device rather than that number, since the whole job happens in the browser — a phone will struggle with a hundred large photos well before a laptop does. If it fails, convert in two batches and join them with Merge PDF.
