JPG to PDF Converter
Combine photos or scanned pages into one PDF, in the order you choose. Aspect ratios are preserved, so nothing is stretched. The file is assembled on your device.
Images are centred and scaled to fit inside the margins.
How to use JPG to PDF
- Drop in your images — JPG and PNG are both accepted.
- Drag or use the arrow buttons to put them in the right order.
- Choose a page size, orientation and margin, or let each page match its image.
- Create the PDF and download it.
About this tool
The usual reason to do this is paperwork: a form photographed page by page, receipts for an expense claim, or a set of scans that need to arrive as one document. A PDF keeps the pages in order and in one attachment, which is what most submission systems expect.
Each image is placed on its page scaled to fit inside the margins, keeping its original proportions. Choosing "Match each image" instead makes every page exactly the size of the picture on it, which avoids white bands around photos that are not the same shape as A4 or Letter.
Images are embedded as-is rather than re-encoded, so a JPG keeps the exact bytes it arrived with and the PDF loses no further quality. That also means the PDF is roughly the size of the images you put in: compress the photos first if the result needs to fit an upload limit.
Frequently asked questions
Does this reduce my image quality?
No. JPG data is embedded without re-compression, so the pages in the PDF are pixel-identical to the files you supplied. PNGs are embedded losslessly too.
What page size should I use for scanned documents?
A4 in most of the world, Letter in the US and Canada. Both match what office printers expect, so the document prints without the scaling prompts you get from unusual page sizes.
Why is my PDF so large?
Because modern phone photos are large. A 12-megapixel picture is several megabytes, and ten of them make a PDF in the tens of megabytes. Running the images through the image compressor first, or shrinking them to around 2000 pixels on the long edge, usually cuts the result dramatically with no visible difference on screen.
Can I add a PNG with a transparent background?
Yes, and the transparency is preserved in the PDF. Be aware that transparent areas appear white when printed, and some older PDF viewers render them inconsistently.
