Turn JPG files into PDF
Put your JPG images into a PDF, one per page, at the size and order you choose. PDF is the usual choice for contracts, invoices and anything that must print exactly as designed. Your file never leaves your computer.

How to convert JPG to PDF
- 1 Drop your JPG .jpg or .jpeg or .jpe file onto the page, or click to browse for it.
- 2 Set the page size, orientation and margins, and drag the pages into the order you want.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the PDF, or add more files and do the whole set in one go.
Why convert JPG to PDF
- Paperwork, receipts and scans are expected as one PDF rather than a folder of pictures, and a PDF prints at a predictable size.
- Layout, fonts and colour are fixed, so the file looks the same everywhere.
- Every browser and operating system opens it without extra software.
- Contracts, invoices and anything that must print exactly as designed.
- JPG: detail is thrown away, and each re-save takes a little more.
JPG compared with PDF
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | JPG | |
|---|---|---|
| File extension | .jpg | |
| Compression | Lossy | Lossy or lossless |
| Multiple pages | No | Yes |
| Colour depth | 8 bits per channel, 24-bit colour | RGB, CMYK, greyscale and spot colour with ICC profiles |
| Typical file size | Smaller | Depends on mode |
| Introduced | 1992 | 1993 |
| Developed by | Joint Photographic Experts Group | Adobe, now ISO 32000 |
Quality and what changes
Nothing is lost as long as the image is embedded rather than re-compressed, and a JPG that is already JPEG compressed can often be carried into the PDF byte for byte. The page size you choose decides how large the image appears when printed, not how much detail it holds.
- One PDF limitation to keep in mind: reflowing text for a small screen works poorly and often fails entirely.
Questions about JPG to PDF
Is my JPG file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your JPG is read straight from your own disk, converted on your machine and handed back as a PDF. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several JPG files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate PDF downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
