# JPG to PDF Converter

> To convert JPG to PDF, add your images to the converter on this page, drag them into order, pick a page size and press Create PDF. It also turns JPEG, PNG and WebP into a PDF, and it joins up to 100 images into one file. The PDF is built in your browser, so nothing is uploaded, and it's free with no sign-up and no watermark. A normal JPG goes into the PDF unchanged, so it loses no quality.

## In depth

### What happens to each image format
A PDF can hold JPEG data as it is, so a normal JPG doesn't need saving again. In our test the JPG's exact bytes were inside the finished PDF. Other files take a different route:
- Normal JPG or JPEG, including progressive and greyscale: copied in unchanged, so nothing is lost.
- JPG with a rotation tag, as many phone photos have: redrawn upright at quality 0.95, because a PDF ignores that tag and the page would come out sideways.
- CMYK JPG: redrawn at quality 0.95 as RGB, so the colours look right in every PDF reader.
- PNG: kept lossless, including any transparency.
- WebP: saved as a JPEG at quality 0.92 on a white background.

### How big the PDF will be, and how long it takes
Expect a PDF about the size of your images added together, because this tool doesn't compress them. We tested large batches on a Windows desktop in Edge, using 4000 × 3000 test images:
- 76 JPGs, 296 MB in total: a 298.5 MB PDF in 2.2 seconds.
- 10 PNGs, 276 MB in total: a 281.6 MB PDF in 19 seconds.

### Why there is a limit
Your browser holds every image and the finished PDF in memory, so the limit depends on your device. We set it at 100 images and 300 MB, which worked in the tests above.
Phones and tablets have less memory than a desktop. If a big batch fails on one, try fewer images at a time.

### A4, US Letter or fit to image?
The three page sizes suit different jobs:
- A4 is 210 × 297 mm, the standard paper size in most countries.
- US Letter is 8.5 × 11 in, the standard in the US, Canada and Mexico.
- Fit to image makes each page the size of its image at 96 pixels per inch, so a 1600 × 1000 image gives a page about 16.7 × 10.4 in. Very large images are scaled down to stay inside the 200 in page limit that PDF readers work to.

### How to check that nothing is uploaded
Many online converters send your files to a server first. This one doesn't, and you can see that for yourself. Open your browser's developer tools, go to the Network tab and create a PDF: no request carries your images.
That makes it a good fit for private files such as ID scans, contracts or receipts. Once the page and its PDF code have loaded, the conversion runs on your device.

## FAQ
Q: How do I convert a JPG to a PDF?
A: Add the JPG to the converter at the top of this page, pick a page size and press Create PDF. Your browser saves the PDF straight away, with no sign-up.

Q: Is this JPG to PDF converter free?
A: Yes. It uses no credits, needs no account and adds no watermark, because the PDF is made on your own device.

Q: Are my images uploaded?
A: No. The converter reads your files in your browser and builds the PDF there, so they never reach our servers. The page loads the PDF code when you press Create PDF, but no image goes with that request.

Q: Can I combine several JPGs into one PDF?
A: Yes. Add up to 100 images and they become one PDF, one image per page, in the order shown. The images can add up to 300 MB.

Q: Does converting JPG to PDF lose quality?
A: Not for a normal JPG, which goes into the PDF unchanged. A JPG that needs turning upright, or one in CMYK colour, is saved again at high quality, so it changes very slightly. PNG stays lossless.

Q: Is JPEG to PDF any different from JPG to PDF?
A: No. JPEG and JPG are the same format with two spellings of the extension, so both work here in the same way.

Q: Can I convert PNG or WebP to PDF?
A: Yes. PNG keeps every pixel, and transparent areas show the white page behind them. WebP is saved as a high-quality JPEG inside the PDF, because a PDF can't hold WebP, so its transparent areas turn white.

Q: What page size should I use?
A: Use A4 outside North America and US Letter inside it if you plan to print. Use Fit to image if the PDF will only be read on a screen and you want each page to match its image.

Q: Will my photo be cropped?
A: No. The whole image always shows. It's scaled to fit inside the margins and centred on the page, so a photo with a different shape from the page leaves white space.

Q: Does it work with HEIC photos?
A: No. It takes JPG, PNG and WebP only. Save a HEIC photo as a JPG first, then add it here.
