How Do You Convert JPG to PDF?
You convert JPG to PDF by adding your photos to QuickCatPDF's JPG to PDF tool, putting them in order and clicking Convert to PDF. The JPG data is copied straight into the PDF, so every photo keeps its original quality, and the whole job runs in your browser. It works like any JPG to PDF online tool, except your photos never leave your device.
The tool works with one photo or hundreds. It also accepts JPEG, JFIF and JPE files, which are the same format under different names.
How to Convert JPG to PDF With QuickCatPDF
Converting JPG photos to a PDF takes four steps, and none of them need an account.
- Click Select images, or drop your JPG files onto the page. On a phone you can also tap Take photo.
- Drag the thumbnails into the order you want. Use Rotate left, Rotate right or Remove on any photo that needs it.
- Pick your settings: Page size, Margins and Images per page. The defaults (fit to image, no margins) keep each photo at its natural shape.
- Click Convert to PDF, then Download PDF.
If you want each photo as its own file, set Output to PDF per image (ZIP) and you'll get one ZIP with a PDF for every JPG.
Why Use QuickCatPDF for JPG to PDF?
QuickCatPDF keeps your photos at full quality because it doesn't re-compress them. Many converters decode a JPG and save it again, which loses a little detail each time; here the original image data goes into the PDF unchanged. In our test, a 253 KB, 12-megapixel photo became a 254 KB PDF.
Privacy is the second reason. The conversion happens on your device, so photos of ID cards, receipts or family events are never sent to a server. Before a photo goes into the PDF, the tool also removes its EXIF data, including the GPS location many phones store in every picture.
The honest limits: the tool doesn't make text inside a photo searchable, and it won't hit an exact file size at Original quality. For an upload limit, use Image to PDF under 200KB.
Which Page Size Should You Pick for JPG Photos?
Fit to image is the best choice for screens, because each PDF page takes the exact shape of its photo with no white borders. Choose a paper size when you plan to print.
| Page size | Best for |
|---|---|
| Fit to image | Sharing photos on screen, keeping the original shape |
| A4 | Printing outside North America, forms and applications |
| US Letter | Printing in the US and Canada |
| Legal, A3, A5 | Long documents, posters and small booklets |
For a JPG to PDF in A4 or Letter size, pick that paper size; Orientation set to Auto turns each page to match the photo, so landscape pictures get landscape pages. Small (10 mm) or Large (20 mm) margins stop printers from cutting off the edges.
How Do You Combine Several JPG Files Into One PDF?
To combine JPG into PDF, add all the files at once and leave Output on One PDF. Each photo becomes one page, in the order shown in the thumbnail grid.
To change the order, drag a thumbnail, use the Move earlier and Move later buttons, or pick Sort by name or by date. The numbers on the thumbnails show the final page order, so check them before you convert.
To save paper, set Images per page to 2 or 4. Two per page suits the front and back of an ID card on one A4 sheet; four per page works well for receipts.
Will the PDF Keep My Photo's Quality and Orientation?
Yes, at the default Original (no quality loss) setting the PDF contains the same JPG data as your file, so nothing is lost. Photos taken sideways on a phone also come out the right way up, because the tool reads the camera's rotation tag and applies it in the PDF.
If the PDF is too large to email, choose High, Balanced or Small file under Image quality. Balanced resizes photos to at most 2,500 pixels on the long side, which cut our 12-megapixel test photo from 253 KB to 63 KB.
Unusual JPGs, such as CMYK files from print software, can't be copied straight into a PDF. The tool converts those automatically without losing quality, so you don't need to do anything different.
Screenshots in PNG convert on PNG to PDF, and pages you photograph with your phone's camera can be cleaned up on Scan to PDF.
Frequently asked questions
Is JPEG to PDF different from JPG to PDF?
No, JPG and JPEG are the same image format, so you convert JPEG to PDF exactly the same way; the shorter name comes from older Windows systems that allowed only three-letter extensions. QuickCatPDF accepts .jpg, .jpeg, .jfif and .jpe files on this page, and it checks the real file type, so a mislabelled file still converts correctly.
Is there a free JPG to PDF converter with no watermark?
Yes, it's free with no sign-up, no watermark and no daily limit. Because your own device does the work, there's no server cost per file to pass on to you. You can convert as many photos as your device's memory allows.
Does it work offline?
Yes, after you've opened the page once, QuickCatPDF works without an internet connection. The site stores its own code in your browser, never your photos. You can also install it like an app from your browser's menu for quick access.
How many JPG files can I convert at once?
There's no fixed limit. Each file can be up to 100 MB, and the tool shows a warning above 150 images or 500 MB in total, because very large batches depend on your device's memory. If a big batch fails, split it into two PDFs.
Can I convert JPG to PDF on my iPhone or Android phone?
Yes, the tool works in Safari, Chrome and other mobile browsers. Tap Select images to choose photos from your gallery, or Take photo to use the camera. iPhone photos in HEIC format work too, or use the HEIC to PDF page.
Are my photos deleted after converting?
Your photos are never uploaded, so there is nothing on a server to delete. They stay in your browser's memory only while the page is open, and clicking Start over or closing the tab clears them.
Can I mix PNG or other images with my JPGs?
Yes, you can add PNG, WebP and other images on this page, and they'll be converted alongside your JPGs. For lots of mixed formats, the Image to PDF page is built for exactly that.
