How to convert JPG to PDF
- Press Choose files and select your JPG or JPEG photos, or drag them onto the box. On a phone this opens your photo library.
- Put them in order with the Up and Down buttons (or drag on a computer). Remove any you don't want.
- Pick a page size, orientation and margin, or leave the defaults.
- Press Create PDF, then Download. One image gives
photo.pdf; several giveimages.pdf.
Page size: Fit to image, A4 or US Letter
PDF pages are measured in points, where 72 points make one inch. The three choices behave like this:
| Setting | Page size | What happens to the image |
|---|---|---|
| Fit to image | Same as the picture (plus margin) | One page per image, no empty space. A 1600 × 1200 px photo becomes a 1200 × 900 pt page. |
| A4 | 595 × 842 pt (210 × 297 mm) | Scaled down to fit inside the margins and centered. Never enlarged. |
| US Letter | 612 × 792 pt (8.5 × 11 in) | Same as A4, on the US paper size. |
Fit to image treats 1 pixel as 0.75 point (96 DPI, the screen standard), and caps the longest side of a page at 1,440 points (20 inches) so a 12-megapixel photo doesn't become a poster-sized page. The picture itself keeps every pixel. Choose A4 or Letter when the PDF will be printed or attached to a form that expects a standard paper size.
Why your JPG isn't re-compressed
A PDF can carry a JPEG inside it untouched (the format is called DCT in PDF terms). This converter copies your file's bytes straight into the PDF and only adds the page around it. Because nothing is decoded and encoded again, there is no second round of JPEG compression, so no extra blur or blocky edges, and the PDF is about the same size as the photos you added. Tools that redraw each image on a canvas and save it again lose a little quality every time.
Photos that look sideways
Camera sensors record the picture in one fixed direction. When you hold the phone upright, the phone adds an EXIF orientation value (6 means "rotate 90° clockwise to view", 8 means "counter-clockwise", 3 means "upside down") rather than rewriting the pixels. Viewers apply it silently, but a PDF page does not know about it. This tool reads the value from each JPG and rotates the image on the page to match, so portrait phone photos stay portrait, and the file is still not re-encoded.
Using other image types
- PNG is embedded as it is, and any transparent area is shown on white. See the PNG to PDF converter for screenshots and graphics.
- WebP, GIF and BMP are read by your browser and saved in the PDF as PNG, so nothing is lost.
- HEIC (iPhone's default) can't be read by most browsers yet. Use Settings → Camera → Formats → Most Compatible to save new photos as JPG.
Common uses
- Forms and applications. Photo of an ID, receipt or signed page, turned into a single PDF that upload portals accept.
- Scanned paperwork. Take a photo of each page with your phone, put them in order, and send one file.
- Photo albums and portfolios. Fit to image keeps every picture full size, one per page.
- Joining the result with other documents. Use Merge PDF to combine your new PDF with existing ones, or PDF to JPG to go the other way.
Frequently asked questions
How do I convert a JPG to PDF?
Press Choose files (or drop images on the box), pick one or more JPG, JPEG or PNG files, put them in the order you want, then press Create PDF. The PDF is built on your device and a download button appears. Each image becomes one page.
Is it free, and are my photos uploaded?
It is free, with no sign-up, watermark or page limit set by us. Your photos are never uploaded: the PDF is made by code running in your browser, so the files do not leave your phone or computer. You can switch off your internet connection after the page has loaded and the conversion still works.
Can I convert an image to PDF as well as a JPG?
Yes. JPG and JPEG are the focus, but PNG, WebP, GIF and BMP files work too, and you can mix them in one PDF. PNG and JPG are embedded directly. WebP, GIF and BMP are decoded by your browser and saved inside the PDF as lossless PNG. An animated GIF uses its first frame.
Does the PDF lose JPG quality?
No. A JPG is placed in the PDF exactly as it is, without being decoded and compressed a second time, so the picture is as sharp as your original file. The PDF is usually about the same size as the photos you put in.
Why would a photo from my phone come out sideways, and does this tool handle it?
Phones often save a photo with the sensor orientation and add a small rotation flag (EXIF orientation) instead of turning the pixels. Some converters ignore the flag, so the photo ends up sideways. This tool reads the flag and rotates the page content to match, again without re-compressing the picture.
What page sizes can I choose?
Fit to image makes each page the size of its picture. A4 is 595 by 842 points (210 by 297 mm) and US Letter is 612 by 792 points (8.5 by 11 in). On A4 and Letter the image is scaled down to fit and centered, never enlarged beyond its natural size, with an optional small or large margin. Orientation can be automatic, portrait or landscape.
Can I turn iPhone HEIC photos into a PDF?
Not directly yet, because most browsers cannot decode HEIC files. On iPhone, set Settings, Camera, Formats to Most Compatible so new photos are saved as JPG. Photos you already have can be shared or exported as JPG from the Photos app, or you can use a screenshot of them.
Is there a limit on the number or size of images?
We set no limit. The practical limit is your device memory, because every image is held in memory while the PDF is built. A modern phone handles dozens of ordinary photos. If a very large batch fails, split it into two or three PDFs and combine them with the Merge PDF tool.
Does it work on iPhone and Android?
Yes. Choose files opens your photo library or file picker, the page list has Up and Down buttons for reordering without dragging, and the finished PDF downloads or opens in your browser. On iPhone it may appear in the Files app under Downloads.
How do I change the order of the pages?
Use the Up and Down buttons next to each image, or drag an image by its handle on a computer. The PDF follows the list from top to bottom. Remove a file with the cross button, and add more files at any time before creating the PDF.
