How to use it
This JPG to PDF converter turns photos and other images into a single PDF, one image per page, in exactly the order you choose. It is made for sending phone photos of documents, receipts or signed forms as one tidy file. The work happens in your browser: images are not uploaded to a server, and JPGs go into the PDF without being recompressed.
How to convert JPG to PDF
- Click "Choose images" or drop files onto the box. JPG, PNG, WebP, GIF, BMP and AVIF are accepted, and you can keep adding more.
- Put the list in order by dragging, or with the Move up and Move down arrows, and press ✕ to drop anything added by mistake. Pages follow the list from top to bottom.
- Pick a Page size: A4, US Letter or Same as the image.
- Set Orientation and Margin. The defaults, Automatic and Narrow (10 mm), suit most document photos.
- Press "Run tool" or Ctrl + Enter, then save the result from the toolsbasic-images.pdf download button.
Page size, orientation and margins
US Letter (8.5 × 11 in) is the everyday paper in the United States and Canada, so pick it when the PDF is going to an office there. A4 (210 × 297 mm) is the standard almost everywhere else and is selected by default. "Same as the image" leaves paper sizes out of it: the page takes the image's pixel dimensions, counting one pixel as one point, which is 1/72 of an inch. That suits PDFs meant for screens, but phone photos turn into enormous pages this way, since a shot 4000 pixels wide becomes a page about 56 inches (1.4 m) across. Viewers zoom out, and fit to page in the print dialog handles paper.
Automatic orientation gives a landscape page to every image that is wider than it is tall and a portrait page to the rest, so one PDF can mix the two. Choose Portrait when every page has to stand upright; landscape photos then sit smaller in the middle of an upright sheet. A margin of None lets the picture run to the edge, Narrow keeps 10 mm clear and Wide keeps 20 mm. If the file might be printed, use at least Narrow, because most printers cannot print right up to the edge of the paper. With "Same as the image", the margin is added around the picture.
How each image is placed on the page
Every picture is scaled down until it fits inside the margins and is then centered; its proportions never change. Nothing is ever scaled up. On A4 with narrow margins the usable area is about 538 × 785 points, so a 400 × 300 pixel screenshot stays at its natural size of roughly 14 × 10.6 cm, with white space around it. A 4000 × 3000 pixel phone photo, by contrast, is shrunk to fit a landscape A4 sheet. Shrinking here only changes how large the photo is drawn: all of its pixels are still in the file, which works out to about 400 pixels per inch on paper.
Why your JPGs are not recompressed
A PDF can hold JPEG data natively, so the converter copies your JPG bytes straight into the document instead of decoding them and saving a new copy. Skipping that second round of compression means no fresh artifacts, and the finished PDF weighs roughly what the photos weigh together. PNG files are embedded losslessly and keep their transparency. WebP, GIF, BMP and AVIF are not formats a PDF can carry directly, so your browser first redraws them as lossless PNG. An animated GIF contributes only its first frame, and WebP or AVIF files can be read only if your browser is able to display them.
Turning document photos into one application PDF
The most common use is collecting paper documents into one file. Job applications, university and visa portals, school enrollment forms and expense claims often ask for a single PDF, and their rules on size and number of files differ from site to site, so check the upload page each time.
- Shoot flat and from directly above, ideally on a dark surface in daylight; a flash tends to leave glare right over the text.
- Do not rely on the picker's order. Depending on the system, a multi-select can arrive alphabetically or in the order you clicked. The list shows file names and sizes rather than thumbnails, so confirm that front and back pages are in sequence, or add the photos one at a time.
- Look for sideways pages. Some phones save a photo exactly as the sensor captured it, lying on its side, and write an EXIF orientation flag so galleries display it upright. Because the JPG is embedded untouched, such a photo may appear rotated in the PDF. It depends on the phone and the shot, so open the PDF and check; if a page is sideways, straighten that photo with the image rotator and build the PDF again. Judge the direction from how the page looks in the PDF, not from your gallery.
- HEIC is not supported. iPhones save HEIC by default. Switch the camera format setting to Most Compatible to get JPGs, or export existing shots as JPG first. iPhone screenshots are PNG and work as they are.
- Adding pages to a PDF you already have? Make a PDF from the images here, then join the two files with merge PDF.
When the PDF is too big to upload
Since photos go in untouched, the way to a smaller PDF is lighter images before conversion. Lower the quality a little in the image compressor, or bring the long side down to about 2000 pixels with the image resizer; on an A4 page that still means more than 180 pixels per inch, which keeps text easy to read. WebP and AVIF sources deserve a look too: turned into lossless PNG they can grow several times over, so converting them to JPG first, for instance with the WebP to JPG converter, usually gives a far lighter PDF.
Privacy and limits
Your images are read into the browser's memory and the PDF is assembled right there. The photos are not sent to our server and nothing is stored; closing the tab clears them. The only thing the page records is an anonymous usage count after a successful run. The compressor, resizer and rotator suggested above work differently: as image tools they process files on our server, without keeping them. One run takes up to 50 images of up to 100 MB each, though dozens of large photos can be slow on a phone. There is no watermark and no account. The PDF to JPG converter goes the other way, and the full set lives under PDF tools.
