How to use it
- Choose the pictures or drop them on the box. Each picture's size in pixels appears under its name.
- Put them in order with the up and down arrows, or drag them: the first picture becomes the first page.
- Choose the page size, the orientation, the margin and the picture fit. Keep Match each picture to turn every page to suit its picture.
- Click Make PDF, then Download. The file is called photos.pdf.
Quality and formats
JPG and PNG pictures go into the PDF exactly as they are, so no quality is lost. WebP and GIF pictures are converted to PNG in your browser first. That keeps every pixel, but the file becomes larger. HEIC photos are not read by browsers; convert them to JPG first.
Sideways phone photos
A phone stores the direction it was held in as an EXIF tag and does not turn the picture itself. This tool reads that tag and turns the picture to match in the PDF, so a photo taken sideways comes out upright in every PDF viewer. Pictures without the tag are used as they are.
- Match each picture: every page is as wide or as tall as its picture, after the turn.
- A4 and US Letter pages keep their paper proportions; Fit each picture makes a page the size of the picture plus the margin.
- Small margins are 18 points (a quarter of an inch); large margins are 36 points (half an inch).
Example: three receipts for an expense claim
Add three photos of receipts; two were taken sideways on a phone. Choose A4, Match each picture, a small margin and Show the whole picture.
The result is a 3-page PDF. Each page is a sheet as tall or as wide as its receipt, with the receipt upright and a margin all round.
Frequently asked questions
Are my photos uploaded to a server?
No. Your browser reads the pictures and builds the PDF on your own device. Nothing is sent to our server, which you can check by turning off your internet connection after the page has loaded.
Why do some PDF viewers show a photo sideways?
Some viewers ignore the rotation tag that phones write into a photo. This tool reads the tag and draws the picture upright in the PDF itself, so the result does not depend on the viewer.
Can I use HEIC photos from my phone?
Not directly, because most browsers cannot read HEIC. Save the photos as JPG first, either with your phone's camera settings or with a converter, then add them here.
Does the order of the pictures matter?
Yes. The first picture becomes the first page. Use the arrows to move a picture, or drag it to its new place in the list.
Why is the PDF so large?
Each picture is placed at its full size, so large photos give a large file. A PNG is usually bigger than a JPG of the same picture, so use JPG for photographs.
