JPG to PDF

Put JPG or PNG images into one PDF, one image per page. Handy when you've photographed a document and need to send it as a single file somebody can actually open.

Runs entirely in your browser. Your files are never uploaded.

How to use JPG to PDF

  1. 1Pick your images, or drag them onto the box above.
  2. 2Get them into the right order with the arrows.
  3. 3Choose a page size and a margin.
  4. 4Press Convert to PDF and download it.

Why anyone wants a PDF instead of six photos

Landlords, banks, universities and HR departments almost always want one file. Photograph six pages of a tenancy agreement and you've got six images, named by your phone in an order that means nothing to anyone. Convert them and the person at the other end gets one document that opens the same way on every device, with the pages where you put them.

It also stops the thing where the fourth page arrives separately an hour later because the email attachment limit kicked in.

Page size and margins

A4 and US Letter give you a conventional document, with each image scaled to fit and centred on the page. Matching each image means a portrait photo gets a portrait page and a landscape one gets a landscape page, which avoids the wide white bands you get when a photo is forced onto a page the wrong shape.

Fitting each page to its image makes every page exactly as big as the image it holds, plus the margin. Good for screenshots, where standard page sizes just add emptiness. Less good if someone's going to print it, since the pages won't match any paper they own.

Margins are in points, which is the unit PDF uses internally. 72 points is an inch, so the default of 24 is about a third of an inch.

Quality, and the file size that comes with it

JPG and PNG are both formats a PDF can hold directly, so your images go in exactly as they are. No re-encoding, no quality loss.

The consequence is that the PDF ends up roughly the size of the images added together. Eight 4 MB phone photos make a PDF of about 32 MB, and plenty of email systems will bounce that. If you're running into a limit, shrink the images before converting rather than compressing the PDF afterwards. Compressing a PDF full of photographs means re-encoding those photographs, which undoes the lossless embedding you just got for free.

Limits

  • JPG and PNG only. Anything else needs converting to one of those first.
  • 25 MB per image.
  • Images go in untouched, so the PDF is about as big as its images combined.
  • No text recognition. The result holds pictures of text, not text.

Frequently asked questions

Can I use PNG files too?
Yes, and you can mix them with JPGs in the same document. Both go in without re-encoding.
Will the text in my photographed pages be searchable?
No. Each page holds a picture of the text. Making it searchable needs optical character recognition, which this tool doesn't do.
How do I control the page order?
The arrows beside each file set it, and the list is exactly what you'll get. Worth a look before you convert, because browsers hand over dropped files in an order nobody chose.
Why is my PDF so big?
Because the images went in at full quality with no re-encoding, and modern phone photos are several megabytes each. The PDF is roughly their combined size. Shrink the images first if you need a smaller file.
