JPG → PDF

Combine images into a single PDF. Free, no upload. 1 GB max · Up to 1 GB · Processed locally, never sent to a server.

A letting agent asks for three payslips. An insurer wants photographs of water damage. An accounts team wants the month’s receipts. An online application form asks for both sides of an identity document. What you have is a set of phone photographs, one per file, and a form that accepts a single document. Turning those images into one PDF is what brings most visitors to this page.

The tool takes JPG, PNG and WebP files, as many as you like. Each image becomes a page, in the order shown in the list, and jsPDF assembles the whole thing. Only two settings are offered: the page format, between A4 portrait, A4 landscape and a page shaped to fit each image, and the width of the margins, between none, normal and wide.

Those two settings are enough to change the look of the result completely, and the order of the pages is the one thing the tool cannot guess for you. What follows explains how to pick them according to what you intend to do with the file: upload it to a portal, print it, or simply send it by email.

How to use it

  1. Add the images in the order you want Drop the files or select them; they are appended to the list. The order of the list becomes the order of the pages, and you can drop several batches one after another.
  2. Fix the list if you need to Each row carries two arrows to move it up or down, and a cross to remove that image without starting the whole thing over.
  3. Choose the page format A4 portrait, A4 landscape, or a page fitted to each image, which builds a page with the exact proportions of the photograph instead of placing it inside an A4.
  4. Set the margins None, normal at 24 points or about 8 mm, or wide at 48 points or about 17 mm. The setting applies to every page of the document, with no exception.
  5. Create the PDF and collect it The name of the file being handled is shown during assembly. The result line gives the number of images added, and the document is called images-nexavo.pdf when there is more than one.

Page order, the one thing to watch

Files are taken in the order the system hands them to the browser, which is neither necessarily alphabetical nor necessarily chronological. A rental file whose supporting documents arrive shuffled makes a poor impression, and a claim whose photographs tell no story is hard to follow. Walk through the list before assembling: the two arrows move a row one place at a time, the cross deletes it, and a fresh drop is always appended at the end. No automatic sorting by name or by date is applied.

Choosing between A4 and a page fitted to the image

A4 portrait is the safe reflex for anything that will be printed or uploaded to a portal: every page has the same format, each image being centred and scaled to fit inside the margins. A landscape photograph on a portrait A4 inevitably leaves white bands at the top and the bottom, the price of the uniformity that an administrative department almost always prefers. A4 landscape reverses the reasoning and suits wide screenshots.

The fitted mode removes those bands by giving the page the dimensions of the image, converted at 96 points to the inch. Ideal for a screenshot, much less so for a phone photograph: an image 4,032 pixels wide produces a page about 107 cm across, which is 42 inches. On screen nothing shows; at print time the driver has to scale the whole thing down.

What assembly does to your images

Each image is redrawn on a white background and re-encoded to JPEG at a quality of 0.92 before being placed on the page. Transparency, in a PNG or a WebP, therefore turns to white, and a PNG holding fine text can show faint halos around the letters. The image is also enlarged or reduced to occupy all the space available between the margins: a small image 400 pixels wide will be stretched across the usable width of an A4 and will look soft, since the PDF format does not manufacture detail that was missing from the source file.

Passing through a canvas has one useful side effect: EXIF metadata is not copied across. Capture date, camera model and GPS coordinates stay in your original files. For an identity document or a tax notice, that matters as much as the fact that the images are handled on your own device: the only thing downloaded is jsPDF itself, straight from this site’s assets folder.

Cases where another tool suits better

If you are photographing a text document so that it can later be read back or retyped, the PDF produced here holds images only, with no text layer: go through the optical character recognition tool instead.

If the file is going out by email, every page weighs what its re-encoded photograph weighs, and twenty phone shots quickly exceed what a work mailbox will accept: compress the images first, assemble second. And for archiving photographs without loss, PDF is not the right container; keep your originals.

Frequently asked questions

Can I mix portrait and landscape photographs?

Yes, but the page format you choose applies to every page. In A4 portrait, landscape photographs will leave white bands above and below. The fitted mode does the opposite and follows the orientation of each file.

Will the GPS coordinates of my photographs end up in the PDF?

No. Each image is redrawn in a canvas before insertion, an operation that leaves EXIF data behind. Location, capture date and camera model are not carried into the document.

Why is my PDF heavier than my images put together?

The photographs are re-encoded to JPEG at a fairly generous quality. An image that was already heavily compressed can therefore come out slightly heavier than it went in. If the file is for sending, compress the images before assembling them.

What happens to the transparency in my PNG files?

It is replaced by white. PDF pages are opaque and insertion goes through a JPEG, a format that knows nothing about an alpha channel.

How many images can I assemble in one go?

No ceiling is set, but each image is decoded and then re-encoded before being added: the practical limit is the memory of your device. On a phone, work in batches of around twenty images.

Can I add my images to a PDF I already have?

Not directly, the tool only accepts images. Build the PDF of your images first, then use Merge PDF to join it with the existing document, in whichever order you want.
