Image to PDF
Put your photos, scans or screenshots into one PDF, or split them across several. Choose the page size, set a maximum file size if a form has a limit, and download. It all happens in your browser.
or drop up to 30 images here

How to turn images into a PDF
- Add your images. Pick them from your phone or computer, or drag them in. Each image becomes one page.
- Choose how many PDFs you want. One PDF with every image, one PDF per image, or a number of your own. With your own number, drag each image into the PDF box it belongs in.
- Put the pages in order. Drag them, or use the arrows under each page. The rotate button fixes any photo that came out sideways.
- Choose a page size and margin. The previews show exactly how each page will look.
- Set a max file size if you need one. Many application portals only accept PDFs up to a certain size, often 1 or 2 MB. Leave it empty if there's no limit.
- Create, then download. You can rename each PDF before or after creating it. With several PDFs, Download all gives you one ZIP file with all of them inside.
Page sizes explained
| Size | Dimensions | Where it's used |
|---|---|---|
| A4 | 210 × 297 mm (8.27 × 11.69 in) | Most countries: Europe, Asia, Africa, Australia |
| US Letter | 8.5 × 11 in (216 × 279 mm) | United States, Canada, parts of Latin America |
| US Legal | 8.5 × 14 in (216 × 356 mm) | Some US legal and real estate paperwork |
| Same as each image | Matches the photo | PDFs that are only read on screen |
With Auto orientation, wide photos get a landscape page and tall ones get a portrait page, so nothing ends up tiny in the middle of the sheet. Pick Portrait or Landscape to force every page the same way.
How the size limit works
A PDF made from photos is mostly the photos themselves, so the way to make it smaller is to make the pictures smaller. The tool does that in two steps:
- Resolution first, at a sensible cap. Pictures are never stored at more than 300 pixels per inch of paper, which is the usual standard for sharp printing. A 12-megapixel phone photo on an A4 page holds more detail than that, so even with no size limit set, each page usually ends up around half the size of the photo it came from.
- Then quality, then resolution again. With a size limit, it lowers the JPEG quality until the PDF fits, but not below 50%, where text in scans starts to look smudged. If that still isn't small enough, it reduces the resolution as little as it can.
If the limit is very tight for the number of pages, say 20 pages under 200 KB, you'll see a warning. In that case, split the document into two PDFs or leave out pages the form doesn't need.
Tips for scanning documents with your phone
- Lay the page flat on a dark, plain surface so the edges stand out.
- Use daylight or a bright room, and keep your own shadow off the paper.
- Hold the phone straight above the page, not at an angle, and fill the frame with the document.
- Check that every line is readable before you build the PDF. Blur doesn't get better later.

Frequently asked questions
Are my images uploaded?
No. The PDF is put together by your browser, on your device. Nothing is sent to our server, which is also why it works quickly even on a slow connection.
How do I get the PDF under 1 MB (or another limit)?
Type the limit into Max file size, or tap a preset, then press Create PDF. The tool lowers the image quality step by step and, only if that isn't enough, the resolution. It checks the size of the finished PDF, and counts 1 MB as 1,000,000 bytes, so it passes upload checks that measure either way.
Which page size should I choose?
A4 is the standard paper size in most of the world. US Letter is used in the US, Canada and parts of Latin America, and US Legal is mostly for American legal papers. If the PDF will only be viewed on screen, Same as each image keeps each page exactly the shape of the photo.
Can I change the order of the pages?
Yes. Each image is one page, in the order shown. Drag a page to a new spot, or use the arrows under it to move it earlier or later. The rotate button turns a sideways photo.
Can I make more than one PDF at once?
Yes. Under PDFs to create, pick One per image to get a separate PDF for every image, or Choose how many and type a number. You then get that many PDF boxes and drag each image into the one it belongs in, in whatever order you like. Images you leave out aren't included. Each PDF gets its own name, and the max file size applies to each one separately.
How do I drag pages on a phone?
Press and hold a page for a moment, then drag it. A quick swipe still scrolls the page as normal. If dragging is awkward on a small screen, every page also has a menu underneath to move it to another PDF, and arrows to move it earlier or later.
Is the text in the PDF searchable?
No. Each page is a picture, the same as a scanner produces. You can read it and print it, but you can't select or search the text unless you run it through an OCR program afterwards.
How many images can I add?
Up to 30 images at a time, split across as many PDFs as you like. Very large sets can take a little while on older phones, because all the work happens on your device.
What about transparent PNGs?
PDF pages here are stored as JPEG images, which can't be transparent, so any transparent areas are filled with white, like paper.
