How to use Image to PDF
- Add one or more JPG, PNG or WEBP images.
- Drag images to reorder them and rotate any that are sideways.
- Choose the page size, orientation, margin and image quality.
- Select Create PDF and download the file.
Why combine images into a PDF
Many applications, offices and teachers ask for a single PDF rather than a set of photos. A PDF keeps pages in a fixed order, prints at a predictable size, and is easier to attach to an email than ten separate images. Common examples are scanned certificates for a job or university application, receipts for an expense claim, handwritten homework, and identity documents photographed with a phone.
Step-by-step
- Add your images. You can select several at once, drag them onto the page, or paste a screenshot.
- Put them in order. Drag a thumbnail to a new position, or use the arrow buttons under each image.
- Rotate any image that is sideways. The thumbnail shows the new orientation.
- Choose the page size, orientation and margin.
- Choose an image quality, then select Create PDF and download the file.

Scanning documents with your phone
Good scans start with good photos. These habits make a real difference to readability and file size:
- Place the page on a dark, flat surface so the edges are easy to see.
- Use daylight from a window and avoid your own shadow falling across the page.
- Hold the phone directly above the page, parallel to it, so the text is not slanted.
- Fill the frame with the page, then crop away the table with the Crop Image tool before converting.
- Turn off the flash, which creates a bright spot in the middle of glossy paper.
Keeping the file small enough to upload
Online forms often limit attachments to 1, 2 or 5 MB. Photos from modern phones are 3 to 5 MB each, so a PDF of several pages can easily exceed the limit. The Smallest file setting reduces each image to a maximum of 1,600 pixels and compresses it more strongly, which usually gives 150 to 300 KB per page while keeping printed text readable. If the file is still too large, convert fewer pages per PDF, or reduce the photos with Compress Image first.
Transparent areas in PNG images are placed on a white page, because PDF pages are white by default.
Privacy
Identity documents, certificates and bank statements are exactly the kind of files people prefer not to upload to an unknown server. This converter creates the PDF in your browser, and the images never leave your device.
Frequently asked questions
How many images can I combine?
Up to 100 images, each up to 25 MB. Very large sets may be limited by the memory available to your browser.
What happens to transparent PNG images?
Transparent areas are placed on a white page, as PDF pages are white by default.
Are my images uploaded?
No. The PDF is created in your browser.
Can I add more images after creating the PDF?
Yes. Select Add images, put them in order and create the PDF again. To add pages to an existing PDF, convert the new images and then combine both files with Merge PDF.
Why is one page landscape and the others portrait?
With Orientation set to Auto, each page follows its image. Choose Portrait or Landscape to make every page the same.
Does it work on iPhone and Android?
Yes. Choose photos from your gallery or files app. On iPhone, set the camera format to Most Compatible so photos are saved as JPG rather than HEIC.
