PNG to PDF Converter

Gather your PNG files in the order you want the pages, then follow these steps.

1. Drag the PNG files onto the box or click to choose them. Add every image that belongs in the document.
2. Reorder with the up and down arrow buttons beside each name. The top file becomes page one.
3. Choose Page size: A4 or US Letter for print, or Same size as each image to keep every screenshot at its own size.
4. Set Orientation and Margin. Wide screenshots usually suit Match each image, and None gives a full-page look.
5. Press Create PDF, then download the file. Transparent areas in a PNG are filled with white.

A single image gives a PDF named after it, and several images give a file called images.pdf, so rename it if you plan to send it. Nothing is uploaded at any step. The page numbers follow the list, so a quick glance at the order before you press the button saves a second run.

PNG is the default format for screenshots, exported slides and interface designs, so a PDF built from PNGs is often a document in its own right:

• Step-by-step guides. Capture each screen of a process, number the files, and combine them into a walkthrough that anyone can open.
• Design approvals. Export each page of a mockup, then send one PDF instead of a folder of images.
• Diagrams and charts. Flowcharts and graphs stay crisp, because PNG pixels are stored without lossy compression.
• Records. Keep a dated screenshot of a confirmation page or receipt together with others in one file.

Remember the content is still a picture. Zooming in shows pixels, not vector lines, and text cannot be selected or searched. If you need to extract words from a screenshot, image to text converter can read them out. The PDF also does not shrink your images, so a stack of full-screen captures from a high-resolution display makes a heavy file. Trim away unneeded borders with the image cropper beforehand.

Take a 1920 by 1080 pixel screenshot of a full screen. These are the three choices that matter, with the numbers they produce.

• Same size as each image, margin None. The page is sized at 0.75 point per pixel, so it measures 1440 by 810 points, which is 20 by 11.25 inches. It suits on-screen reading, and the picture fills the page edge to edge.
• A4, Match each image, margin None. The wide picture gets a landscape A4 page of 841.89 by 595.28 points. It is scaled to the full width, ending up about 474 points tall and leaving roughly 61 points of white above and below. Good for printing.
• A4 with a Large margin. The picture sits inside a 19 mm white frame and is scaled down further, which leaves room for binding or notes.

Pictures of different shapes can share one file. In the A4 setups each page orientation follows its own image, and in the Same size setup each page matches its image. Orientation has no effect in the Same size setup.

Once built, a PDF can be tidied with Rotate PDF if a page came out sideways, or joined to other documents with Merge PDF. The general image to PDF converter takes any image type.

One more habit pays off: keep the screenshots in a numbered naming scheme, such as step-01.png and step-02.png, before you add them. The list shows file names, and clear names make the order easy to check at a glance. Screenshots taken on different devices may differ a lot in size, so open the finished PDF and scroll through it once before sending it to anyone. If a page looks too small, rebuild it with None as the margin, or move to the Same size setup.
