How to use Images to PDF
- Select your files in the Images field.
- Use Up and Down to set the page order.
- Choose a Page size: A4, US Letter, or Fit the page to each image.
- Set Orientation and a Margin in millimeters.
- Select Create, then download the PDF.
Example: Images to PDF
Put two PNG images into a single PDF.
Options
- Page size
- A4 and US Letter give every page the same shape and scale an oversized image down to fit. Fit the page to each image builds the page around the image instead, so nothing is scaled.
- Orientation
- Match each image turns the page sideways for a wide photo and leaves a tall one upright. The setting is ignored when the page size fits each image.
- Margin (mm)
- The space between the image and the page edge, accepted from 0 to 50 mm. It is measured on every side, and a margin too large for the page size is refused with a message.

A4, US Letter, and what Fit really does
Page sizes in a PDF are measured in points, 72 to the inch. A4 is 595.28 by 841.89 points, which is 210 by 297 mm, and US Letter is 612 by 792 points, which is 8.5 by 11 inches. Pick one and every page keeps that shape, with your image scaled down to sit inside the margin box, so a tall photo and a wide photo get pages of the same size. Fit the page to each image works differently: the page is built from the image size plus the margin, so a 900-pixel-wide image produces a 900-point-wide page and nothing is resampled.
Questions about Images to PDF
Does the tool accept WebP files?
Yes. A WebP file is decoded in your browser and embedded as a PNG, so any transparency is kept. HEIC, TIFF and GIF are still refused, and the message points at the Image Format Converter.
Can I put several images on one page?
Not directly. Each image gets its own page. To build a contact sheet or a collage, arrange the pictures into a single image first, then add that one file.
Will my images be shrunk or cropped?
Nothing is cropped. With A4 or US Letter an oversized image is scaled down until it fits inside the margin, and with Fit the page to each image the page is built at the image's own scale instead.
Does a PNG keep its transparency in the PDF?
Yes. The alpha channel travels with the image, so areas that were see-through stay see-through. A JPEG has no transparency to keep, which is one reason to leave a logo as a PNG.
