How to Turn JPG, PNG, and WebP Images into a PDF

Step by step

1. Select supported images

   Choose JPG/JPEG, PNG, or WebP image files. The tool accepts up to 20 images, 25 MB per image, 25 million decoded pixels per image, 40 million combined decoded pixels, and a generated PDF up to 100 MB.

2. Arrange the image order

   Review the image list before creating the PDF. The order shown determines the page sequence; add files in the intended order and use the available move controls to correct it.

3. Choose page settings

   Select A4, US Letter, or Auto / Fit to Image. You can also choose automatic, portrait, or landscape orientation and none, small, or medium margins. Auto orientation can choose a page orientation per image.

4. Create and check the PDF

   Create the PDF and download it when processing finishes. Open the file to review page order, crop/fit, margins, and orientation before printing or submitting it.

A4, US Letter, or Auto

A4 is a common international paper size; US Letter is common in North America. Select the format required by the recipient or printer if the PDF must fit standard paper. Auto / Fit to Image makes a page based on the source image dimensions rather than a standard sheet, which can be useful when consistent printable page dimensions are not required.

For standard page sizes, the image is placed to fit the page area and is not stretched to fill it. Margins reduce the available placement area. Choose orientation automatically when mixed portrait and landscape images should each be fitted according to their shape; choose portrait or landscape when every page should use that orientation.

Understand the output and limits

Each selected image becomes a PDF page. The tool supports JPG/JPEG, PNG, and WebP; other formats such as GIF, SVG, HEIC, or TIFF are not accepted by this workflow. WebP images are decoded in the browser and re-encoded as PNG for embedding, so output size can differ from the source.

The PDF is assembled locally in the browser. Large images can use substantial device memory, so the per-image and combined pixel limits are enforced. If a batch does not fit, use fewer images at a time or reduce image dimensions before conversion.

Keep the reading sequence clear

For scanned pages, check that page 1 is first and page 2 follows it. If file selection adds items in an unexpected order, correct the list before creating the PDF. A reliable filename pattern such as scan-01, scan-02, scan-03 can also help you prepare a batch, but the visible list is the final check.

Common mistakes to avoid

• Choosing a standard paper size when the recipient expects image-sized pages, or vice versa.
• Assuming an image is stretched to fill a page with no whitespace.
• Forgetting that the current order becomes the PDF page order.
• Trying unsupported formats or a batch over the file/pixel limits.

Helpful checks

• Use the recipient's required paper size when submitting forms or printable material.
• Preview the result at actual page size, especially for text in screenshots.
• Keep the source images until the downloaded PDF has been reviewed.
