Combine one or more PNG images into a PDF
Select one or more PNG images, such as screenshots or diagrams, and arrange them in reading order. Use the page previews to check that text remains legible and that each image is rotated correctly.
Details and limitations
Letter and A4 place each image on a standard paper page with your chosen margins. Match image uses a page size based on that image. Images are fitted without cropping; text inside an image does not become editable text.
What happens to a transparent PNG?
Transparent image areas are retained in the PDF, but most PDF viewers display pages on a white canvas. That white viewing surface does not necessarily mean your original PNG contained a white background.
Details and limitations
If you need a transparent image output instead of a PDF, use PDF to PNG and select Transparent. A white rectangle or white pixels already drawn into a document will still be visible.

Questions before you start?
Can I combine several PNGs into one PDF?
Yes. Arrange the images in the tool before creating the PDF.
What happens to transparent backgrounds?
Check the page preview. Transparent parts may appear against the PDF page background, so review them before downloading.
Will text inside my screenshot become editable?
No. The screenshot is placed on the PDF page as an image. This tool does not perform OCR.
Can I include JPG or HEIC files too?
Yes. The same image-to-PDF tool also accepts JPG and HEIC images.
Try two PNG images in one PDF
Select Try sample files in the workspace above to load two synthetic PNG images. Reorder them, create the PDF, and check that the result has two pages in your chosen order.
