Add up to 30 PNG images (up to 50 MB each), arrange them in order, and download one PDF with a page per image. In the default Original mode the pixels are stored with lossless compression and transparency is kept, so screenshots and graphics stay sharp. You can set the page size, orientation, fit and margins, and the PDF is made in your browser.
Convert PNG images to PDF documents
A PDF is the usual way to share images as a document, hand out slides, or put several images in one file. It keeps the page order and looks the same on every device and printer.
Why convert PNG to PDF?
PNG is a single-image format. A PDF adds pages, a fixed layout and print sizes, which is what forms, clients and printers expect. Typical cases are screenshots for a bug report or archive, worksheets and handouts, design proofs for a client, and images that must print at a specific paper size.
Multiple images in one PDF
Add up to 30 PNG files and they become consecutive pages of one PDF. Drag them in the file list to change the order, then choose the page size (A4, Letter, Legal, A3, A2, A5 or the image's own size), orientation, how the image fits the page, and a margin from 0 to 50 mm. It is much quicker than pasting images into a word processor and exporting.
Quality and file size
PNG images keep their full resolution in the PDF, so high-resolution PNGs print sharply. Transparent areas stay transparent. If you need a smaller file, the Compressed mode re-encodes the images as JPG at a quality you choose, which drops transparency. For PNGs with flat colors, shrinking them first with the PNG compressor is another option.
Private processing
The PDF is created in your browser, and your PNG images are never uploaded to our servers.
Frequently Asked Questions
How do I put multiple PNG images into one PDF?
Add all your PNG files at once. Each one becomes a page in a single PDF. Drag the files to set the page order, adjust the page settings, and download.
Will the image quality be reduced in the PDF?
Not in the default Original mode. The PNG pixels are stored at their original resolution with lossless compression, so they look exactly like your files. Only the optional Compressed mode reduces quality, in exchange for a smaller PDF.
Can I control the page size and orientation?
Yes. Choose A4, Letter, Legal, A3, A2, A5 or the image's own size, and set the orientation to automatic, portrait or landscape. Fit mode keeps each image's aspect ratio.
Is PNG to PDF conversion lossless?
Yes, in Original mode. The image data is stored with lossless compression inside the PDF, together with its transparency, so no detail is lost. The PNG file itself isn't copied in as is, but every pixel is the same.
