How to convert PNG to PDF
Add PNG files
Drop your screenshots or graphics onto the page. JPG and WebP are accepted too.
Order the pages

Keep each page the same size as its image, or fit images onto A4 or Letter paper.
Download
Create the PDF and save it. Images are placed losslessly.
Key features
Lossless embedding
PNG data is stored in the PDF without conversion to JPG, so text in screenshots stays crisp and readable.
Transparency preserved
Transparent areas in your PNGs remain transparent in the PDF and show the page colour behind them.
Edge-to-edge pages
Margins default to none for PNGs, which suits screenshots and slides exported as images.
Mixed formats
Combine PNG screenshots with JPG photos in a single document if you need to.
Making screenshots into a readable document
Screenshots taken on a phone are tall and narrow. Choose “Same size as each image” so each page matches, or A4 portrait with a small margin if the document will be printed.
PNG files can be large. If the PDF needs to be smaller and the images are photographic rather than text, Compress PDF can convert them to JPG inside the PDF.
Security and privacy
PNG to PDF runs entirely in your browser. Your images are processed in this tab’s memory and never uploaded to PDF365 or anyone else. When you close the tab or press “Start over”, the data is discarded.

Questions about PNG to PDF
Will transparent backgrounds stay transparent?
Yes. The PDF page is white by default, so transparent areas will look white in most viewers, but the transparency is preserved if you place the page on a coloured background in other software.
Can I add PNG images to an existing PDF instead?
Is there a size limit for each image?
Images up to 250 MB are accepted. Very large images (over about 19,000 pixels on a side) are scaled down to fit the PDF page-size limit of 200 inches.
