Is the conversion lossless?

Yes. PNGs are embedded as they are, so text in screenshots stays sharp.

Can I put several screenshots in one PDF?

Yes. Drop them all at once; they are kept in the order you added them.

What about transparent areas?

They show the page's white background in the PDF.

Are my images uploaded?

No. Everything happens in your browser.

PNG to PDF Converter — Free, Lossless, No Upload

PNG to PDF places screenshots, diagrams and other PNG images into a single PDF, one per page. PNG is lossless, and it stays that way: each image is embedded as it is, so sharp text in a screenshot and thin lines in a chart come through without the blur a JPG conversion would add. Add as many images as you need and they are kept in the order you dropped them, which makes it easy to turn a set of screenshots into one document to share.

What you can do

Many images into one PDF, one per page, in the order added.

This tool runs inside your browser tab. Your file is read from your device, processed there, and handed back as a download — it is never sent to a SmilingPDF server, so there is nothing for us to store, read, or lose. You can check for yourself: open your browser's developer tools, switch to the Network tab and run the tool. Like most sites, SmilingPDF uses Google Analytics to count visits and which tools are used; that never includes the contents of your files. The privacy policy lists everything the site does collect.
