About this tool
Screenshots, diagrams, and exported graphics are usually PNG, and the easiest way to send a set of them is one PDF. This converter places each PNG on its own page, losslessly, so text in screenshots stays perfectly sharp. Add as many as you like and they are collected in order.
Pages can match the image size exactly or use A4 or Letter with a margin. Because PNG is embedded without recompression, the PDF is as sharp as the originals; run it through Compress PDF if size matters more than perfect pixels.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your PNG files into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click the button and wait a moment.
- Download the results individually or all at once as a ZIP.
Frequently asked questions
Is the PNG transparency preserved?
Yes. Transparent areas stay transparent in the PDF, which viewers show as white.
Why is my PDF large?
PNG is lossless, so big screenshots make big PDFs. Use Compress PDF with the recommended method to shrink it.
Do password-protected PDFs work?
Not yet. Remove the password in your PDF viewer first, then use the tool.
Is there a page limit?
No. Very large documents simply take longer, since everything is processed on your device.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
