Convert PNG to PDF
Screenshots and diagrams are usually PNGs. Tick lossless PNG to keep every pixel, or leave it off for a smaller file. Transparent areas become white.

Lossless or smaller?
Lossless keeps text in a screenshot perfectly crisp, but the file can be many times larger. For most sharing, the default is fine and much smaller. If you need a size limit, set one and lossless turns off, because a fixed size needs adjustable quality.

Frequently asked questions
Is my file uploaded?
No. Everything runs inside your browser, on your device. Nothing is sent to a server, so private documents stay private.
How does it stay under my size limit?
All pages share one quality level, so the document looks even. The tool finds the highest quality that fits. If the lowest quality is still too big, it shrinks every page by the same amount and tries again.
Can I change the page order?
Yes. Use the up and down arrows on each page, or drag a row on a computer. The PDF is rebuilt in the new order.
What is the difference between Fit and Fill?
Fit keeps the whole image on the page, with blank space if the shapes differ. Fill covers the whole page and trims whatever falls outside it.
When should I use lossless PNG?
Use it for screenshots and diagrams when you need every pixel kept and have no size limit. Files are larger, and photos are better left as JPG. It is turned off when you set a size limit.
Is it free?
Yes, with no watermark and no sign-up.
