About PNG and JPG

PNG output is lossless and keeps the alpha channel intact.

JPEG has no alpha channel. Transparent areas are filled with the background colour you choose.

PNG files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.

Limitations

  • The conversion runs in your browser, so very large files can exhaust the memory available to the tab.

Frequently asked questions

How do I convert a PNG file to JPG?

Add your PNG file to the box above. convertexa detects the format from the file content, applies the PNG to JPG conversion and gives you the result to download. The whole operation runs inside your browser.

Are my PNG files uploaded anywhere?

No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.

Is the PNG to JPG conversion lossless?

No. JPG is a re-encoded format, so some data is discarded to reach the target format. PNG output is lossless and keeps the alpha channel intact.

Is there a size limit?

For reliable results keep the input under 40 MB. Very large files run out of memory in the browser rather than failing quietly.

Which browsers are supported?

Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
