Frequently asked questions

Is the PNG to PNG converter really free?

Yes. Every tool on converteren.com is free, with no sign-up, no watermarks and no hidden limits on the number of files you can convert.

Is my file uploaded to a server?

No. The conversion runs entirely in your browser using modern web technology. Your PNG file never leaves your device — you could even disconnect from the internet after loading the page.

Will the quality be affected?

That depends on the formats involved.

How large can my file be?

You can convert files up to 50.0 MB in this tool. Because processing happens locally, the practical limit also depends on your device's memory — modern laptops and phones handle large files comfortably.

Do I need to install anything?

No. Converteren.com works in any modern browser — Chrome, Firefox, Safari or Edge — on desktop and mobile. There's nothing to download or install.
