Do I need to install software or sign up to resize PNG files?

No. The PNG resizer tool runs entirely in your browser with no download, no plugin, and no account. There is no watermark on the output and no daily usage limit.

Are my PNG files uploaded to a server?

No. Your file is read into browser memory, processed on your own device, and released when you close the tab. Nothing is transmitted, stored, or logged at any stage.

Is there a file size limit?

There is no server-imposed cap because the work happens locally. The practical ceiling is your device memory, so desktops handle large PNG files comfortably while older phones may struggle with very big ones.

Which browsers and devices does this PNG tool support?

Every current version of Chrome, Edge, Firefox, Safari, Brave, and Opera on Windows, macOS, Linux, Android, and iOS. No browser flags or extensions are required.
