Compress PNG
Frequently asked questions
What does Compress PNG do?
Crush PNGs with smart palette + lossless tweaks. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
Is Compress PNG free to use?
Yes. Compress PNG is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open Compress PNG, do the job, and take the result — nothing is gated behind a signup form.
Does my file get uploaded to a server?
No. Compress PNG runs entirely inside your browser tab, so your file is read and processed on your own device. Nothing is uploaded, which means there is no copy of it on a server to worry about.
Does Compress PNG work on Mac, Windows, and phones?
Yes. Compress PNG runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Will the result have a watermark?
No. ToolMunch never adds a watermark, a badge, or a trailing page to anything you make here. What you get back is what you made.
