Are my MKV files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and convert something. You will see the page load, plus the analytics and advertising the site is paid for with — and nothing carrying your file.

Is converting MKV to PNG free?

Yes. There is no account, no watermark and no limit on how many files you convert — it runs on your own machine, so it costs us nothing to let you. Files up to 100 MB are handled in the browser.

Does converting MKV to PNG lose quality?

No. PNG stores the same content without discarding anything, so the result is identical in quality to the original. One frame, at full resolution. A still from compressed video carries that compression — a fast-moving moment looks softer than a static one, which is the video’s own encoding rather than anything this conversion does.

Do I need to install anything to open PNG files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the PNG afterwards needs whatever software normally handles Portable Network Graphics on your device.
