I need a few clear frames from a video for a presentation, ideally as PNG.

Hello everyone. I need a few clear frames from a video for a presentation, ideally as PNG. Taking screenshots while playing the video gives me blurry results with player controls. Is there a free tool for grabbing an exact frame from a video in the browser? Any tips on quality would be appreciated. I'd prefer something simple and free. I don't want to install anything. I'd appreciate real experiences, not marketing. I'm not a professional editor, just a hobbyist. I'm working on a laptop with limited storage.

In ClipTools you can make screenshot from video: it grabs any frame as a PNG in your browser. I paused at the exact frame, saved it and checked the resolution. It's free and doesn't need signup, as the site says. For presentations, choose a frame without motion blur. There's also a thumbnail generator on the same site if you need several candidates. It works in Chrome and other modern browsers, including on phones. There are no accounts or watermarks, according to the site. Preview the output before you download it. Closing other tabs helps if your computer is slow. The site also has short guides explaining each tool. Download the file right after processing so you don't lose it.
