A full-screen PNG screenshot is commonly 1.5–3 MB. The same picture as a WEBP at quality 80 is usually 150–300 KB, transparency and all — which is why the format exists and why every current browser displays it. PIXLFLW does the conversion in your browser, with the resulting size on the button before you commit to it.
Why convert PNG to WEBP here
- Transparency survives — WEBP carries an alpha channel, so a logo stays cut out.
- A quality slider, and a lossless setting at the top of it — push it to 100 and the WEBP is written losslessly, still smaller than the PNG.
- An exact byte budget — "under 200 KB" is a mode, not a guess: the encoder searches for the quality that fits and reports the real number.
- Nothing is uploaded — screenshots of dashboards and documents are precisely the files that should not go to a stranger's server.
How to convert PNG to WEBP
- Drop the .png file into the upload area above.
- The editor opens with WEBP already picked as the export format.
- Move the quality slider — the size figure follows — and save.
When to stay with PNG
If the file has to be opened by something old. Every browser released since 2020 shows WEBP, but the Windows 10 photo viewer needed an update to do it, and some desktop apps and print shops still reject the extension. For anything going to the web, WEBP is the smaller file for the same picture; for anything going into an unknown pipeline, PNG is the safer one.
