How to convert png to webp for faster websites for instagram & tiktok
- Step 1Upload your PNG — Drop your PNG screenshot, icon, UI asset, or photo directly into the converter.
- Step 2WebP encodes locally — The browser Canvas API encodes to WebP without any upload. Adjust quality if needed (80 is the web sweet spot).
- Step 3Download and deploy — Save the .webp file. Update your img src= or CSS background-image to reference the new file and measure the size reduction.
Frequently asked questions
Which browsers support WebP?+
All major modern browsers: Chrome (since 2010), Firefox (since 2019), Safari (since 14 in 2020), and Edge. For older Safari support, use the HTML picture element with a PNG fallback: <picture><source type="image/webp" srcset="image.webp"><img src="image.png"></picture>.
Should I use lossy or lossless WebP for UI screenshots?+
For UI screenshots with text and sharp edges, use lossless WebP (quality 100) to preserve crispness. For photos and illustrations, lossy WebP at 80–85 quality gives the best compression with no visible degradation. The tool defaults to 80 which works well for most web assets.
How much will WebP improve my page speed?+
Switching from PNG to WebP for all images typically improves LCP by 100–400ms on mobile. For image-heavy pages, total page weight reduction of 30–40% is common. Google PageSpeed Insights flags all PNG images as WebP conversion opportunities.
