Frequently asked questions
WebP usually produces files 25–35% smaller than JPG and much smaller than PNG at comparable quality, which speeds up page loads and improves Core Web Vitals. It is supported by every current browser.
It controls WebP’s lossy compression: lower values shrink the file more but soften detail, higher values keep more detail at a larger size. Around 80–85% is a good balance for photos.
Yes. WebP supports alpha transparency, so a transparent PNG converts to a transparent WebP.
No. The image keeps its original width and height; only the format and compression change. Use the Image Resizer first if you also need to change dimensions.
No. Conversion happens in your browser with the canvas API; the file never leaves your device.
About the Image to WebP Converter
This tool converts JPG, PNG, and GIF images to WebP, the modern image format designed for the web. It runs in your browser, shows a live preview with a before-and-after size comparison, and lets you tune the quality to balance sharpness against file size.
Why WebP matters
WebP was built to make images smaller without an obvious loss of quality, and it delivers: for most photographs it produces files roughly a quarter to a third smaller than an equivalent JPG, and dramatically smaller than a PNG, while looking the same to the eye. Smaller images mean faster page loads, less bandwidth, and better Core Web Vitals scores — which is why search engines and performance tools actively encourage the format. Every current browser supports it, so there is little downside to serving WebP on the web today.
Quality, transparency, and dimensions
The quality slider controls WebP’s lossy compression. Lower settings squeeze the file harder at the cost of fine detail; higher settings preserve more detail at a larger size. For typical photographs, somewhere around 80 to 85 percent gives an excellent balance, and the live size readout lets you find the point where the file is small but still looks right. Transparency is preserved — a PNG with an alpha channel becomes a transparent WebP — and the image keeps its original pixel dimensions, since this tool changes only the format and compression, not the size. If you also need to shrink the dimensions, resize first with the Image Resizer.
Privacy
The conversion uses your browser’s canvas, so the image is processed locally and never uploaded. To reduce a JPG or PNG without changing format, see the Image Compressor; to convert between other formats, see the Universal Image Converter.
