Frequently Asked Questions
How much smaller are WebP files compared to JPG and PNG?
Google reports WebP is 25–34% smaller than JPG at equivalent visual quality, and 26% smaller than PNG. A typical 200 KB JPG product photo might become 130–150 KB in WebP with no perceptible quality difference.
Do all browsers support WebP?
Yes as of 2024 — WebP is supported in Chrome, Firefox, Safari (since 2020), Edge, Opera, and all modern mobile browsers. Internet Explorer doesn't support WebP but IE has <1% market share. Safe to use WebP for all new web projects.
What quality setting should I use for WebP?
Quality 80–85 is a sweet spot for most web images: excellent visual quality at significantly smaller file size. For images with text, use 90+. For thumbnails where quality is less critical, 60–70 works well.
Does WebP support transparency like PNG?
Yes. Lossless WebP (quality=100) supports full alpha transparency. Lossy WebP also supports alpha transparency. Convert transparent PNGs to WebP to get both transparency and smaller file size.
Should I use WebP or AVIF for my website images?
WebP is the safe choice today — universal browser support. AVIF offers 50% better compression than WebP but browser support is still incomplete (not supported in Safari as of 2024). Use AVIF with a WebP fallback if you want both.

Does the WebP Konverter work with large image files?
