Frequently Asked Questions
How much smaller are WebP images compared to JPG and PNG?
WebP images are typically 25% to 35% smaller than comparable JPEGs and up to 80% smaller than PNGs at equivalent visual quality. Converting to WebP significantly boosts site speed and improves Google Core Web Vitals (LCP).
Does converting transparent PNGs to WebP keep the background transparent?
Yes! WebP natively supports 8-bit alpha channel transparency just like PNG, allowing you to compress transparent logos, icons, and cutouts with much smaller file sizes.
What is the difference between Lossy and Lossless WebP modes?
Lossy mode removes redundant image data that the human eye cannot perceive, producing the smallest possible file sizes for photos. Lossless mode compresses image pixels bit-for-bit without discarding any data, perfect for sharp logos, icons, and screenshots.
Can I convert Apple iPhone HEIC photos directly to WebP?
Yes. Our client-side WebAssembly engine decodes Apple HEIC and HEIF photos directly inside your browser memory, converting them into optimized WebP files compatible with all modern browsers.
Are my personal photos uploaded or stored on any server?
No. All conversions, compression loops, and ZIP archiving execute 100% locally inside your device browser memory (RAM). Not a single byte is sent across the internet.
