About the formats
PNG
PNG is a lossless format with full transparency support, ideal for screenshots, UI graphics, logos, and any image with sharp edges or text. The trade-off is size: photographic content stored as PNG is much larger than JPEG, WebP, or AVIF.
WebP
WebP is Google's web-focused format, supported by every modern browser. It typically lands 25–35% smaller than JPEG at comparable quality and also supports transparency, making it the workhorse choice for fast-loading websites.
Frequently asked questions
Are my PNG files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly codecs — your files never leave your device. After the first visit the converter even works offline.
Can I convert many files at once?
Yes — add as many files (or whole folders) as you like, convert them in one batch, and download everything as a single ZIP. There are no file-count or size limits.
Will I lose quality converting PNG to WebP?
You stay in control: WebP quality is adjustable in the options panel, and the defaults are tuned to be visually indistinguishable for typical images. You can re-convert with different settings instantly.
Does WebP keep my PNG's transparency?
Yes — WebP fully supports alpha transparency, so logos and UI graphics keep their transparent backgrounds at a fraction of the PNG size.
