A modern image format offering both lossy and lossless modes plus transparency. WebP was designed to replace both JPG and PNG on the web: lossy mode typically beats JPEG by 25–35% at matching quality, lossless mode beats PNG by around 25%, and both modes support an alpha channel. Every current browser supports it, though some older desktop software still does not.. This page covers what WebP is good at, where it gets in the way, and which free browser tools on TheToolSera read or write .webp files.
Overview
WebP was designed to replace both JPG and PNG on the web: lossy mode typically beats JPEG by 25–35% at matching quality, lossless mode beats PNG by around 25%, and both modes support an alpha channel. Every current browser supports it, though some older desktop software still does not.
Smaller than JPG and PNG at equal quality; Transparency in both modes; Animation support; Supported by all modern browsers. Those properties explain its typical habitat: Web performance and Core Web Vitals, Responsive image pipelines, Transparent graphics that must stay small. If your requirement matches one of those, WebP is almost certainly the right default rather than a compromise.
No format is universal. Patchy support in older desktop apps; Some print workflows reject it; Lossy mode still degrades on re-save. None of these are reasons to avoid WebP outright — they are the specific cases where reaching for a different format saves you time later. On size: WebP is typically 25–35% smaller than an equivalent JPG.
TheToolSera has 4 browser-based tools that handle WebP: Convert Image, Image Compressor, Crop Image, Photo Editor. Each one processes the file locally, so .webp documents are never uploaded — relevant whenever the content is confidential.
