Image to WebP Converter

WebP is Google's modern image format, introduced in 2010 and now supported by every major browser. Its real strength is flexibility: it can encode in lossy mode like JPEG or fully lossless mode like PNG, it supports an alpha channel for transparency, and it even handles animation in a single file. In typical use WebP files land roughly 25 to 35 percent smaller than the equivalent JPEG or PNG at the same visual quality, which is why it has become the default export target for performance-minded websites.

Converting your images to WebP is one of the most effective things you can do for site speed. Swapping bulky JPEG photos and heavy PNG graphics for WebP shaves real kilobytes off every page, improves Largest Contentful Paint and frees up bandwidth without a visible drop in quality. Because WebP keeps transparency, it can replace PNG for logos and overlays as well as JPEG for photos, letting you standardise on one efficient format across an entire project.

Our bulk WebP converter turns JPG, PNG, HEIC, AVIF, TIFF and more into optimised WebP files in seconds, all in your browser with no account and no watermark. Convert a single asset or a whole folder, then download each file or the full batch as a ZIP. A practical workflow is to keep your original PNG or RAW masters, generate WebP copies for production, and fall back to JPEG only for the rare older client that needs it.
