TIFF to WEBP Converter

About WEBP

WebP is an image format developed by Google and released in 2010, designed to replace both JPEG and PNG with a single format that outperforms both. It supports lossy compression (like JPEG), lossless compression (like PNG), and alpha channel transparency (like PNG) — in one format, with smaller files than either. Browser support is now comprehensive: Chrome, Firefox, Safari 14+, and Edge all support WebP natively, which means essentially all users on modern browsers can receive WebP without fallback.

How WebP achieves better compression

In lossy mode, WebP uses the VP8 video codec's intra-frame compression. Unlike JPEG's 8×8 block DCT approach, VP8 analyses larger image regions and applies more accurate prediction of pixel values before encoding the residual. The result is 25–35% smaller files than JPEG at the same perceived quality, with fewer blocking artifacts and better handling of smooth gradients. In lossless mode, WebP uses entropy coding with spatial prediction and is typically 26% smaller than equivalent PNG files. Transparent images are 26% smaller on average than PNG.

When to use WebP

For any web image asset — photographs, product images, blog thumbnails, hero images — WebP is the best general-purpose choice when your audience is on modern browsers. Replacing JPEG with lossy WebP reduces page weight, improves load time, and contributes to better Core Web Vitals scores (particularly Largest Contentful Paint), which are a Google search ranking signal. Replacing PNG with WebP for transparent icons and UI elements reduces bandwidth with no visible quality difference.

WebP limitations

WebP support in desktop image editing and production software remains incomplete. Older versions of Photoshop, Lightroom, print production tools, and many legacy Windows applications do not open WebP natively (modern versions have added support). For images that will be used in editing workflows, print production, or distributed to users who may open them in varied software contexts, JPEG or PNG remains the safer choice. For web delivery specifically, WebP is the right format.
