What is WebP Format? Why You Should Use It in 2026

WebP is an image format developed by Google and released in 2010 as a modern replacement for JPEG, PNG, and GIF. It uses advanced compression algorithms derived from the VP8 and VP9 video codecs to achieve significantly smaller file sizes compared to older formats.

The primary advantage of WebP is compression efficiency. For photographic images, a WebP file at 80% quality is visually equivalent to a JPEG at 85-90% quality but 30% smaller in file size. For a website with hundreds of images, this adds up to meaningful bandwidth savings and faster load times.

As of 2026, WebP is supported by all major browsers including Chrome, Firefox, Safari, Edge, and Opera. Safari added WebP support in version 14 (2020), which was the last major holdout. This means WebP now works reliably for over 97% of web users worldwide.

Converting your existing images to WebP is straightforward with ToolPic's Image Converter. Upload any JPEG, PNG, BMP, or AVIF image and select WebP as the output format. The tool preserves transparency from PNG sources and lets you adjust the quality level for lossy conversion.
