What is WebP? — The Modern Web Image Format
WebP is a modern image format developed by Google, designed to deliver superior compression for images on the web. It produces files that are 25–35% smaller than JPEG and PNG at equivalent visual quality — making websites faster without sacrificing image fidelity.
What is WebP Format?
WebP (pronounced "weppy") is an image format introduced by Google in 2010. It was created as a replacement for JPEG, PNG, and GIF, combining the strengths of all three into a single format with superior compression. WebP uses both lossy and lossless compression, supports transparency (alpha channel), and can even store animated images — features that previously required different formats for each use case.
The WebP format is based on the VP8 video codec's intra-frame compression algorithm, adapted for still images. This approach allows WebP to achieve compression ratios significantly better than traditional formats, resulting in smaller file sizes that load faster in browsers and apps.
Today, WebP is supported by all major browsers — Chrome, Firefox, Safari (since 14), Edge, and Opera — covering over 96% of global web users. It is widely used by major tech companies including Google, Facebook, and YouTube to serve images faster.
WebP vs JPG vs PNG — Comparison
Advantages and Disadvantages of WebP
✓ Advantages
- 25–35% smaller than JPG at equal quality
- Supports transparency (like PNG)
- Supports animation (like GIF)
- Both lossy and lossless compression
- Supported by all modern browsers
- Improves Google PageSpeed scores
- Better quality at same file size
✗ Disadvantages
- Not supported in very old browsers
- Not all desktop software supports WebP
- Older iOS versions don't support it
- Less suitable for print workflows
- Not as efficient as AVIF for compression
When Should You Use WebP?
Use WebP for: All images on your website — product photos, hero images, thumbnails, blog images. WebP is the best all-around format for web use, balancing compression, quality, and broad compatibility. If you're building a modern website and want to improve Core Web Vitals, converting your images to WebP is one of the most impactful optimizations you can make.
Don't use WebP for: Print production (use TIFF or high-quality JPG/PNG instead), archiving original photos (use lossless formats), or situations where maximum software compatibility is required (use JPG).

Frequently Asked Questions About WebP
Is WebP better than JPG?
For web use, yes — WebP produces files 25–35% smaller than JPG at the same visual quality. However, JPG has 100% browser and software compatibility, while very old browsers don't support WebP. For modern websites, WebP is the better choice.
Does WebP support transparency?
Yes — WebP supports full transparency (alpha channel), just like PNG. This makes it a direct replacement for PNG in web graphics, offering smaller file sizes while preserving transparent backgrounds.
Is WebP supported by all browsers?
WebP is supported by Chrome, Firefox, Safari (version 14+), Edge, and Opera — covering over 96% of global web users. Only very old browsers (IE, old Safari) don't support it.
Can I open WebP files on my computer?
Most modern image viewers support WebP, including Windows Photos, macOS Preview, and most browsers. For older software, convert WebP to JPG or PNG using our free converter.
Is WebP or AVIF better?
AVIF offers better compression than WebP (up to 50% smaller than JPG vs WebP's 35%), but WebP has broader compatibility with older browsers. For most websites today, WebP is the safe choice. AVIF is ideal if you need maximum compression and target modern browsers only.
