What is WEBP Format and Why Should You Use It?
WEBP is a modern image format developed by Google and introduced in 2010. It uses both lossy and lossless compression algorithms that are significantly more efficient than JPEG and PNG. A WEBP image is typically 25–35% smaller than an equivalent-quality JPEG, and up to 80% smaller than a PNG for the same visual output. All major modern browsers — Chrome, Firefox, Safari, Edge — fully support WEBP, making it the recommended format for web delivery in Google's own best-practice guidelines.
Our WEBP compressor lets you reduce the file size of existing WEBP images without converting them to another format. You retain the WEBP efficiency advantages while bringing the file size down to exactly what your project needs.
WEBP vs JPEG vs PNG — Size Comparison
| Format | Typical File Size (1200×800 photo) | Transparency | Browser Support |
|---|---|---|---|
| WEBP (lossy) | ~60–80 KB | Yes | 95%+ modern browsers |
| JPEG | ~100–120 KB | No | 100% |
| PNG | ~300–600 KB | Yes | 100% |
| AVIF | ~40–55 KB | Yes | 90%+ modern browsers |
Sizes are approximate and vary with image complexity and quality setting.
When to Compress a WEBP Image
After Resizing for Web
When you resize a large WEBP from a camera or design tool down to web dimensions, re-compressing it removes the extra quality overhead that was sized for print.
CMS Media Libraries
WordPress, Shopify, and similar platforms accept WEBP. Compressing images before upload keeps your media library lean and your pages fast.
Social Media Sharing
Twitter, LinkedIn, and WhatsApp accept WEBP. A compressed WEBP shares faster and looks as good as the uncompressed original.
Progressive Web Apps
PWA assets stored in the service worker cache must be small. WEBP images at 30–50 KB cache and load near-instantly.
Google Ads & Display
Google Display advertising accepts WEBP creatives. A 40–50 KB compressed WEBP banner meets ad specs and loads faster in ad slots.
Core Web Vitals Optimisation
Serving WEBP instead of JPEG improves Largest Contentful Paint (LCP) — a direct Google ranking signal — because the browser downloads fewer bytes.
Tips for Best WEBP Compression Results
- 1Start with the highest-quality source image available. The compressor can only work with the data that is there — starting from an already heavily compressed WEBP will limit quality.
- 2For photos, lossy WEBP at quality 75–85 is visually lossless to human eyes on screens and yields files 30–40% smaller than equivalent JPEG.
- 3For graphics with flat colours, icons, and logos, lossless WEBP beats PNG by 20–30% in file size with identical visual output.
- 4Use the <picture> HTML element to serve WEBP to supporting browsers with JPEG/PNG fallback for older browsers.
- 5Compress WEBP images to 50–80 KB for above-the-fold content and up to 150 KB for large editorial images.
Frequently Asked Questions — WEBP Compression
Can I compress a WEBP image without converting it to JPEG?
Yes. Our tool recompresses the WEBP and outputs it as a WEBP file. You retain all the format advantages without switching to a less efficient format.
Does WEBP support transparent backgrounds?
Yes. WEBP supports alpha-channel transparency just like PNG, but at a much smaller file size. Our compressor preserves transparency in WEBP outputs.
Is WEBP supported in all browsers?
All modern browsers — Chrome, Firefox, Safari 14+, Edge, and Opera — support WEBP. Browsers older than 2 years may not. For maximum compatibility, serve WEBP via <picture> with a JPEG/PNG fallback.
How much smaller is a WEBP compared to JPEG?
On average, a WEBP image at equivalent perceptual quality is 25–35% smaller than JPEG. For images with flat areas (graphics, UI screenshots), the savings can reach 50%.
Can I batch-compress WEBP images?
Yes — use our Bulk Image Compressor which supports WEBP files and allows you to compress an entire folder of images in one session.
