How does image compression work?

Compression reduces file size by removing redundant data while preserving visual quality.

Will compression reduce image quality?

Our smart compression maintains visual quality while significantly reducing file size (typically 50-80% smaller).

JPEG, PNG, and WebP. Each format uses optimized compression algorithms.

Typically 50-80% size reduction without visible quality loss. Results vary by image type.

WebP is the image format designed specifically for the web. Here's why you should be using it.

WebP is an image format developed by Google in 2010. It provides:

Studies consistently show WebP advantages:

A 100KB JPEG typically becomes 65-75KB as WebP with identical perceived quality.

For lossless images: - 26% smaller than PNG on average - Supports 24-bit color with alpha channel - Faster decoding in browsers

WebP now has over 95% browser support:

The only holdouts are very old browser versions that represent <2% of users.

**Best for:** - Website images - E-commerce product photos - Blog post images - Social media (when supported) - Any image where size matters

**Consider alternatives when:** - Maximum compatibility is critical - Working with print workflows - Using very old systems

**Online tools:** - CompressSpark (this tool!) - Squoosh.app - CloudConvert

**Desktop software:** - Adobe Photoshop (export as) - GIMP - ImageMagick

**Command line:** cwebp input.jpg -q 80 -o output.webp

Like JPEG, WebP uses a 0-100 quality scale:

For maximum compatibility, serve WebP with JPEG/PNG fallbacks:

Using HTML picture element: <picture> <source srcset="image.webp" type="image/webp"> <img src="image.jpg" alt="Description"> </picture>

This serves WebP to supporting browsers and JPEG to others.

AVIF is even more efficient than WebP: - 50% smaller than JPEG - 20% smaller than WebP - Growing browser support

However, WebP remains the practical choice for 2025 due to its balance of compression, quality, and compatibility.
