About this Tool

Optimize and compress images directly in browser canvas memory. Adjust quality sliders to reduce KB/MB sizes for fast website loading.

Hardware-Accelerated Raster Processing

HTML5 2D Canvas & WebP/MozJPEG Quantization Pipeline

Images are decoded directly into an in-memory Canvas buffer. Compression algorithms optimize Huffman frequency tables and subsample chroma channels without sending pixels to a server.

Worked Example: Lossless Web Optimization Example

Input:

3.8 MB PNG product photo (3000 x 2000 px)

Output:

340 KB WebP image (91% size reduction) with 100% visual sharpness

Converting from uncompressed PNG raster to modern WebP compression cuts download time by 90% while passing Google Core Web Vitals audits.

Frequently Asked Questions

Why is WebP better than PNG for websites?

WebP supports both lossy and lossless compression, includes 8-bit alpha transparency, and typically produces file sizes 26% smaller than PNGs and 25-34% smaller than comparable JPEGs.

How does image file size impact Google Core Web Vitals?

Large hero images delay Largest Contentful Paint (LCP). Keeping hero images under 150 KB and serving modern WebP or AVIF formats guarantees fast LCP scores under 2.5 seconds.

Does resizing an image alter its aspect ratio?

By default, TTech tools preserve the original width-to-height aspect ratio to prevent stretching or distortion.
