JPEG vs WebP vs AVIF (2026 Benchmark): File Size, Quality & Browser Support
Side-by-side compression benchmarks comparing file size, SSIM visual quality, encoding speed, and browser compatibility across identical photographic and UI test images.
How Much Can You Compress an Image Without Losing Quality? (Q100 to Q50 Tested)
We tested quality settings from Q100 down to Q50 across JPG, WebP, and AVIF to find the exact perceptual threshold where file size drops up to 80% with zero visible loss.
How Image Compression Affects Website Speed, Core Web Vitals (LCP) & SEO
Demonstrating how image payload reduction transforms Largest Contentful Paint (LCP), mobile Time-to-Interactive, bounce rates, and Google Search rankings.

Master 9:16 vertical video specifications, H.264 MP4 vs WebM/MOV encoding, GIF-to-MP4 looping, and fast browser video trimming without heavy desktop software.
How We Test Image & Video Codecs
Identical Reference Corpus
Every format comparison uses the exact same uncompressed source bitmaps across four categories: 24MP DSLR photography, transparent e-commerce cutouts, high-contrast UI typography, and looping 60fps clips.
Objective + Visual Metrics
We record output byte weight, percentage reduction, SSIM (Structural Similarity Index), encoding time in milliseconds, and 200% zoom crop inspections.
Zero-Upload Verification
Every benchmark in these guides can be reproduced directly inside your browser using Vexelloom's side-by-side Before/After inspector without uploading files to any server.
