# Image Format Optimizer: AVIF + WebP Converter
A browser-based drag-and-drop tool that converts PNG, JPG, GIF, BMP, TIFF, and WebP
images into AVIF or WebP format with configurable quality. No server. No upload.
Fully client-side.
## The Problem
Security company websites publish demo screenshots, compliance dashboards, and trust page
visuals in legacy PNG/JPG formats. These inflate page weight, slow LCP scores, and signal
poor technical hygiene to the exact buyers you're trying to close.
## The Solution
Drop images in. Select output format. Download optimized files.
- WebP via `libwebp` (Canvas API): 25-34% smaller than JPEG, near-universal support
- AVIF via AV1 codec (WASM encoder): 50% smaller than JPEG, superior quality at low bitrates
- Quality slider: 80-85% recommended for lossy formats (best size-to-fidelity ratio)
- Batch download: convert multiple assets in one pass
- File size delta shown per image (before/after comparison)
## Use Cases
- Optimize screenshots for security product landing pages
- Compress compliance report visuals before embedding in trust portals
- Reduce pentest report image weight before client delivery
- Prep demo assets for YouTube thumbnails and GitHub READMEs
## Impact
- 50-80% reduction in image payload
- 0.5-1.2s improvement in mobile LCP (direct Core Web Vitals impact)
- Zero ongoing cost: runs entirely in the browser
