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
