About this tool
Oversized images are the #1 cause of slow LCP. Drop in JPG or PNG files and compress them — or convert to modern WebP — entirely in your browser with a live quality slider and side-by-side size comparison. Nothing is uploaded, so it works offline and with unlimited files.
How to use the Image Compressor & WebP Converter
- Drop images or click to choose files (JPG, PNG, WebP).
- Adjust the quality slider and pick output format (WebP recommended).
- Download each optimized image or all at once.
Frequently asked questions
How much smaller will my images get?
Typical photos shrink 60–80% at quality 75–80 with no visible difference. WebP is usually 25–35% smaller than JPEG at equal quality.
Is it safe for private images?
Completely — compression runs in your browser via the Canvas API; files never leave your device.
