Explore Boad App Store What is the Image Compressor & Resizer?
Boad Tools Image Compressor & Resizer is a powerful, 100% free online tool that lets you compress and resize JPG, PNG, and WebP images directly in your browser without uploading your files to any remote server.
Why compress images client-side?
Large images are the #1 cause of slow websites, poor Google Core Web Vitals scores, and high bounce rates. Traditional online image compression services upload your private images to cloud servers, which presents privacy risks and can take a long time on slower internet connections.
With Boad Tools, all compression algorithms run locally in your web browser using modern HTML5 Canvas rendering. Your files never leave your computer or phone, guaranteeing 100% privacy and zero wait time.
How to use this tool
- Upload your image: Drag and drop your image file or click to browse. We support JPEG, PNG, WebP, GIF, and BMP.
- Adjust Quality: Use the quality slider (70% - 85% recommended) to achieve the best balance between file size and clarity.
- Resize Dimensions: Change width and height in pixels or choose a preset percentage (25%, 50%, 75%). The aspect ratio lock ensures your image won't stretch or distort.
- Choose Format: Convert to WebP for modern web performance, JPEG for broad compatibility, or PNG for lossless transparency.
