Our Image Compressor helps you reduce image file sizes for faster web loading, easier sharing, and efficient storage. Simply upload your image, choose your desired output format, and adjust the quality slider to find the perfect balance between file size and visual quality.
The tool uses the HTML5 Canvas API to re-encode your image at the desired quality level. For JPEG and WebP formats, lowering the quality significantly reduces file size with minimal visual degradation. PNG compression is lossless, so quality settings have less impact.
All processing happens entirely in your browser using JavaScript. Your images are never sent to any server, ensuring complete privacy and security.
Image compression reduces file size by removing redundant data and applying encoding optimizations. For JPEG and WebP, lowering the quality parameter increases compression by discarding less visible image details. Our tool uses the Canvas API to re-encode your image at the specified quality level.
WebP typically produces the smallest file sizes for photos, followed by JPEG. PNG is best for images with transparency or sharp edges like logos and icons, but produces larger files for photographs. We recommend trying WebP first for the best compression ratio.
It depends on the quality setting and format. At quality levels above 70%, most images show minimal visible degradation. Our tool lets you preview the compressed image side-by-side with the original so you can find the ideal quality setting for your needs.
