Frequently Asked Questions
An image compressor reduces the file size of an image by re-encoding its pixel data more efficiently, often with a small, controllable loss in quality. This tool uses your browser's built-in Canvas engine to redraw and re-encode each image locally.
For web use, 70–85% quality usually gives a good balance between visual quality and file size. Use "Maximum Compression" for the smallest possible file size, or raise the slider closer to 100% when quality matters more than size.
JPG, PNG, WEBP, GIF, and BMP are broadly supported across modern browsers. AVIF and TIFF support depends on your specific browser, and HEIC support is limited outside Safari. SVG files are vector graphics, so instead of lossy compression this tool notes that they should be optimized with a dedicated SVG minifier.
