Professionally compress, resize, and convert JPG, PNG, WebP, and AVIF images securely in your browser.
Supports bulk JPG, PNG, and WebP optimization right here in your browser.
ToolLok’s completely free Image Compressor provides agency-grade photo optimization without the expensive software subscriptions. Utilizing advanced HTML5 Canvas processing, you can drastically reduce the file size of your JPG, PNG, WebP, and AVIF images directly inside your web browser.
Most online image tools upload your personal photographs and corporate assets to remote servers. This tool processes every pixel locally on your device. Zero uploads. Zero data harvesting. Browser-native compression also naturally strips hidden EXIF data, including GPS coordinates.
Need an image to be exactly under 500KB for a government portal or website? Use the Target File Size mode, and the compressor will iteratively calculate the exact quality ratio needed. Easily convert outdated JPEGs into next-gen WebP or AVIF formats for superior Google Lighthouse scores.
Depending on the original format and the complexity of the image, files can often be reduced by 70% to 90% with virtually no noticeable loss in visual quality, especially when converting from JPG to WebP.
