Reduce image file sizes by up to 90% directly in your browser. No uploads, no quality loss, completely private.
Large image files are the primary cause of slow website loading times, which hurts both user experience and SEO rankings. Our Image Optimizer uses advanced client-side compression algorithms to reduce the file size of your JPG, PNG, and WebP images by up to 90% — without any visible loss in quality.
Everything runs entirely in your browser. Unlike other tools that require you to upload your personal photos or proprietary assets to their servers, our Image Optimizer processes your files locally, ensuring 100% privacy and zero wait time for uploads/downloads.
For most use cases, 75–85% quality gives the best balance between file size reduction and visual quality. Most users cannot tell the difference between the original and an 80% compressed image, while the file size is typically reduced by 50–70%.
Currently the tool processes one image at a time for maximum performance and accuracy. For bulk compression, process each image individually.
PNG files with transparency are handled correctly. For maximum compression, the tool may convert to JPEG (which does not support transparency) unless you specifically need PNG output with transparent layers preserved.
Yes — in a positive way. Smaller image files improve page load speed, which is a confirmed Google ranking factor. Google PageSpeed Insights and Core Web Vitals both measure image optimization as part of site performance.
All processing happens locally in your browser. We never see, store, or transmit your data. This tool is fully client-side and secure.
