Image Compressor

Reduce image file size by up to 80% without visible quality loss — JPEG and PNG

Large image files slow down websites, increase hosting bandwidth costs, consume mobile data allowances, and degrade Core Web Vitals scores that affect Google search rankings. A 5 MB DSLR photo contains far more data than any screen needs to display it. This image compressor reduces JPG, PNG, and WebP file sizes by 40-80% while preserving visual quality indistinguishable at normal viewing sizes. Compression runs entirely in your browser using the Canvas API — images are never uploaded to any server, making it safe for confidential product photos, personal images, and client work. Batch compress multiple images and download all results in a single ZIP file. Consider a freelance photographer delivering a gallery of 80 wedding shots to a client — raw exports from a mirrorless camera can easily total 400 MB, but after compression the same gallery downloads in seconds on any connection. Or an e-commerce store owner uploading hundreds of product photos who needs each image under 200 KB to meet platform upload limits and keep category pages loading quickly. Bloggers and content creators face the same challenge every time they embed a high-resolution screenshot or illustration into a post — a single unoptimized image can triple a page's load time and push bounce rates higher. Developers, designers, and digital marketers benefit most from this tool, particularly when managing image-heavy projects where manual optimization through desktop software would otherwise consume hours of repetitive work. The batch download as a ZIP makes it straightforward to process an entire product catalog or blog asset folder in one session. Because all processing happens locally in the browser, there is no risk of sensitive images passing through a third-party server — a critical consideration when working with unreleased product photography, medical images, or client brand assets under NDA. No account, no upload limits, and no waiting on server queues.
