Image Compressor

A free browser-based image tool that reduce image file size by 50-80% while maintaining visual quality for JPEG, PNG, and WebP. Process your photos and graphics directly in your browser without uploading to any server. Shrinking image file sizes used to mean firing up a dedicated optimization app and fiddling with export presets. This compressor handles that work entirely in the browser, applying smart quantization to strip redundant data while keeping the visual appearance crisp — no installs, no subscriptions. A quality slider lets you choose the trade-off between file size and visual fidelity, with side-by-side before/after comparison so you can see exactly what compression does to your image. Batch mode processes an entire folder of photos at once — ideal for preparing web assets or meeting email attachment size limits. Click the file picker or drop one or more photos onto the workspace, then move the quality slider to dial in the size-versus-clarity trade-off. A live before-and-after panel shows the visual difference, and the current file size updates with every adjustment so you can stop the moment you hit your target. Every byte of compression logic runs inside your browser tab — the original photos and their slimmed-down versions never travel across the network. That matters most when you are optimizing confidential screenshots or client product images that should not leave your machine.
