About this tool
About Image Optimizer
Prepare images for faster web delivery by balancing dimensions, format, quality and file size in one place. Image Optimizer is useful for landing pages, product catalogs and content uploads where every kilobyte affects loading time.
This tool is available for browser processing. The main operation runs on your device when supported by the browser and selected format.
When to use this image optimizer
Use it before publishing a hero image, thumbnail, product photo or article graphic. Unlike a simple format conversion, optimization is about the final delivery cost: choose a practical format, remove unnecessary data and keep enough detail for the display size.
How to use this tool
- Add an image and note its original dimensions and file size.
- Choose the output format, quality, dimensions or metadata options available.
- Compare the optimized preview with the source at the size it will appear on the page.
- Download the result only after checking sharpness, transparency and the new file size.
Quality and privacy
Aggressive optimization can create banding, blur or visible compression around text and edges. Keep a high-quality original and use a separate optimized copy for the website. Supported processing runs locally in the browser when available.
