Shrink image file size with WebP, JPEG, or PNG output, set a quality target, and resize by max width — all client-side.

Image Optimizer compresses and reformats JPEG, PNG, and WebP files locally using the browser Canvas.

Use it before uploading photos, posting marketing assets, or shipping web images where payload size matters.

01Drop an image or pick one from your device.

02Choose output format and quality, and optionally cap the max width.

03Compare original and optimized sizes, then download the result.

Confirm the input is the format you intended.

Scan the result before using it in a document, URL, config, or message.

Copy only the output you need.

Is my image uploaded to a server?

No. The image is read into the current tab and compressed with Canvas. Nothing leaves your browser.

Which format should I pick?

WebP gives the best compression for photos and UI assets. Use JPEG for compatibility and PNG when you need lossless output.

Does quality affect PNG output?

No. PNG is lossless, so the quality slider is ignored. Reduce dimensions with max width instead.
