How to use the image compressor & resizer.

Add the requested inputs

Use the labelled fields in the workspace above. If example values are provided, try them first or replace them with your own.

Calculate and review

Use the main action when needed. The browser decodes the selected file into a canvas, resizes it proportionally and creates a new local blob.

Try a worked example

Choose a maximum width, WebP or JPEG output and quality, then compare original and output sizes.

Check the assumptions

Metadata and animation may be removed. PNG quality behaves differently from lossy JPEG or WebP compression.
