FAQ
Image resize questions
Will resize keep the image aspect ratio?
Yes. Keep aspect ratio is enabled by default. Turn it off only when you need an exact stretched size.
Should I resize before compressing?
Usually yes. Reducing pixel dimensions often saves more than changing quality alone.
Are resized images uploaded?
No. The resize tool runs locally in your browser.
