How it works
Smart Optimize is now an explicit destination rather than the hidden default on the home page. It keeps the original dimensions and compares safe local encodings only after you start processing.
The result states whether the source format was kept or changed and reports the measured saving behind that decision.
Formats and settings
- There is no unrelated format, resize or target-size control.
- A format changes only when the tested alternative produces a meaningful measured saving.
- Transparent pixels remain in an alpha-capable output.
A concrete example
A JPEG photo may stay JPEG when WebP offers no useful gain, while another photo may become WebP with the measured saving shown in the result.
Know before you start
- Smart Optimize is a practical local comparison, not a perceptual-quality oracle.
- Already efficient files may produce no useful saving.
- Use the dedicated tools when you need an exact format, dimensions or byte target.

Frequently asked questions
Does Smart run on the hub?
No. The hub loads no editor, Worker or codec.
Can Smart silently resize?
No. Its canonical settings lock the original dimensions.
How do I choose a format myself?
Open the dedicated conversion tool from the hub.
