Exprort thinline content banner to web format

[GeThib]

Greetings,

I have a web banner 1440x400 px to be produced.

It contains only very thin lines (see attached pictures - both screenshots).

What format or the best way should be to reproduce almost exact line shape and crispy clarity in an exported file for the web? Shall be other web accepted format that png and jpg?

Or some trick to be done - scale, etc?

Attached one screenshot of the original Ai screen and the second with show picture preview option.

Thank you in advance.

Is this a trick question?

You've posted images to this forum. It seems that you know how to save to a web-friendly image format.

The Illustrator manual has an excellent section on exporting for the web. It should explain the raster and vector web formats. If you're posting the image via a CMS, you may have specific image format requirements.
