As I strictly need progressive jpg images, without knowing input format, please add format conversion.
Parameter &of=png, default to input format if not set.
Please note I only need png2jpg.
Thank you and congrats for this wonderful service!

Added output=. Please help testing this feature.
Possible values:
&output=jpg
&output=png
&output=gif
If you specify none, it will keep the origin image format.

What about output to webp?

Comment by Luuk Lamers on 10-8-2016 10:59:00

It would be nice if in the future WebP were added. Maybe with different headers for browsers that don't support it to fallback to jpg
something like
&output=webp-jpg
&output=webp-png

See #68 for follow-up on WEBP output.

It would be good if it could server webp automatically if the request contains the header accept: image/webp

KeyCDN does it well:

Is there any update on respecting webp format if webp is present on accept header?

[kleisauke]

Due to Cloudflare's caching it's technically impossible to change the output depending on the type browser. Please use the <picture>-tag as explained in #214.

Ok, now I get it, as the cached request won't go to origin, unless you use worker. Thanks for the fast reply!
