Web-Optimizing Artwork Files

I need help with reformatting my artwork files for web use. This includes converting them into JPEG and PNG formats, as well as resizing to custom dimensions.

Ideal skills for this project include:

- Proficiency in graphic design software (e.g., Adobe Photoshop, Illustrator)
- Experience in web optimization of artwork
- Knowledge of standard web dimensions

Please note, I require these files to be tailored to specific dimensions, which may not be standard.

The file specs will be provided in batches.

Thanks!
