How to prepare graphic work before posting online in illustration?

Question

Design

Hello everyone,
I have a question about preparing a graphic work before saving it in Illustrator and putting it online. Perhaps someone already has a proven and accurate way.
I have a layout in illustrator, which in the future will be an advertising banner in VK. It consists of illustration, text, elements with gradient, with transparency, with texture effects. I know that in illustrator there are functions "expand fill", "expand stroke" and "expand object", and also there is a function "rasterize appearance". What of all this should be applied before saving, and is it necessary at all, given all that my layout consists of? And then in what format is it preferable to save this work?

Answer 1

1. For yourself, keep the source in ai, do not disassemble anything and do not translate anything into curves. All rasters do not lower the resolution either. It will be a fully editable source where edits are easy to make.
2. In what format does the customer require you to pass it on to him. For the web (you have VK), the main thing is to give in RGB in a raster format.

Answer 2

VK eats only raster format. It will be enough to save the design as a picture and that's it.

Answer 3

1. Break the text into curves
2. Save the file as .eps
3. Attach .jpg and/or .pdf to it for quick viewing.
