WebP vs JPG: which format should you use?

WebP and JPG are not enemies. They solve slightly different problems.

If you care about distribution on the web, WebP is often the better default. If you care about universal compatibility, JPG is still the safer handoff format.

Use WebP when

• the image is staying on the web
• you want smaller file sizes
• the publishing stack already supports it
• you care more about delivery efficiency than broad legacy compatibility

Use JPG when

• the file is being shared across mixed tools and devices
• someone expects a standard image attachment
• the destination app does not handle WebP well
• you want fewer compatibility surprises

The real decision

This is usually not a design philosophy question. It is a workflow question.

Ask:

• where will the file end up?
• who needs to open it?
• does the next tool in the chain support WebP cleanly?

If the answer is uncertain, JPG is still the safer exchange format.

Best practical setup

A good default is:

• keep WebP for web publishing
• convert to JPG only when compatibility becomes the constraint

That avoids unnecessary conversion while still giving you an escape hatch when a workflow breaks.
