If you're here, it's because this happened to you:

Download an image from the web, WhatsApp, Telegram or site... and instead of a JPG/PNG you will find a .webp file. It is not a virus, it is not “broken”: it is only a format designed to be lighter on the web.

Objective of this guide:

What is WebP (and why is it everywhere)

WebP is an image format designed to reduce file weight while maintaining a quality similar to JPG/PNG. In many cases it is smaller to equal visual rendering.

So yes: more and more sites save, serve and download images in WebP because they load faster and consume less bandwidth (especially on mobile).


When you need to convert it to PNG or JPG

FAQ

Is WebP safe?

Yes. It's just an image format.

Why don't some apps open it well?

Because not all legacy software has integrated it in the same way. In that case: convert to PNG/JPG.

WebP spoils quality?

Depends on how it was exported (lossy/lossless). In general it is born to reduce weight while maintaining good quality.

QuantikDash in short

QuantikDash is a quick tool dashboard for conversions and cleaning on files: CSV/Excel, PDF/Docs, images, graphics, text. At the moment there are dozens of presets/tools already ready (conversion, resize, deduplication, extracts, PDF export, favicon, font, etc.). If you miss a specific tool, you can also propose it and evaluate it.
