WebP has become the dominant image format on the web, but it remains awkward to work with outside of a browser. Every week, millions of people download a .webp file and then can't open it in Photoshop, attach it to an email, or insert it into a Word document. The solution is simple — convert it to JPG or PNG — but there are dozens of tools claiming to do this, with very different trade-offs.
We have tested the major options and present honest assessments below, organized by use case.

Frequently Asked Questions
What is the best free WebP converter?
For browser images: WebP to JPG/PNG Converter (Chrome extension). For local files on Windows: IrfanView. For Mac: Preview (built-in). For online use with quality control: Squoosh. All are free.
Is Squoosh the best online WebP converter?
Squoosh is the best online converter for individual files because it processes images locally in your browser (no upload), offers granular quality control with live preview, and is built by Google. For batch conversion online, CloudConvert is better.
Can I convert WebP to JPG without installing anything?
Yes. On Windows, use Paint (open WebP, save as JPEG). On Mac, use Preview (export as JPEG). Or use Squoosh online — it processes locally without a server upload. For images found while browsing, the URL trick sometimes works on certain sites.
Which WebP converter has the best output quality?
Squoosh and ImageMagick offer the most quality control. Squoosh shows a live before/after comparison. ImageMagick lets you set any quality value from 1–100. The Chrome extension uses high quality settings by default, producing excellent results without manual configuration.
Is it safe to use online WebP converters?
Squoosh is completely safe as it processes locally. CloudConvert is reputable and deletes files after processing, but it does upload your images. Never use any online converter for private, confidential, or professionally sensitive images. Use a local tool instead.
