How to Convert WebP Files Offline
Most "WebP converter" search results are browser-based tools that upload your images to a server. If you're converting sensitive files, working without a reliable connection, or simply don't want your images touching a third party, here's how to convert WebP files entirely offline on Windows.
For Windows 10 & 11 · EV-signed installer · No subscription
Why Convert Offline?
Local conversion means your images are never transmitted anywhere — useful for confidential work, unpublished designs, or client files.
Works Without Wi-Fi
Once installed, webpimage needs no internet connection at all to convert files.
No Account Needed
There's no sign-up, no login, and nothing tied to your identity — just install and convert.

Frequently Asked Questions
Do I need internet access at any point? +
Only to download the installer once. After that, converting files works fully offline.
Where do my converted files go? +
By default, converted images are saved to a Webp2Jpg folder inside your Downloads folder — this location can be changed in the app.
Is this different from an online WebP converter? +
Yes. Online converters upload your image to a remote server to process it. webpimage runs the entire conversion locally on your PC, so your files never leave your device.
