DeviceWebP moves the entire file-processing pipeline from the cloud directly to your local browser engine. Key Features: • 100% Serverless: Traditional tools force uploads to external cloud storage networks, creating major data security risks. Your files never leave your device. • High-Stability Queue: Implements a sequential background Web Worker system that safely processes up to 50 large files at once without crashing or freezing your browser tab. • Frictionless: Zero sign-ups or paywalls.

Hi Product Hunt community! 👋
I wanted to share DeviceWebP, a simple, serverless web tool for batch-converting images to WebP right inside the browser.
The goal here was to make a clean, lightweight alternative that runs completely client-side. Because it uses sequential background web workers, your files never leave your device, and the browser tab doesn't freeze up when you drop in a batch of up to 50 images at once. It's completely free, and there are no sign-up gates or paywalls.
I'm really looking forward to hearing your thoughts on how the interface feels, how fast it runs on your hardware, and any features you think would make it more useful. Let me know what you think! 🚀

Really nice that everything runs locally, that was the main draw for me. One thing that would make it even better is adding a simple batch resize option alongside the WebP conversion, since a lot of people converting from PNG or JPEG shots probably want to shrink them for the web too. Right now I have to use a second tool for that step.
An option to resize image dimensions alongside the conversion loop would definitely save time for web optimisation workflows. Appreciate the feedback.

Loaded a batch of 50 RAW files and the queue actually held up without freezing my tab, which genuinely surprised me. The fact that nothing leaves my device is a huge plus for client work.

Love that it stays local, honestly a big win for privacy. One thing that would be nice is a drag and drop folder option so I can convert an entire batch at once instead of selecting files individually. Would save a lot of clicks when dealing with big projects.

@birsenieph Thanks for testing it out.
