The fastest, simplest way to convert entire folders of images to WebP, right in your browser.
No uploads, no privacy concerns, no compromises. Just drag, drop, and download.
Tired of slow, ad-ridden websites that force you to convert images one by one? I was too.
I needed a simple tool to convert my project assets to WebP without losing the folder structure. Finding nothing that was fast, private, and folder-friendly, I decided to build it myself.
This is the result: a no-nonsense converter that respects your time and your privacy. The best part? You can drop in an entire folder (like your project's /public directory), and it comes out perfectly converted and structured, ready to use.
- 📂 Preserve Folder Structure: Your original folder and subfolder hierarchy is perfectly preserved in the final ZIP archive.
- 🔒 100% Private & Secure: All processing is done locally in your browser. Your files are never uploaded to any server.
- ⚡ Blazing Fast: Uses modern browser APIs for the fastest possible conversion speeds, even with thousands of images.
- 🗂️ Bulk Conversion: Drag and drop an entire folder and let the app handle the rest. Converts PNGs & JPGs to WebP and copies all other files as-is.
- 🔧 Customizable Output: Adjust the WebP quality with a simple slider or opt for lossless compression.
- ❤️ Open Source: Free to use, and the code is available on GitHub for you to review, fork, or contribute to.
