I built a 100% Client-Side Image Compressor & WebP Converter (Zero Server Uploads)

Source: Dev.to

Hi DEV Community! 👋

As web developers and bloggers, we compress and convert images daily. But I noticed a huge privacy issue: most free image converters force you to upload your files to their servers.

I didn’t want my private or client images sitting on a random server, so I built a solution: WebPConvert.pro.

Why it’s different

• 🔒 100% Privacy – The entire conversion (WebP ↔ PNG/JPG) and compression happen client‑side in your browser using JavaScript.
• ⚡ Lightning Fast – No server uploads or downloads, so it’s instant.
• 📉 SEO Friendly – Great for compressing images to boost your website’s PageSpeed.

I built the frontend to be super lightweight and fast. I am currently trying to get some initial users and would absolutely love your feedback on the UI and performance!
