Hey Product Hunt community! I built WebP Studio out of personal frustration with the current state of online image converters. Every time I needed to optimize images for web performance or Core Web Vitals, I had to choose between: Cloud converters with 5-file limits, queue timers, and premium paywalls. Uploading sensitive client assets or personal photos to unknown remote servers. WebP Studio solves this by running 100% client-side: - Zero Server Uploads: Your images never leave your device. All encoding is handled locally in your browser using the HTML5 Canvas API. - Bulk Drag & Drop: Drop dozens of images at once and export as a single .zip file. - Split-Screen Comparison Slider: Zoom in and compare the original vs. converted WebP side-by-side to catch compression artifacts in real time. - Format Flexibility: Convert from PNG, JPG/JPEG, HEIC, TIFF, BMP, GIF, and AVIF. - 100% Free & Unlimited: No accounts, no subscriptions, no file size caps. I’d love to get your feedback: How does the conversion speed feel across different batch sizes on your machine? Are there specific compression presets or formats you’d like to see next? Thanks for checking it out!
