Hi Product Hunt! 👋 I’m Matthew, the creator of BiblioFuse. As someone with a massive digital library, I kept running into two frustrating problems: - Image-heavy textbooks and comics were taking up gigabytes of space on my tablet. - Many of my favorite series or fanfictions were split into dozens of tiny, separate EPUB files that cluttered my reader. Existing solutions were either too complex or required uploading my private files to the cloud. I built BiblioFuse to solve this locally on Windows. What does it do? BiblioFuse handles the messy XML structure inside EPUBs so you don't have to. 📉 Smart Compression: Drastically reduce file size by resizing oversized internal images and optionally converting them to efficient WebP format. 🔄 Seamless Merging (Pro Only): Combine multiple EPUB files into one master book. It intelligently regenerates the Table of Contents so navigation still works perfectly. 🔒 Privacy First: Everything happens 100% offline on your machine. The Business Model We believe in sustainable software. The free version allows single-file compression. A simple, one-time purchase (~$5) unlocks the Pro features: unlimited batch compression and the merging tool suite. I'm excited to get this into the hands of fellow book hoarders and digital archivists. Let me know what you think!
