MangaSendr

Hey Product Hunt! 👋 I built MangaSendr because I love reading manga on my Kindle, but I hated the process of actually getting the files onto the device. The existing workflows were painful : running python scripts, manually converting PDFs, splitting files to fit the 25MB/50MB email limit, and dealing with bad margins/cropping. I wanted a tool that felt like a high-quality native Mac, so I did it myself (Hi Thanos!) MangaSendr handles all the heavy lifting for you: Smart Splitting: It automatically detects file sizes and splits volumes so they never get rejected by Amazon's email servers. Metadata fetching: It connects to AniList to grab official covers and synopsis, so your library doesn't look like a mess of random filenames. USB Mode: For those with massive libraries (or older Kindles), you can blast transfer 100+ volumes in seconds via USB. Watched Folders: Set a folder, drop a .cbz or .zip file in, and it just appears on your Kindle. Deep optimisation : contrast, smart cropping, spread management, lossless compression. It’s been a passion project to make the reading experience seamless for e-ink readers. I’m shipping v1.0 today and would love to hear your feedback! Happy reading
