Phloto is a personal photo management tool that automates tagging, encoding, and web optimization. It processes RAW files into high-bit-depth PNGs and transcodes them into WebP for efficient web use. The tool integrates metadata handling, allowing users to edit captions and alt-text directly within images. Phloto prioritizes user-specific workflows, avoiding generic solutions. It uses 16-bit PNGs for archives and WebP for web efficiency, reducing file sizes without compromising quality.

The tool addresses gaps in existing software, such as metadata loss during RAW development. Darktable and Nitro fail to preserve all Exif data, while Hugo struggles with metadata extraction. Phloto’s approach ensures title and description fields remain consistent across formats. It also filters sensitive metadata, like GPS coordinates, before deploying images online.

Phloto’s design emphasizes non-destructive editing and minimal redundancy. It reads metadata from RAW files, developed PNGs, and existing web files, prioritizing the most recent version. By parsing WebP containers without full decoding, it avoids unnecessary transcoding. The interface leverages htmx for real-time updates, improving responsiveness without heavy client-side code.

While not production-ready, Phloto offers inspiration for developers. Its houseplant nature—built for personal use—highlights the value of tailored tools. By combining metadata control, efficient transcoding, and htmx-driven interactivity, it reimagines photo workflows for modern workflows.
