The first folder was mine
The first audit found 59 PNG files among 169 files named .webp in ImageGuide’s public directory. Reading the historical Git blobs reproduced the count. A file extension had been telling me the wrong thing about my own images.
Press reads file contents to identify formats, then lists dimensions, weight and findings. The first-audit story explains what that changed.
Compare before writing
The interface puts conversion settings beside the files. Choose the format, quality and maximum size, then compare the original and result. It can write WebP, AVIF and JPEG XL.
The ordinary copy workflow writes under optimized/ or another selected destination. The current app also has an explicit replacement mode with an originals backup. Choosing replacement is different from making a copy.
August 2026 repository capture. The comparison lets you inspect the image rather than judging compression from a percentage alone.
Projected savings are estimates. Completed output sizes come from the written files, including files that grew.
Keep the local path local
Audit, comparison and conversion run on the computer. Sirv transfers and hosted Studio tools are explicit remote operations. They are not part of scanning a folder.
The scanner reads headers first. The virtualized list requests thumbnails for visible rows instead of decoding every photograph in a large folder. The CLI provides the same local audit and conversion work, with JSON output for scripts and agents.
Part of ImageGuide
ImageGuide explains delivery choices and audits images already on a web page. Press works on the files before they reach that page. Both need to distinguish a measured result from an estimate.
The public download page links to packaged builds. The screenshots here record the August interface, while the repository continues to change.
What remains imperfect
Camera raw and unsupported HEIC files are counted but excluded from the audit. Savings projections are samples, and local AI availability depends on the platform.
