Compress Buddy

Compress Buddy takes the opposite approach to most online compressors: instead of uploading your images to a server, it runs the compression locally in your browser, so nothing leaves your machine. For anyone compressing client assets, product photography or anything under NDA, that privacy model is the headline feature rather than a footnote. You drop in a batch, compress, and download the results as a zip — no account, no watermark, no per-file queue. Being free with no signup makes it a genuine utility rather than a funnel into a paid tier, which is rare in this category. The trade-offs are inherent to local processing: compression speed depends on your own hardware, very large batches will strain a weak laptop, and you get fewer tuning knobs than a desktop tool like ImageOptim or a build-time pipeline. It is also image-only — no PDFs or video. For quick, private, bulk compression when you do not want files touching a third-party server, it does the job cleanly.
