About Bunle
We build tools that make sharing photos instant, lossless, and frictionless.
Why we built this
Sharing 50+ photos shouldn't require a ZIP file, a cloud drive folder, or a 25 MB email limit. Yet in 2026, that's still the default experience for most people.
We created Bunle — an open-source image container format that streams photos like video. Recipients see images appearing in real-time as data arrives. No download, no app, no account.
The format is MIT-licensed. The CLI and JS SDK are free. We charge for the cloud service — hosting, CDN, and convenience features like permanent links and analytics.
How it works
Bunle packs your images into a single .bnl file with a small index at the beginning. The index contains every image's dimensions, format, and byte offset — so the gallery layout renders instantly, before any image data downloads.
Images pass through byte-for-byte. No re-encoding, no compression, no quality loss. WebP, JPEG, and JXL all work.
What we believe
Open source first
The format, CLI, and SDK are MIT-licensed. You can self-host everything. We sell convenience, not lock-in.
Your pixels, untouched
We never re-encode, compress, or downsize your images. What you upload is exactly what recipients see.
No account needed
Anonymous shares work without signing up. Recipients never need an account, an app, or a plugin.
Privacy by default
No tracking cookies, no data selling, no AI training on your images. We use essential cookies only.
Team
Bunle is built by a small independent team. We're self-funded and profitable through subscriptions.
