About
Built for people who ship images
Comprestack optimizes images without making photographs worse — compress, convert, or both — for freelancers, small teams, and products that need an API.
Why we exist
Optimization should feel like craft, not compromise
Most image tools either oversimplify until quality slips, or bury useful options behind clutter. We wanted something quieter: drop a file, keep the look, leave with a smaller download.
That same idea became an API, white label options, and a dashboard you can hand to clients — still with the short retention and no-training promise.

What we care about
Three promises we keep every day
- 01
Quality first
Optimization should feel invisible. We remove what eyes don’t need and keep the photograph you meant to ship.
- 02
Private by default
Uploads are encrypted in transit and deleted within 1 hour. We don’t sell images or train AI on them.
- 03
Useful on day one
Try as a guest, keep a free account, or plug in the API when volume shows up — no enterprise maze to start.

Where we’re based
Made in Belfast, United Kingdom
Comprestack is run by a small team. Support comes from a real inbox — not a ticket black hole. Reach us anytime at hello@comprestack.com.
