Open LAZ Files in Your Browser
LAZ exists because the LAS file was too big to send. Don't download it just to look at it — open it in the browser instead.
Start free and open LAZ files straight in the browser — no download, no decompression step.
No install. Sign up free to try it with a sample dataset.

What is a LAZ file?
LAZ is a compressed version of the LAS format — the same point coordinates, intensity, classification, and return data, packed down to a fraction of the size. It exists for one reason: LAS files get large fast, and a compressed format makes them practical to store and move.
That compression solves the storage problem but not the opening problem — most viewers still expect the file to be decompressed, or converted back to LAS, before you can see anything. A browser-based viewer reads the compressed file directly, so there's no step between "received the file" and "looking at the scan."
How it works
- Sign up free — no card required to start.
- Open your LAZ file in the browser viewer.
- Measure, annotate, and share a link with your team.
More than a viewer
Compare scans over time
Line up two scans of the same site from different dates and see what actually changed. Compare point clouds across time →
Measure in the browser
Distances and dimensions, checked directly in the viewer — no export to desktop software first. Measure point clouds in your browser →
Pin issues to the model
Flag a problem on the exact point in the scan and assign it to someone, instead of describing a location in a message. Annotate point clouds and assign issues →
Overlay against BIM
Put the as-built scan next to the design model and see where they disagree. Verify as-built against BIM →
Frequently asked questions
Is it really free?
Starting is free — sign up and explore the viewer with a sample LAZ dataset. Uploading and working with your own files starts on the Starter plan, from $99 a month.
Is my data private?
Yes. Projects are private by default and access is role-based — only people you invite can open your scans.
Does it decompress LAZ automatically, or do I need to convert first?
It decompresses automatically when you open it. There's no separate conversion step and nothing to install to read the compressed format.
What do I need to view a LAZ file someone shared with you?
Nothing to install and no account to create. Open the link they sent and the scan loads directly in your browser.
Does it work on mobile?
Yes — the viewer runs in a mobile browser, so a scan opens on a phone or tablet in the site cabin as well as at a desk.
