What a heavy file feels like in Tuvi
Open
Upload the file or open a shared link — the design appears in your browser tab, ready to edit. No download bar, no launcher, no update prompt.
Move around
Zoom from the full page down to a single icon and back. Panning and zooming stay smooth even in files packed with detail — long marketing pages, dense dashboards, illustration-heavy screens.
Edit at full speed
Drag, resize and restyle without waiting on the canvas. The editor keeps up with you, not the other way around — even deep inside a big component library.
Stay smooth together
The speed holds when the whole team joins: teammates' edits appear live without slowing down your view of the file.

Why speed is a feature, not a luxury
A design tool you wait for changes how you design: you zoom out less, explore fewer directions, split files that belong together just to keep things moving. Tuvi is built so the canvas keeps up with you instead — large, detailed files open quickly and stay responsive as you move through them, and the editing feel does not degrade as a project grows from ten screens to a full design system.
Just as importantly, that speed does not demand special hardware. Tuvi runs in the browser on the ordinary laptops your team actually has, and older machines automatically get a simplified drawing mode that keeps files usable. One honest note: very large files — 100 MB and up — take noticeably longer to open; once loaded, they are smooth to work in.
No installs, no IT tickets
Because Tuvi is a browser app, 'setting it up' means opening a link. A new teammate is designing minutes after being invited — no download, no license key, no admin rights. Updates ship silently, so nobody is ever stuck on the old version and nobody loses a morning to an upgrade.
That also means everyone sees the same product: designers on brand-new machines, developers on their own setups, clients and consultants joining from wherever they are. When the tool lives in a browser tab, 'can you open this file?' stops being a question.
Frequently asked questions
Will Tuvi handle my really large files?
Yes — large, detailed files are a designed-for case, with uploads up to 500 MB on Organization (50 MB on Starter, 200 MB on Professional). One honest caveat: files past roughly 100 MB take longer to open, though they stay smooth to work in once loaded.
Do I need a powerful computer?
No. Tuvi runs in the browser on ordinary laptops. Machines without modern graphics support automatically get a simplified drawing mode — text and images render more simply, but your files stay usable.
Is there anything to install or keep updated?
Nothing. Tuvi runs entirely in your browser — open a link and design. Updates arrive on their own, everyone is always on the same version, and IT never needs to get involved.
Does it slow down when the whole team is in the file?
No — collaboration is built in, not bolted on. Teammates' changes appear live without dragging down your canvas, whether two of you are in the file or the whole design team.
