Offline design software, including the browser apps that work offline
What "offline" has to mean for a design tool, the three kinds of software and how each behaves without a connection, a one-minute test you can run on any of them, and what to do before a flight.

The one-minute test
- Open the tool and open one of your designs while you are online.
- Turn Wi-Fi off (or airplane mode on).
- Reload the page or restart the app. If it does not come back, it needs a connection to load.
- Open a different design, add a text layer, save, and export a PNG. If any of those fails or hangs, it needs a connection for that step.
- Turn Wi-Fi back on. A tool that syncs quietly when it reconnects, without losing what you did, has passed.
The three kinds
| Kind | Examples | Offline | Where files are | Watch for |
|---|---|---|---|---|
| Installed desktop app | GIMP, Inkscape, Krita, Scribus, Affinity, Voidcanvas desktop | Everything | Your disk | Fonts you have not installed; cloud features inside the app |
| Browser app that installs | Voidcanvas (install from the address bar or Add to Dock) | Everything after the first visit, with the exceptions below | The browser's storage on that device, plus .void files you save to disk | Web fonts never used before; AI models not yet downloaded; clearing site data deletes the designs |
| Web app that needs a connection | Most cloud design tools | Little or nothing; some show recent files read-only | Their servers | A dropped connection mid-edit; anything you did not export before the signal went |
The middle kind is the one people do not expect. A browser app can register a service worker that stores the whole app on the device and serves it from there, connection or not. It is still "in the browser", but the browser is now the runtime, not a window onto a server. Whether a given tool does this is what the test tells you.
What needs the internet the first time
Even offline-capable tools fetch a few things once. Prepare them before you go:
- Open the app once and open the parts you use (in Voidcanvas: the Editor, Studio, Effects and any quick tool). They are stored on the device from then on.
- Use every font you plan to use. Web fonts load once and are kept; a font you have never used will not load offline. The 16 fonts built into Voidcanvas are always available.
- Run each AI tool once (Remove background, Select subject, Expand with AI fill). Each downloads its model the first time, then runs on the device.
- Save a .void file of anything important to disk, or install the desktop app so designs are files in a folder you own.
- Export a PNG of the current state of the job, in case you need to send it from a phone.
Offline and private are different
A tool can work offline and still upload your work the moment it reconnects. Offline tells you where the work happens; private tells you where the work goes. Photo editors that do not upload your photos has the network test for the second question. Voidcanvas passes both: the work happens on the device, and by default the only thing sent when you reconnect is an anonymous usage count you can turn off. The optional sharing features (account sync, teams, review links) encrypt on the device before anything leaves.
How Voidcanvas handles this
- In the browser, after the first visit, the home page, Editor, Studio and Effects are stored on the device; the quick tools are stored once visited. Designs live in the browser's storage on that device and can be saved to .void files on disk. Install it from the address bar (Chrome, Edge), Add to Dock (Safari) or Add to Home Screen (iPhone, Android) and it opens in its own window and works with no connection.
- The desktop app for Windows, macOS and Linux is the same app installed, with designs saved as .void files in a Voidcanvas folder inside Documents (or a folder of your choice, including a synced one), the 16 built-in fonts and these Learn pages on the machine, and PSD opening from the file browser.
- Needs the internet once: Google Fonts you have not used, and each AI model the first time. Never needs it: opening, editing, saving, exporting, PSD import, effects, the brand kit.
- Sends when online: anonymous usage counts (off in Your privacy). If you choose to use them, account sync sends your settings, teams send the brands and jobs you share, and review and delivery links send that version's files, all encrypted on the device first. See What Voidcanvas sends.
Can a browser-based design tool work offline?
Yes, if it installs a service worker that stores the app on your device and keeps your files there too. Not every web tool does. Reload it with Wi-Fi off; if it comes back and lets you save and export, it does.
Does Voidcanvas work offline?
Yes, after one visit. The Editor, Studio and Effects are stored on the device, designs are kept in the browser or as .void files, and the desktop app needs no connection at all. Fonts you have never used and AI models you have never run need the internet once.
What free design software works offline on a laptop?
Installed: GIMP and Krita for raster, Inkscape for vector, Scribus for layout, all free. Browser-installed: Voidcanvas, free and with no account. The best choice depends on the job; a layered image editor and a page-layout tool are different things.
Will I lose my designs if I clear my browser?
Designs in browser storage are deleted with the site's data. Keep a .void file of anything that matters, or use the desktop app, where every design is a file in your Documents folder.
