Mobile support, saved projects that really reopen, and drill tables
A big usability release based on a full review of the viewer from a user’s point of view. Everything still runs locally in your browser — your files are never uploaded.
Works properly on phones and tablets
The toolbar now fits small screens, the layer list and board properties open as slide-in panels, and you can pan with one finger and pinch to zoom on the board.
Saved projects now reopen with the board
Saving to the browser or exporting a .gvproject file now stores the Gerber files themselves, so a project reopens exactly as you left it — layers, colours and visibility included. Saved projects are listed in the Project menu, where you can open or delete them.
Pick up where you left off
If you close the tab by accident, the viewer offers to restore your last board the next time you visit.
Real example board
“Load example” now opens a complete sample PCB (copper, mask, paste, silkscreen, outline and drills) instead of a simplified drawing, so you can try every tool before opening your own files.
Image export includes every visible layer
Exporting PNG or SVG in Layers view now saves all visible layers stacked with their colours, not just the first layer.
Drill table
The properties panel now lists every drill size with its hole count, and the minimum drill size is taken from your actual drill file.
Clear messages when a file can’t be read
Instead of failing silently, the viewer tells you when no valid Gerber data was found, and lists any files in a ZIP it had to skip.
Any file name, any extension
The file picker no longer hides files with uncommon extensions (for example .art, .pho, .cmp or .txt drill files), so exports from more CAD tools can be opened.
Clearer layer names
Layers are shown with readable names such as “Top Copper” or “Inner Copper” in your language, instead of internal labels.
Keyboard shortcuts
V = select, H = pan, M = measure distance, A = measure angle, F = fit to screen.
Proper naming dialog
Saving or exporting a project now opens a small in-page dialog for the project name instead of a browser pop-up.
Embed a specific board
The free embed code can now point at a public Gerber ZIP link, so the embedded viewer opens that board automatically.
Nothing hidden behind the bottom banner
The viewer now leaves room for the bottom banner, so status information and controls at the bottom of the screen are no longer covered.
