GLance by Jaime Mendoza

GLance lets you preview files before deciding whether you actually want them.

Click a link to a PDF, a spreadsheet or a Photoshop file and GLance opens it in a browser tab
instead of dropping it in your Downloads folder. If it wasn't what you were looking for, you
close the tab — nothing was saved, nothing to delete.

Everything happens inside your browser. There is no server, no account and no cloud service:
the rendering engines ship with the extension as WebAssembly. No file ever leaves your computer,
and GLance works offline.

• Works with files behind a login, and with export buttons that generate files on the fly
• Recent files list — filenames only, never contents, and can be turned off
• Automatic and manual modes: intercept the click, or show a small preview button next to links
• Right-click any link to preview it, even when the address gives no hint of its format
• English and Spanish interface, light and dark themes
