What is a .LVF file?
The most common data format on the web.
An LVF file is a graphical resource used by the discontinued Logitech Webcam Software to overlay face effects (hats, glasses, moustaches, or full avatars) onto webcam video in real time. The software was discontinued around 2015 and does not run on Windows 10 or 11. There is no supported way to open LVF files in 2026; they are safe to delete.

Frequently asked questions
Is my .LVF file uploaded anywhere?
No. The file is opened directly from the copy you pick.
My .LVF file is invalid. Can you fix it?
We show the exact line and column of the first error. For common problems like comments, trailing commas, single quotes or Python-style True/False/None, click Try to repair and download the fixed file.
How large can the file be?
Up to 50 MB. The tree only builds the branches you open, so even multi-megabyte files stay responsive.
What is JSONPath?
A path like $.orders[3].customer.email that points to one value inside the data. Click any node to see its path and copy it for code, jq or your API docs.
Can I see my data as a table?
Yes. Any array of objects can be shown in the Table view and downloaded as CSV.
