Questions
Are the tools really free?
Yes. They are free, need no account and have no usage limit on our side.
Do the tools upload my artwork?
No. Tools that read an image do it in your browser to get its size; the file never leaves your device.
What do the tools have to do with WallMock?
They answer the questions sellers ask before listing: print sizes, resolution, frames and wall layouts. WallMock then shows your exact artwork in realistic rooms for the listing photos.
