Audio, Video & Photo Tools
8 tools
For anyone who shoots, edits or just listens a lot. First the picture: remove the background from a photo, shrink and convert images, or pull the text out of a picture, all in your browser with nothing uploaded. Then the numbers: how big a video file will get, where text can sit without being covered by the app interface on a vertical video, whether your amp can drive your headphones, and how much of a photo will really be in focus.
