SM Recorder

Capture
Your browser chooses the screen, tab or window. Shared audio depends on browser, operating system and selected source. Headphones help prevent echo.
Ready
Recordings are held in memory. Download before leaving. Saved files plus new encoded buffers share a 256 MiB budget; sessions stop after 15 minutes. Browser decoding, encoding and temporary copies need additional memory, so large captures may exhaust memory sooner.Review recording
Selection changes preview playback only. Download contains the full recording.
Export creates a separate WebM by replaying and re-encoding the selection. It takes about the selection's duration and uses approximate cut edges. Keep this page active; export stops at 128 MiB or the remaining shared capacity. A failed or cancelled export preserves existing downloads. Decoded audio is captured without playing through speakers; support depends on the browser.
Requires a secure browser context (HTTPS). Screen capture and picture-in-picture support vary by browser; mobile browsers commonly lack screen capture. No upload or SM Player transfer is performed.
