How it works
Click 'Upload files' and select any video or audio file from your device. All common media formats are supported.
Choose a custom speed (0.10x to 5x) from the dropdown, or enter a target duration in seconds — use one at a time.
Hit 'Submit'. Your speed-adjusted file is ready in seconds. Preview it directly or download it instantly.
