★ Trim Video / Audio
Free online video & audio trimmer
Cut the exact part you need from a video or audio file — a short clip, or an MP3 ringtone — processed entirely in your browser.
Upload a video or audio file (MP3…) to cut the part you need
Need to cut a video down to just the good part, or turn a song into a short ringtone? This tool plays your file right in the page so you can preview it, set the start and end points exactly where you want, and cuts it in seconds — no re-encoding, so it stays fast even on long files.
Works with both video (MP4, MOV, WEBM…) and audio (MP3, M4A, WAV…) using the same tool — the output keeps the original format, so a video stays a video and an MP3 stays an MP3.
Why use this trimmer?
Fast, no re-encoding
Cuts the stream directly instead of re-compressing, so even a large file trims in seconds.
Works for video and audio
Trim a video clip or cut an MP3 for a ringtone — same tool, same simple steps.
100% private
Your file is processed on your own device — nothing is ever uploaded anywhere.
Frequently asked questions
Can I use this to make a ringtone from a song?
Yes — upload the MP3, set the start and end of the part you want, and download the trimmed clip.
Is the cut point exactly where I set it?
For audio, yes, essentially exact. For video, since no re-encoding happens (for speed), the cut may shift slightly to the nearest keyframe — usually under a second.
Is my file uploaded anywhere?
No. Trimming happens entirely on your device using WebAssembly — nothing is sent to a server.
What formats are supported?
Most common video (MP4, MOV, WEBM, MKV) and audio (MP3, M4A, WAV, AAC) formats.
