How to Edit a Video Online with BuffRadar

BuffRadar is a free-to-start online video editor that runs in your browser on any phone, tablet or computer. Upload a clip, then edit it by hand with a visual timeline or simply type what you want, and download the result as an MP4, a GIF or an MP3. There is nothing to install, and your exported videos carry no watermark.

Edit Videos Manually: Trim, Crop, Speed & Text

The manual editor works like a simple video app on your phone. Your clip plays in a live preview with a frame-by-frame timeline underneath and a tool bar at the bottom. Drag the blue handles to trim, tap a tool to change a setting, and check the result in the preview before you export. Every change can be undone and redone, so you can experiment freely.

Trim & Cut

Drag the handles to keep only the part you want, or cut a section out of the middle and the rest joins up automatically.

Crop & Resize

Switch to 9:16, 1:1 or 16:9 for Reels, Shorts, TikTok and YouTube. Fill the frame by cropping, or keep the whole video on a blurred background. Rotate, flip, and export at 1080p, 720p, 480p or 360p.

Speed & Reverse

Play from 0.5x slow motion up to 2x fast forward, or play a short clip backwards.

Audio & Music

Mute the original sound, set the volume anywhere from 0 to 200%, or add your own audio file as background music and loop it to fill the video.

Text & Stickers

Add a caption with your choice of size, colour, position and background box, plus emoji or your own image as stickers. Choose exactly when each one appears.

Filters & Effects

Black and white, warm, cool, vintage and vivid looks, brightness, contrast and saturation sliders, plus blur, sharpen, vignette and grain.

Fade & Cover

Fade the picture and sound in and out, and save any frame of your video as a JPG cover image.

Export as MP4, GIF or MP3

Download a standard MP4, a GIF of up to 30 seconds, or just the audio as an MP3.

Edit Videos with AI: Just Type What You Want

Don't want to fiddle with a timeline? Text to edit lets you describe the change in your own words. The AI turns your sentence into the right editing settings, applies them to your video and shows the result with a download button. It can trim and cut, crop to vertical or square, change speed, rotate, flip or reverse, mute or adjust the volume, add captions, apply filters and effects, add fades, and export a GIF or MP3. You can keep adding instructions, and each new request builds on the previous result. Adding music or stickers is done in the manual editor.
