Free online video tools
Cut, repair, convert and add to videos in your browser - subtitles, music, a steadier picture - without uploading them.
Video is the one kind of file people assume has to go to a server, because it is big and editing it sounds heavy. It does not. Modern browsers can decode, edit and encode video themselves, and every tool on this page does the work there, so a home video, a CCTV clip or a screen recording stays on your machine.
The Video Cutter trims and joins clips on a thumbnail timeline without re-encoding, and also crops to 9:16 or square, changes speed and reverses. The Video Compressor shrinks a video to fit Discord, WhatsApp or an email, converts AVI, WMV, FLV and VOB to MP4, pulls the sound out as MP3 and makes GIFs. Video Repair rebuilds an MP4 or MOV recording that was cut off and will not play or seek, and DAV to MP4 turns Dahua and Hikvision CCTV recordings into MP4s that play anywhere, without re-encoding and with the recording time kept.
To add to a video, Add Subtitles to Video makes captions from what is said, using a Whisper speech model downloaded the first time, and burns them in, word by word as on TikTok or as classic subtitles. Add Music to Video lays songs under a clip, mixed with its own sound or replacing it, the Slideshow Maker turns photos and a song into an MP4, the Video Stabilizer steadies shaky phone, GoPro and drone footage, and the Video Background Remover swaps the background behind a person for a colour, a blur or a picture. Blur Faces, from the image tools, works on video too.
The Screen Recorder records a screen, window or tab with your microphone and an optional webcam bubble, with no time limit and no watermark. For older and odder formats, the SWF Player plays Flash games and animations without Flash Player, and the Lottie and TGS Viewer plays Lottie animations and Telegram's animated stickers and saves them as GIF, MP4, WebM or PNG. All free, with no account.
