Video/audio tools

Convert video to GIF, extract MP3 from MP4, trim/compress video, convert audio, and create iPhone ringtones

• Video → GIF Turn a section of an MP4, MOV, or WebM video into an animated GIF. Choose the size and frame rate, with palette optimization for sharper results.
• GIF → MP4 Converts a large GIF animation into a much smaller MP4 video. Useful for posting on places like Instagram or KakaoTalk that don't support GIF.
• MP4 → MP3 Extracts just the audio from a video (MP4, MOV, MKV, WebM) and saves it as MP3, M4A, or WAV. Great for pulling audio from lecture recordings or your own videos.
• Convert audio Convert audio files like MP3, WAV, M4A, AAC, OGG, FLAC, or AMR into the format you want. Choose the audio quality (bitrate) and mono/stereo.
• Trim video Cuts just the part you need from a video and saves it. Choose between fast trim (no re-encoding) and precise trim.
• Shrink video size Reduces file size by adjusting the video's resolution and quality. Supports targeting a specific size (e.g. 25MB) and removing audio.
• Create ringtone Trim the part you want (up to 40 seconds) from a music or recording file and turn it into an iPhone ringtone (M4R) or Android ringtone (MP3). Supports fade in/out.
• Capture video frame Save any moment from a video as a PNG or JPG at its original resolution, or capture several frames at once at a set interval.
• Speech-to-text (AI)Server AI (Whisper) transcribes speech from meeting recordings, lectures, interviews, and videos into text. Supports over 90 languages including Korean, and saves as TXT or SRT subtitles.
