Cut OGG

How to Cut OGG Audio Online

1. Upload Your OGG File: Drag and drop or click "Add Files" to select OGG files — WhatsApp voice notes (.opus inside .ogg), game audio assets from Unity / Godot projects, podcast downloads, browser audio captures, or music tracks ripped to Vorbis. Batch is supported, drop in several files and apply the same cut range to each.
2. Set Start Time and Duration: Enter a start time and a duration to keep. Both fields accept seconds (12.5) or HH:MM:SS.sss format (00:01:30.500) for millisecond precision. Add multiple cut ranges to extract several clips from one OGG in a single pass — each pair produces its own output file.
3. Pick Output Codec and Quality (Optional): Default keeps the source stream untouched (Vorbis stays Vorbis, Opus stays Opus) for a stream-copy result with zero quality loss. Switch to re-encode to change codec (Vorbis, Opus, FLAC, MP3, AAC, AC3, PCM, Speex, WavPack), pick a quality preset (Highest → Lowest), set constant bitrate (8-320 kbps) or variable bitrate, choose sample rate (8000-48000 Hz), or switch between Mono and Stereo.
4. Cut and Download: Click Cut. Files process in your browser session — download individually or as a ZIP. No sign-up, no watermark, no upload to a server.

Why Cut OGG Files?

OGG is the open, royalty-free container the Xiph.Org Foundation built in the late 1990s — it usually wraps Vorbis (music, game audio, podcasts) or Opus (voice, low-latency streaming, WhatsApp voice notes). Because it's patent-free, OGG is the default audio format for most game engines, Wikipedia's audio uploads, and a lot of Linux desktop software. Cutting OGG is useful for:

• WhatsApp voice note edits — WhatsApp sends voice messages as Opus-in-OGG (.opus extension on export, but the bytes are an Ogg container). Trim out the long pause at the start, the "wait, let me try that again" before the actual message, or the dead silence after you forgot to stop recording.
• Game audio for Unity, Godot, and Unreal — Unity, Godot, and many other engines accept OGG Vorbis natively for music and sound effects. Cut a long ambient recording into a seamless 30-second loop, slice a single voice-over take into per-line clips, or extract a footstep from a longer foley capture.
• Podcast highlights and quotes — Some indie podcast feeds publish OGG instead of MP3 to save bandwidth. Pull a 60-90 second highlight to share on Mastodon, Slack, or a blog post without re-hosting the whole episode.
• Music clips and loops — Bandcamp lets artists download purchases as Vorbis OGG. Cut a chorus-only clip for a playlist preview, a 15-second hook for a short video, or trim an album track to its instrumental intro.
• Sharing under chat caps — Discord's free 10 MB cap, WhatsApp's 16 MB media cap, and Slack's 1 GB-but-please-don't cap all benefit from a quick trim. A 10-minute Vorbis OGG at 128 kbps runs about 9 MB — cut to the part that matters and it fits anywhere.
• Wikipedia and Wikimedia uploads — Wikipedia accepts OGG and OPUS but not MP3 (patent reasons, historically). Trim a pronunciation example, a public-domain music excerpt, or a spoken-article narration to the exact span before uploading.

For a different output format after cutting, see OGG to MP3, OGG to WAV, or OGG to Opus.

Stream Copy vs Re-encode — When to Use Which

Property	Stream copy (default)	Re-encode
Speed	Very fast (seconds for any size)	Proportional to clip length
Quality	Bit-identical to source Vorbis / Opus	Slight loss unless preset is Highest
Output codec	Same as source (Vorbis stays Vorbis, Opus stays Opus)	Any supported (Vorbis, Opus, FLAC, MP3, AAC, AC3, PCM, Speex, WavPack)
Cut precision	Snaps to nearest Ogg page boundary	Sample-accurate
Output container	OGG	OGG (or change container by routing through a converter)
File size	Same proportion as duration kept	Variable by bitrate / quality settings
Best for	Quick lossless extraction, WhatsApp voice notes, game-asset trimming	Sample-accurate cuts, codec change, smaller file

Vorbis and Opus are both perceptual lossy codecs, so re-encoding either of them back to itself adds a small generation loss. Stream copy avoids that entirely — the kept audio is byte-identical to the corresponding portion of the source.

OGG Codec and Bitrate Quick Guide

Use case	Codec	Bitrate	Notes
WhatsApp voice notes	Opus	~24 kbps mono	What WhatsApp actually sends; tiny file, clear voice
Spoken word / podcast	Opus or Vorbis	48-64 kbps mono	Opus wins below 64 kbps; Vorbis fine for older players
Game sound effects	Vorbis	96-128 kbps stereo	Engine-friendly default; balances size and clarity
Music streaming	Vorbis	128-192 kbps stereo	Spotify-OGG-Vorbis range; transparent for most listeners
Music archival	Vorbis	256-320 kbps stereo	Highest Vorbis quality, or switch to FLAC for true lossless
Low-latency live audio	Opus	64-96 kbps stereo	Opus's design target; Discord's voice codec

Opus generally outperforms Vorbis at every bitrate below ~96 kbps and matches it above. Vorbis is still common because it's the older, more broadly supported codec.

Frequently Asked Questions

Will cutting reduce my OGG file's audio quality?

Not in stream-copy mode (the default). XConvert writes the original Vorbis or Opus packets into a new Ogg container without decoding or re-encoding — the cut output is bit-identical to the corresponding portion of the source. That matters specifically for Vorbis and Opus because both are lossy codecs, and re-encoding lossy-to-lossy adds a generation of perceptual loss each pass. Quality only changes if you opt into re-encode to switch codec, drop the bitrate, or shrink the file. Pick the Highest preset and the loss is inaudible.

Can I cut a WhatsApp voice note here?

Yes. WhatsApp voice messages are Opus audio inside an Ogg container — the file usually arrives as .opus, but the bytes are the same Ogg format this tool handles. Drop the .opus file in (or rename to .ogg if the upload form is strict), set start time and duration, and download the trimmed voice note. Stream-copy keeps the Opus stream untouched so the result still plays back in WhatsApp, Telegram, and any other Opus-capable app.

What's the difference between OGG, OGA, and OPUS file extensions?

All three are the same Ogg container; the extension just signals what's inside. .ogg is the catch-all (often Vorbis audio, sometimes video). .oga is the audio-only convention introduced to disambiguate from Ogg-with-video. .opus signals the audio is specifically Opus. XConvert treats them the same — see OGG to OGA or OGG to Opus if you need the extension changed.

How precise is the cut on an OGG — can I land on the exact sample?

Stream-copy snaps to the nearest Ogg page boundary, which is typically a few tens of milliseconds for Vorbis and around 20 ms (one Opus frame) for Opus. For voice notes, podcasts, and most music edits that's already inaudibly close to where you asked. If you need a true sample-accurate cut (de-clicking, syncing to a specific transient in a game audio loop), enable re-encode in step 3 — the output is decoded and re-encoded from your exact timestamp.

Can I extract multiple clips from one OGG in a single pass?

Yes. Add multiple cut ranges — each pair of start time + duration produces a separate output file. Useful for splitting a long Bandcamp album rip into per-track files, pulling several voice-over lines from a single recording session, or breaking a 90-minute podcast into chapter-sized chunks.

What's the maximum OGG file size or length I can cut?

There's no fixed cap. Cutting runs in your browser, so the practical limit is your device's available memory. Multi-hour Vorbis podcasts, full-album archival rips, and long Twitch VOD audio extractions all work. Stream-copy mode is fast enough that even multi-hundred-MB files cut in seconds once uploaded.

Will the cut OGG still play in Firefox, Chrome, and VLC?

Yes. Stream-copy preserves the Vorbis or Opus stream and rewraps it in a fresh Ogg container that follows the spec — every player that read the source plays the output. Firefox has shipped native Ogg Vorbis playback since 2009, Chrome since 2010, and VLC has handled Ogg from day one. Opus playback is universal in modern browsers and on Android. Safari is the one holdout — see OGG to MP3 if you need Safari/iOS compatibility.

Should I cut first or convert OGG to MP3 first?

Cut first, always. Stream-copy cutting is essentially free (seconds) and lossless, and shrinks the file before the slower transcode step. A 30-second clip pulled from a 90-minute OGG converts to MP3 about 180× faster than transcoding the full hour-and-a-half and trimming the MP3 afterward. See OGG to MP3 for the conversion step.
