.oga files. Batch is supported, and the cut runs on our servers — files are not posted to a public folder.HH:MM:SS.sss from the dropdown. Default is start 0 with a 10-second duration; change either value to grab the exact slice you need..oga; FLAC, Opus, and Speex are also valid inside the Ogg container). Set Constant Bitrate (8–384 kbps) or Variable Bitrate (48–384 kbps), choose a Quality Preset from Lowest to Highest, force Mono/Stereo channels, or set a Sample Rate (8000–48000 Hz). Leave everything on default and the kept audio is re-encoded in the source codec at close to the source bitrate — inaudible in practice..oga extension and downloads straight to your device — no sign-up, no watermark, uploaded only to xconvert’s own servers, auto-deleted after a few hours..oga is the IETF-standard extension for audio-only Ogg files, defined in RFC 5334 (September 2008). Per the spec, .oga may carry Vorbis, FLAC, Speex, or Opus inside an Ogg container, while the older .ogg extension is reserved for Vorbis-only streams. Cutting an .oga lets you keep the open-format pedigree (no patent fees, no DRM) while trimming dead air, extracting a single track, or shortening a long recording.
.oga is lossless, so a FLAC-to-FLAC cut preserves the audio samples exactly. Useful for extracting a 30-second sample from a live concert recording while the master stays untouched..oga). Cut sound effects to exact loop points and keep them in their native container..oga (per Wikimedia's Ogg-first policy). Trim a single word from a longer phrase for use in a language deck.####.oga vs.ogg vs.opus — When Each Extension Applies
| Property | .oga | .ogg | .opus |
|---|---|---|---|
| Defined by | RFC 5334 (2008) | RFC 3534 / 5334 | RFC 7845 (2016) |
| Container | Ogg | Ogg | Ogg (Opus-only) |
| Codecs allowed | Vorbis, FLAC, Speex, Opus | Vorbis only (per spec) | Opus only |
| MIME type | audio/ogg |
audio/ogg |
audio/opus |
| Ogg Skeleton stream | Recommended | Not required | n/a |
| Best fit | Mixed-codec or FLAC/Speex audio | Legacy Vorbis playback | Modern voice + low-latency |
| Codec | Typical bitrate | Best for | Notes |
|---|---|---|---|
| Vorbis | 96–256 kbps (VBR) | Music, general audio | Default for .oga. Audacity quality 0–10 maps to VBR (default 5 ≈ 160 kbps). |
| FLAC | ~700–1100 kbps | Archival, lossless masters | Bit-perfect; file size is 50–70% of WAV. |
| Opus | 16–128 kbps | Voice + music in one codec | Excellent under 64 kbps; IETF standard since 2012. |
| Speex | 4.75–24 kbps | Narrow/wideband speech only | Deprecated by Opus in 2012 but still decoded everywhere. |
The cut is sample-accurate, and the kept audio is re-encoded in the source codec. For FLAC that is lossless — the samples come out unchanged. For Vorbis, Opus, and Speex the re-encode runs at close to the source bitrate: one high-bitrate generation is inaudible in practice, but it is a re-encode, not a bit-perfect packet copy. Changing the codec or bitrate re-encodes at your new settings instead.
It shouldn't — the audio is decoded at your timestamps, so the cut is sample-accurate rather than snapping to a ~23 ms Vorbis frame or 20 ms Opus packet boundary. A request for "start at 1.234 s" starts at 1.234 s. If a cut seems offset, double-check whether you entered plain seconds or HH:MM:SS.sss.
.ogg is reserved by RFC 5334 for Ogg files containing only a Vorbis bitstream (kept for backwards compatibility). .oga is the modern, IETF-recommended extension for any audio-only Ogg file — including Vorbis, FLAC, Speex, or Opus — and "SHOULD have an Ogg Skeleton logical bitstream" per the spec. In practice, browsers and players accept both extensions interchangeably for Vorbis audio.
Yes. FLAC-in-Ogg (.oga) cuts with no quality loss because FLAC is lossless — the kept audio is rewritten as FLAC with identical samples. If you switch codecs, pick FLAC again from the dropdown to keep the master quality. Note that the native .flac container is more widely supported by hardware players than FLAC-in-Ogg — convert if you hit playback issues.
Apple's ecosystem still does not ship native Ogg/Vorbis decoders. macOS and iOS Safari decode .oga/.ogg Vorbis only when the page uses a JavaScript decoder. If your audience is iPhone/iPad-heavy, convert to OGA → MP3 or OGA → M4A after the cut. Chrome, Firefox, Edge, and Android Chrome have decoded .oga Vorbis natively for over a decade.
Yes — drop a folder's worth of .oga files at once and set start/duration. Every file is cut with the same parameters and downloads as a single zip when the batch finishes. If you need different cut points per file, run them individually or use the Audio Cutter which handles per-file cue points.
Leave the Codec dropdown on the source codec (Vorbis if your file is Ogg Vorbis), leave Bitrate/Quality Preset on Original/Unchanged, and leave Sample Rate and Channels untouched. Set only start time and duration. The clip keeps the source codec, sample rate, and channel layout — re-encoded at close to the source bitrate — and shrinks by roughly the duration ratio.
XConvert processes .oga files on our servers, so the practical ceiling depends on your upload bandwidth. Most laptops handle multi-hour FLAC-in-Ogg files (1–2 GB) without trouble; phones do best under 200 MB. If you need to cut a very large file, trim the OGA first to a coarse range, then refine.
Both keep a single section of the file. "Cut" is the action verb most editors use, and our tool treats them as synonyms — same engine, same options. If you want to remove a middle section (keep the head AND tail), do two passes or use a full audio editor like Audacity. To convert formats during the cut, change the codec dropdown in step 3 or use the relevant OGA conversion tool afterwards.
