WEBM INPUT / JSON TRANSCRIPT EXPORT
Convert WEBM speech to JSON
FROM RECORDING TO EDITABLE TEXT
From WEBM speech to an editable JSON download
Upload a compatible .webm recording with audible speech, review the transcript after processing, and open Download to save JSON.
Upload the recording directly from your computer.
Long audio continues processing while you are away.
Return to searchable text with timestamps and exports.
Use genuine WEBM media, not a renamed recording
The direct uploader accepts filenames ending in .webm. Typical inputs include browser recordings, screen captures or online presentations. Screen text and graphics are not transcribed; audible speech is. Audio decoding depends on the underlying codec and the recording, not on the extension alone.
What the JSON download contains
The output is a structured JSON transcript based on recognized speech. It is designed for automated notes, parsing and data workflows. Json represents transcript segments/metadata, not decoded media bytes. The source recording is not altered by downloading this file.
Review the words before sharing
Listen back to the original WEBM recording and inspect proper names, numerical values, jargon and background speech. Automatic segment times and speaker turns may need revision.
Use the same transcript in other formats
One completed transcription can also be downloaded in TXT, DOCX, SRT, VTT and JSON. You do not need to submit the recording five times to obtain different export types.
How to turn WEBM speech into JSON
- Choose an authorized .webm video recording containing audible speech. The quick form displays its file-size limit; larger eligible Premium recordings require the main app's chunked uploader.
- Upload to begin AI speech-to-text. Wait for the job to finish, then check people, numbers and timestamps in the transcript.
- On the completed job, open Download on the completed job and select JSON. The download is a structured JSON transcript.
Format warning: Screen text and graphics are not transcribed; audible speech is.
Export detail: JSON represents transcript segments/metadata, not decoded media bytes. A recording without understandable speech cannot yield meaningful transcript text.
Free account: 60 transcription minutes across 20 jobs per month, subject to per-job, file-size and source restrictions. Trying without an account can return a shortened preview instead of a full downloadable job.
Browse all supported input/output formats. For large recordings, go through the main uploader; you can select the same export format after processing.
Frequently asked questions
Can I upload a file in WEBM format and download JSON?
Yes, if the .webm video recording is decodable and contains understandable speech, and the job completes within your limits. Afterward, open Download on the completed job and select JSON.
Does WEBM to JSON change the original media?
No. The output is a structured JSON transcript generated from spoken words; it is not a byte-for-byte media format conversion.
Why might an upload of WEBM fail?
Screen text and graphics are not transcribed; audible speech is. The recording can also exceed the upload, duration or account limits. Try a small unprotected file first.
Can I get JSON for free?
An account includes 60 minutes and 20 jobs per month, with source/file restrictions. An anonymous try can be preview-only; do not assume every export is available without a completed job.
Can I also export my WEBM transcript as another format?
Yes. The same completed job has TXT, DOCX, SRT, VTT and JSON download options, subject to normal access restrictions.
