  2. The tool detects the target format (WEBM) and decodes the payload.
  3. Download the decoded output or use the text result for textual data.

Typical use cases

  • Restoring original files from API responses or logs with Base64 values.
  • Validating Base64 payloads before saving or passing to downstream services.
  • Decoding Base64 content into WEBM for immediate use.

Practical examples

Example 1: Base64 to WEBM

Input: data:video/webm;base64,GkXfo59ChoEBQveBAULygQ...

Output: decoded.webm

WEBM output is resolved automatically for preview/download flows.

Input: {"payload":"GkXfo59ChoEBQveBAULygQ..."}

Output: decoded.webm

Useful while debugging integration logs and queue consumers.

Edge cases

  • Payloads without correct Base64 padding (=) may be treated as corrupted.
  • Extra whitespace or line breaks inside Base64 often cause parse/decode failures.
  • When data URI MIME does not match actual WEBM content, output may open with a wrong app.

Common errors

Error: InvalidCharacterError

Cause: Input contains characters outside the Base64 alphabet.

Fix: Trim whitespace, remove invalid symbols, and retry decoding.

Error: Corrupted decoded file

Cause: Source payload was truncated while copying/transmitting.

Fix: Verify payload length against the original and resend full content.

Error: Wrong output extension

Cause: Declared MIME does not match expected WEBM content.

Fix: Use the matching format route or provide a correct data URI MIME.
