Conversion Presets

SnapOtter exposes 83 dedicated conversion preset endpoints in addition to the base converter tools. Each preset locks the output format and delegates to its base processing pipeline, so the behavior, validation, and output contract match the base tool listed below.

API Endpoint Pattern

POST /api/v1/tools/<section>/<presetId>

Send multipart/form-data with a file part and optional settings JSON string. Fast presets return 200 with a downloadUrl; long-running presets return 202 and progress streams from /api/v1/jobs/<jobId>/progress.

Notes

• Presets are first-class API endpoints and are also valid in batch requests where their base route supports batch processing.
• Presets that use video conversion can return 202 Accepted; connect to the job progress SSE endpoint before downloading the result.
• For advanced options not exposed by a preset, call the base converter tool directly and set the output format in settings.
