Pricing
from $5.00 / 1,000 file converteds
FFmpeg API for AI agents and automations. Send a media URL, get MP3, WAV, Whisper-ready 16 kHz mono WAV, FLAC, OGG, M4A, MP4, WebM, GIF or a JPEG thumbnail back. Trim and batch. No ffmpeg, Docker or server. Works via MCP, n8n, Make, API. Failed files are free.
Direct, publicly downloadable URL of ONE audio or video file (http/https; redirects followed). Any FFmpeg-readable format: mp4, mov, mkv, webm, avi, mp3, wav, m4a, ogg, flac, opus... Max 2 GB. Must be the file itself, not a YouTube/web page. Example: https://download.samplelib.com/mp4/sample-5s.mp4
Output format, applied to url and to any files item without its own target. Default: mp3. Audio: mp3 (VBR ~190 kbps), wav (16-bit PCM, original rate), wav16k (mono, 16 000 Hz, 16-bit PCM - use this before Whisper/speech-to-text), flac (lossless), ogg (Vorbis), m4a (AAC 192 kbps). Video: mp4 (H.264 + AAC, web/faststart), webm (VP9 + Opus). Image: gif (animated, 8 fps, 360 px wide, no audio), thumbnail (single JPEG frame at startSeconds, default first frame). Audio targets need an input audio stream; video/gif/thumbnail need a video stream.
Optional trim start in whole seconds from the beginning of the input, e.g. 30. For target=thumbnail this is the frame time (default: first frame). Applies to url and acts as the default for every files item; a files item's own startSeconds overrides it (and may be fractional, e.g. 12.5).
Optional length in whole seconds to keep from startSeconds, e.g. 600 for 10 minutes. Billing is per started minute of OUTPUT, so trimming lowers cost; also lets inputs longer than maxDurationSeconds be processed. Applies to url and is the default for every files item; per-item durationSeconds overrides it.
Optional batch, processed sequentially. Array of objects: {"url": string (required), "target": one of the target values (optional, falls back to top-level target), "startSeconds": number (optional, seconds from start to begin, e.g. 30; falls back to top-level startSeconds), "durationSeconds": number (optional, seconds to keep, e.g. 60; falls back to top-level durationSeconds)}. Example: [{"url":"https://example.com/talk.mp4","target":"wav16k"},{"url":"https://example.com/clip.mov","target":"gif","startSeconds":5,"durationSeconds":4}]. Plain URL strings are also accepted. Failed items return status=error and are not charged.
Safety cap in seconds on input duration (default 10800 = 3 hours). Longer inputs are rejected with status=error (not charged) unless durationSeconds is set (top-level or on the item) to trim. Billing is per started minute of OUTPUT, so trimming also lowers cost.
