JPG to MP4 API - Convert JPG to MP4 API: Pricing, Documentation
by Pixazo
The JPG to MP4 API wraps a still JPG in a standards-compliant MP4 container. It is deterministic, not generative: the photo is held on screen, unchanged, for as long as you ask, and the result is a silent H.264 video. That is exactly what you want when something downstream will only accept a video file — a social feed that rejects images, a timeline that needs a hold, a signage player whose playlist is video-only. Send an image_url and a duration, poll the job, download the MP4. Prefer a no-code option? The same conversion is available free in your browser as the JPG to MP4 Converter.

Ocp-Apim-Subscription-Key | Yes | Your Pixazo API key |
JPG to MP4 generate request
Plenty of systems will not take a still. Ad slots, story formats, broadcast timelines and signage players all want a video file, and the usual answer is to open an editor and export a five-second hold by hand. The JPG to MP4 API does that one step over HTTP: it decodes your JPG, holds it for the duration you choose, and encodes a silent H.264/yuv420p MP4 with even dimensions and correct headers, downscaled to fit within 1920x1920 if the source is larger and never upscaled if it is smaller. Nothing is added and nothing moves — no motion, no prompt, no model. It is a container change, priced like one at a flat $0.002 per clip.
Endpoint: POST https://gateway.pixazo.ai/media-tools/v1/image-to-video
Request Code
curl -X POST 'https://gateway.pixazo.ai/media-tools/v1/image-to-video' \
-H 'Ocp-Apim-Subscription-Key: YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"image_url":"https://example.com/input.jpg","duration_seconds":5}'Output
{
"request_id": "req_9f3c1a7b2e",
"status": "QUEUED",
"polling_url": "https://gateway.pixazo.ai/v2/requests/status/req_9f3c1a7b2e"
}Webhook (Optional)
Instead of polling, include a webhook_url in the request body and Pixazo will POST the completed job payload to that URL when the conversion finishes. The webhook body is identical to the completed-status response shown under Retrieving Results.
Request Parameters
| Parameter | Required | Type | Default | Allowed | Description |
|---|---|---|---|---|---|
image_url | Required | string | — | HTTP(S) URL | Publicly reachable URL of the source still. jpg, png, webp, avif, heic, tiff, bmp, gif and SVG are accepted; the source must be under 50 megapixels. |
duration_seconds | Optional | number | 5 | 1 – 60 | How long the still is held on screen, in seconds. Does not affect the price. |
webhook_url | Optional | string | — | HTTP(S) URL | Receive the completed job via webhook instead of polling. |
Example Request
curl -X POST 'https://gateway.pixazo.ai/media-tools/v1/image-to-video' \
-H 'Ocp-Apim-Subscription-Key: YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"image_url":"https://example.com/input.jpg","duration_seconds":5}'Response
Every request returns a request_id immediately with a QUEUED status. Use the polling_url (or a webhook) to retrieve the finished file.

Response Handling
The submit call returns one of the HTTP status codes below. A 202 means the job was accepted — everything else is an error you should handle.
| Code | Meaning |
|---|---|
| 202 | Accepted — the job was queued; poll the status URL. |
| 400 | Bad request — a parameter is missing or invalid. |
| 401 | Unauthorized — missing or wrong API key. |
| 402 | Payment required — insufficient balance. |
| 429 | Too many requests — you are being rate-limited. |
| 500 | Server error — transient; retry with backoff. |
Error Responses
Errors return a JSON body with a machine-readable code and a human-readable message.
