☕ AVI to WEBM with Java

Convert AVI videos to WebM format online for compatibility, delivery, and playback across devices and platforms.

JavaREST APIAVI → WEBM

Use this guide to convert AVI to WEBM with Java, then adapt the example to your own app, backend, or processing flow.

Overview

What this guide covers

Conversion path

Use Converterer to accept or prepare a AVI file, trigger a AVI to WEBM job, and return the output to your app or workflow.

Java example

Start with the example on this page, then adapt auth, file handling, polling, and result delivery to your environment.

Production usage

This is best suited to backend jobs, async processing, content pipelines, and repeatable conversion flows rather than one-off browser scripting.

Code example

AVI to WEBM

import okhttp3.*;
import java.io.File;

OkHttpClient client = new OkHttpClient();
String auth = Credentials.basic(
    System.getenv("CONVERTERER_API_KEY"),
    ""
);

RequestBody body = new MultipartBody.Builder()
    .setType(MultipartBody.FORM)
    .addFormDataPart(
        "input",
        "input.avi",
        RequestBody.create(
            new File("input.avi"),
            MediaType.parse("application/octet-stream")
        )
    )
    .addFormDataPart("output_format", "webm")
    .build();

Request req = new Request.Builder()
    .url("https://api.converterer.com/convert")
    .header("Authorization", auth)
    .post(body)
    .build();

try (Response res = client.newCall(req).execute()) {
    String json = res.body().string();
    // {"id":"...", "status":"queued"}
    // Result lands at <your-destination>/<id>.webm
}
