Quick Start 🚀

import { convertToAvifSync } from "nravif";
import fs from "fs/promises";

// Function to convert an image to AVIF format and save it to a file
async function convertAndSave() {
  try {
    // Define the input image file
    const inputFile = "input.jpg";
    // Define the output AVIF file name
    const outputFile = "output.avif";
    // Set AVIF conversion quality (0-100) and speed (0-10)
    const quality = 50;
    const speed = 4;

    console.log(`Converting ${inputFile} to AVIF format...`);

    // Convert the image to AVIF format, returns a Buffer
    const avifBuffer = await convertToAvifSync(inputFile, quality, speed);

    // Save the AVIF buffer to an output file
    await fs.writeFile(outputFile, avifBuffer);

    console.log(`✅ AVIF file saved successfully: ${outputFile}`);
  } catch (error) {
    // Handle any errors that occur during conversion or saving
    console.error("❌ Error converting image:", error);
  }
}

// Run the conversion function
convertAndSave();
