批量转换AVIF 2026：快速处理1000+图片 [指南]

Why Bulk Conversion?

Converting images individually is tedious and time-consuming. Whether you're migrating a website, optimizing a photo library, or preparing assets for an app, bulk conversion saves hours of manual work.

• Website Migration: Convert hundreds or thousands of product images, blog photos, and assets simultaneously.
• Photo Libraries: Optimize personal or professional photo collections for storage savings.
• App Assets: Prepare UI elements, icons, and graphics in modern formats.
• Archive Optimization: Reduce storage costs by converting legacy image archives.

Online Tools (No Software Required)

For moderate batches, browser-based tools offer the simplest solution.

Our free AVIF.expert batch converter handles up to 10 images simultaneously, all processed locally in your browser. No upload required—your images never leave your device. Simply drag and drop multiple files, adjust quality settings, and download converted images individually or as a ZIP.

The browser-based approach works well for batches under 50-100 images. For larger volumes, command-line tools offer better efficiency.

Command Line Methods

For serious bulk conversion, command-line tools provide power and flexibility.

ImageMagick offers the simplest syntax for basic conversion. FFmpeg provides fine-grained control over encoding parameters. The official avifenc tool offers AVIF-specific optimizations.

# Using ImageMagick (cross-platform)
for file in *.jpg; do
  magick "$file" -quality 80 "${file%.jpg}.avif"
done

# Using ffmpeg (powerful options)
for file in *.png; do
  ffmpeg -i "$file" -c:v libaom-av1 -crf 30 "${file%.png}.avif"
done

# Using avifenc (official tool)
for file in *.jpg; do
  avifenc --min 20 --max 40 "$file" "${file%.jpg}.avif"
done

Automation Scripts

For recurring tasks, create scripts that handle conversion, organization, and cleanup.

#!/bin/bash
# Bulk convert with progress tracking

INPUT_DIR="./originals"
OUTPUT_DIR="./converted"
QUALITY=75

mkdir -p "$OUTPUT_DIR"
total=$(find "$INPUT_DIR" -type f \( -iname '*.jpg' -o -iname '*.png' \) | wc -l)
count=0

for file in "$INPUT_DIR"/*.{jpg,png,JPG,PNG}; do
  [ -f "$file" ] || continue
  filename=$(basename "$file")
  output="$OUTPUT_DIR/${filename%.*}.avif"
  
  magick "$file" -quality $QUALITY "$output"
  
  count=$((count + 1))
  echo "[$count/$total] Converted: $filename"
done

echo "Conversion complete! $count files processed."
