Batch Processing Techniques
1. Automated Conversion Workflows
Process thousands of product images automatically with these methods:
# Convert all JPGs to WebP (Linux/Mac)
find ./products -name "*.jpg" -exec cwebp -q 85 {} -o {}.webp \;
# Windows PowerShell equivalent
Get-ChildItem -Path ./products -Filter *.jpg | ForEach {
cwebp -q 85 $_.FullName -o ($_.DirectoryName + "/" + $_.BaseName + ".webp")
}
2. CI/CD Pipeline Integration
Add image optimization to your deployment process:
# Sample GitHub Actions workflow
name: Image Optimization
on: [push]
jobs:
optimize:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Optimize images
run: |
sudo apt-get install webp
find ./products -name "*.jpg" -exec cwebp -q 85 {} -o {}.webp \;
- uses: actions/upload-artifact@v3
with:
name: optimized-images
path: ./products/*.webp
