What is Batch Processing?

Batch processing allows you to apply the same edits, adjustments, or transformations to multiple images at once, instead of editing them one by one. This powerful feature can save you hours of repetitive work.

Key Features

  • Process hundreds of images in a single operation
  • Apply consistent edits across all photos
  • Maintain quality with professional processing
  • Save time on repetitive tasks
  • Preserve originals with non-destructive editing

When to Use Batch Processing

Batch processing is perfect for:

E-commerce: Resize product photos to consistent dimensions
Photography: Apply the same color correction to an entire shoot
Social Media: Compress multiple images for faster uploads
Web Development: Convert images to WebP format for better performance
Portfolio: Add watermarks to all photos simultaneously
Archive: Rename and organize hundreds of files


Benefits of Batch Processing

1. Save Time

Instead of editing photos one by one:

  • Manual: 2 minutes per photo × 100 photos = 3.3 hours
  • Batch: 30 seconds setup + 2 minutes processing = 2.5 minutes

Time savings: 99% faster!

2. Consistent Results

Batch processing ensures:

  • All images have the same dimensions
  • Colors and brightness are uniform
  • File sizes are optimized
  • Naming conventions are consistent

3. Improved Workflow

  • Set it and forget it: Start batch processing and work on other tasks
  • Reduce errors: No risk of missing images or applying different settings
  • Streamline delivery: Clients receive perfectly formatted files
  • Focus on creativity: Spend less time on technical tasks

4. Professional Quality

Our batch processing maintains:

  • High image quality with smart compression
  • Accurate color profiles across all images
  • Proper metadata preservation

Troubleshooting

Problem: Images Look Over-Compressed

Symptoms: Blurry details, color banding, artifacts

  • Disable aggressive compression
  • Process fewer images at once

Problem: Processing Takes Too Long

Symptoms: Batch job runs for hours

Solution:

  • Reduce image count per batch
  • Lower output resolution
  • Use faster format (JPG vs PNG)
  • Check internet connection
  • Upgrade to Pro for faster processing

Problem: Colors Look Different

Symptoms: Batch processed images have wrong colors

Solution:

  • Check color profile settings
  • Use sRGB for web images

  • Test on target device

Problem: File Names Are Wrong

Symptoms: Output files have incorrect names

Solution:

  • Review naming pattern before processing
  • Use sequential numbering
  • Include date/project in prefix
  • Test with 1-2 files first

Problem: Some Images Failed

Symptoms: Not all images processed successfully

Possible Causes:

  • Corrupted image files
  • Unsupported format
  • File size too large
  • Network timeout
