Batch Image Processing: Convert & Compress Multiple Files
Processing images one by one is tedious. Learn how to handle dozens or hundreds of images efficiently with batch processing.
Pictey Supports Batch Processing
All Pictey tools support multiple file uploads. Process dozens of images at once, download as ZIP.
Try Batch ProcessingWhat is Batch Processing?
Batch processing means applying the same operation to multiple files at once. Instead of converting images one at a time, you upload all files and process them together with identical settings.
When to Use Batch Processing
- Photo shoots: Convert hundreds of RAW photos
- Website migration: Optimize all images for new site
- E-commerce: Resize product images to consistent dimensions
- Archives: Convert old formats to modern ones
- Social media: Prepare images for multiple platforms
How Batch Processing Works in Pictey
Step 1: Select Multiple Files
When uploading, select multiple files at once (hold Ctrl/Cmd while clicking), or drag and drop an entire folder of images.
Step 2: Configure Settings
Choose your desired output format, quality, or dimensions. These settings apply to all uploaded files.
Step 3: Process
Click the process button. All images are converted/compressed simultaneously in your browser.
Step 4: Download
Download individual files or all files as a ZIP archive. File names are preserved with the new extension.
Batch Processing Tips
Batch processing works best when all images need the same treatment. Group similar images together.
Before processing 100 images, test your settings on 3-5 to ensure the results are what you expect.
Always keep your original files. Download processed images to a different folder.
Name source files consistently. Output files preserve original names with new extensions.
Common Batch Operations
Batch Format Conversion
Convert all images from one format to another. Common use cases:
- HEIC → JPG (iPhone photos for Windows users)
- PNG → WebP (web optimization)
- WebP → JPG (universal compatibility)
- RAW → JPG (photography workflow)
Batch Compression
Reduce file sizes across all images simultaneously. Great for:
- Website optimization (faster load times)
- Email attachments (stay under size limits)
- Cloud storage (save space)
- Archive preparation (smaller backups)
Batch Resizing
Resize all images to consistent dimensions. Perfect for:
- E-commerce product photos
- Social media content preparation
- Thumbnail generation
- Print preparation
Browser-Based vs. Desktop Software
Browser-Based (Pictey)
- No installation required
- Works on any device with a browser
- Privacy: files stay on your device
- Always up to date
- Limited by browser memory for very large batches
Desktop Software
- Better for thousands of images
- More advanced features
- Requires installation and updates
- Often expensive (Photoshop, Lightroom)
How Many Files Can I Process?
Pictey can handle 20-50 images comfortably on most devices. For larger batches, process in groups to avoid browser memory limits.
Workflow Example: Website Migration
You're moving to a new website and need to optimize 200 images:
- Sort images by type: Photos in one folder, graphics in another
- Process photos: Convert to WebP at 80% quality
- Process graphics: Keep as PNG but compress losslessly
- Resize if needed: No image wider than 1920px
- Test: Check a few images on the new site
- Upload: Replace old images with optimized versions
Privacy First
Pictey processes all images in your browser. Your files are never uploaded to any server, making it safe for sensitive content.
Conclusion
Batch processing transforms hours of manual work into minutes. Whether you're optimizing website images, preparing photos for sharing, or converting file formats, processing multiple files at once is the efficient approach.
