Bulk Upscaling
What is Bulk Upscale?
The bulk upscale feature lets you enhance multiple coloring pages at once by increasing their resolution and improving image quality. Instead of upscaling images one by one, you can select up to 50 images and process them simultaneously in the background.
How It Works
The system uses advanced AI upscaling technology to:
Double the resolution - Transform 512x512 images to 1024x1024 (or similar scaling)
Preserve coloring page style - Maintains clean black and white line art
Process in parallel - All selected images are enhanced simultaneously
Using Bulk Upscale
Step 1: Select Your Images
Go to your dashboard
Click the checkbox next to each image you want to upscale
Select up to 50 images per batch
Step 2: Start the Upscale Job
In the contextual menu at the bottom of your screen, click the "Upscale" icon
Confirm your selection
The job will start processing immediately

Step 3: Monitor Progress
Your bulk upscale job will appear in the bulk actions dashboard showing:
Total images being processed
Real-time progress as images complete
Individual image status (pending, processing, completed, failed)
Step 4: Download Results
Once complete, you can:
View individual images by expanding the job card
Download all images as a ZIP file using the bulk download button
Image Requirements
Supported Images
Coloring pages generated through ColorBliss
PNG and JPEG formats
Maximum 4MB file size per image
Limitations
Images already upscaled cannot be processed again
Very large images (>4MB) will be skipped
Corrupted or invalid images will fail individually without affecting other images
You will not have any credits deducted for failed upscaling.
Technical Details
Processing Time
Most jobs finish in a few minutes.
Processing time varies based on:
Original image complexity
Current system load
Network conditions
Quality Enhancement
The upscaling process:
Maintains crisp edges and clean lines
Preserves the black and white coloring page aesthetic
Print Quality & DPI
One of the biggest benefits of upscaling is improved print quality:
Higher DPI for printing - Upscaled images reach approximately 350 DPI when printed at standard sizes
Professional print quality - Meets commercial printing standards (300+ DPI requirement)
Crisp lines on paper - No pixelation or blurry edges when printed
Perfect for large formats - Upscaled images can be printed up to 8x10 inches with excellent quality
Troubleshooting
Job Stuck at "Processing"
If your job appears stuck:
Wait 5-10 minutes as processing can take time
Refresh your browser to check for updates
Contact support if stuck for over 30 minutes
Individual Image Failures
Some images may fail while others succeed:
File too large: Original image exceeded 4MB limit
Already upscaled: Image was previously processed
Invalid format: Corrupted or unsupported file
Processing error: Temporary AI service issue
Failed images don't affect successful ones in the same batch.
Download Issues
If downloads fail:
Check your internet connection
Try downloading individual images instead of the bulk ZIP
Clear browser cache and try again
Contact support for persistent issues
Best Practices
Batch Sizing
Start small: Try 5-10 images for your first batch
Monitor progress: Larger batches take significantly longer
Consider timing: Run large batches during off-peak hours
Image Selection
Choose wisely: Select your best coloring pages for upscaling
Check quality: Ensure original images are clear and well-formed
Avoid duplicates: Don't upscale the same image multiple times
