Events

The client supports event callbacks for tracking conversion progress:

Event: start

Emitted when conversion starts.

def on_start(data):
    print(f"Starting: {data['file_name']}")
    print(f"Converting {data['source_format']} to {data['target_format']}")

client.on('start', on_start)

Event: progress

Emitted at each step of the conversion process.

def on_progress(data):
    print(f"Step: {data['step']}")
    print(f"Message: {data['message']}")
    # data['step'] can be:
    # - 'requesting-upload-url'
    # - 'uploading'
    # - 'confirming'
    # - 'converting'
    # - 'downloading'

client.on('progress', on_progress)

Event: status

Emitted during polling for job completion.

def on_status(data):
    print(f"Status: {data['status']}")
    print(f"Attempt: {data['attempt']}/{data['max_attempts']}")

client.on('status', on_status)

Event: complete

Emitted when conversion completes successfully.

def on_complete(result):
    print('Conversion complete!')
    print(f"Output: {result['output_path']}")
    print(f"Size: {result['file_size']} bytes")
    print(f"Time: {result['processing_time']} ms")

client.on('complete', on_complete)

Event: error

Emitted when an error occurs.

def on_error(data):
    print(f"Conversion failed: {data['error']}")

client.on('error', on_error)

Supported Formats

The SDK supports conversion between all formats supported by Convertorio:

Common Formats:

• JPG/JPEG
• PNG
• WebP
• AVIF
• GIF
• BMP
• TIFF

Advanced Formats:

• HEIC/HEIF (iPhone photos)
• ICO (icons)
• SVG (vectors)
• RAW formats (CR2, NEF, DNG)
• PDF
• PSD (Photoshop)
• AI (Adobe Illustrator)
• EPS
• JXL (JPEG XL)

Advanced Conversion Options

The SDK supports advanced conversion options through the conversion_metadata parameter. This allows you to control aspect ratio, quality, resize dimensions, and more.

Aspect Ratio Control

Transform images to specific aspect ratios with automatic cropping or padding.

Available Aspect Ratios:

• original - Keep original aspect ratio (default)
• 1:1 - Square (Instagram, profile pictures)
• 4:3 - Traditional photos
• 16:9 - Widescreen, YouTube thumbnails
• 9:16 - Vertical video, Stories
• 21:9 - Ultrawide
• Custom ratios like 16:10, 3:2, etc.

Crop Strategies:

• fit - Add padding (letterbox/pillarbox) to maintain entire image
• crop-center - Crop from center (default)
• crop-top - Crop from top
• crop-bottom - Crop from bottom
• crop-left - Crop from left
• crop-right - Crop from right

Example:

result = client.convert_file(
    input_path='./photo.jpg',
    target_format='jpg',
    conversion_metadata={
        'aspect_ratio': '16:9',
        'crop_strategy': 'crop-center'
    }
)

Quality Control

Adjust compression quality for lossy formats (JPG, WebP, AVIF, HEIC).

Quality Range: 1-100

• 1 = Lowest quality, smallest file size
• 100 = Highest quality, largest file size
• Default: 85 (recommended balance)

Quality Guidelines:

• 95-100: Professional photography, archival
• 85-94: High quality for web (recommended)
• 70-84: Good quality, smaller files
• 50-69: Medium quality, significant compression
• 1-49: Low quality, maximum compression

Example:

result = client.convert_file(
    input_path='./photo.jpg',
    target_format='webp',
    conversion_metadata={
        'quality': 90
    }
)

ICO Format Options

Create Windows icons with specific pixel sizes.

Available Sizes: 16, 32, 48, 64, 128, 256

The image will be automatically cropped to square using the selected crop strategy.

Example:

result = client.convert_file(
    input_path='./logo.png',
    target_format='ico',
    conversion_metadata={
        'icon_size': 64,
        'crop_strategy': 'crop-center'
    }
)

Resize Control

Resize images to specific dimensions while optionally maintaining aspect ratio.

Parameters:

• resize_width - Target width in pixels (1-10000)
• resize_height - Target height in pixels (1-10000)

Resize Behavior:

• Width only: Height calculated automatically (maintains aspect ratio)
• Height only: Width calculated automatically (maintains aspect ratio)
• Both specified: Exact dimensions (may distort image if aspect ratio differs)

Example - Resize by width:

result = client.convert_file(
    input_path='./photo.jpg',
    target_format='jpg',
    conversion_metadata={
        'resize_width': 800  # Height will be calculated automatically
    }
)

Example - Resize by height:

result = client.convert_file(
    input_path='./photo.jpg',
    target_format='jpg',
    conversion_metadata={
        'resize_height': 600  # Width will be calculated automatically
    }
)

Example - Resize to exact dimensions:

result = client.convert_file(
    input_path='./photo.jpg',
    target_format='jpg',
    conversion_metadata={
        'resize_width': 1920,
        'resize_height': 1080  # May distort if original aspect ratio differs
    }
)

Example - Combine resize with aspect ratio:

# Create a 500x500 square thumbnail with center crop
result = client.convert_file(
    input_path='./photo.jpg',
    target_format='jpg',
    conversion_metadata={
        'aspect_ratio': '1:1',
        'crop_strategy': 'crop-center',
        'resize_width': 500,
        'quality': 90
    }
)

Resize Guidelines:

• Use width/height resize for responsive images
• Combine with aspect ratio for precise control
• Quality parameter affects lossy formats (JPG, WebP, AVIF)
• LANCZOS resampling ensures high-quality results

Examples

Basic Conversion

from convertorio_sdk import ConvertorioClient

client = ConvertorioClient(api_key='your_api_key_here')

result = client.convert_file(
    input_path='./input.png',
    target_format='jpg'
)

print(f"Done! {result['output_path']}")

With Progress Events

from convertorio_sdk import ConvertorioClient

client = ConvertorioClient(api_key='your_api_key_here')

def on_progress(data):
    print(f"[{data['step']}] {data['message']}")

def on_complete(result):
    print('✓ Conversion completed!')
    print(f"Output: {result['output_path']}")

client.on('progress', on_progress)
client.on('complete', on_complete)

result = client.convert_file(
    input_path='./photo.png',
    target_format='webp'
)

Batch Conversion

from pathlib import Path
from convertorio_sdk import ConvertorioClient

client = ConvertorioClient(api_key='your_api_key_here')

# Get all PNG files
images_dir = Path('./images')
png_files = list(images_dir.glob('*.png'))

# Convert all to WebP
for file_path in png_files:
    result = client.convert_file(
        input_path=str(file_path),
        target_format='webp'
    )
    print(f'Converted: {file_path}')

Advanced Conversion with Metadata

from convertorio_sdk import ConvertorioClient

client = ConvertorioClient(api_key='your_api_key_here')

# Convert to 16:9 aspect ratio with high quality
result = client.convert_file(
    input_path='./photo.jpg',
    target_format='webp',
    conversion_metadata={
        'aspect_ratio': '16:9',
        'crop_strategy': 'crop-center',
        'quality': 90
    }
)

print(f"Converted to 16:9: {result['output_path']}")

Error Handling

from convertorio_sdk import ConvertorioClient, ConversionError

client = ConvertorioClient(api_key='your_api_key_here')

try:
    result = client.convert_file(
        input_path='./image.png',
        target_format='jpg'
    )
    print(f"Success: {result['output_path']}")
except FileNotFoundError as e:
    print('Input file does not exist')
except ConversionError as e:
    print(f'Conversion failed: {e}')

    # Handle specific errors
    if 'Insufficient' in str(e):
        print('Not enough points/credits')

Rate Limiting

The API has the following rate limits:

• 1 request per second per IP address
• 5 concurrent jobs maximum per user

The SDK automatically handles rate limiting by polling job status with appropriate delays.

Error Handling

Common errors you might encounter:

Error	Description	Solution
ValueError: API key is required	No API key provided	Provide your API key in the constructor
FileNotFoundError	File doesn't exist	Check the file path
ConversionError: Invalid API key	Wrong or expired API key	Verify your API key in account settings
ConversionError: Insufficient credits	Not enough points	Purchase more points or use free tier
ConversionError: File size exceeds limit	File too large	Maximum file size is 20 MB
ConversionError: Conversion timeout	Job took too long	Try again or contact support

Best Practices

1. Reuse the client instance - Don't create a new client for each conversion
2. Use events for long conversions - Monitor progress instead of just waiting
3. Handle errors gracefully - Always wrap conversions in try/except
4. Respect rate limits - Use batch processing with delays if converting many files
5. Check file sizes - Maximum file size is 20 MB
6. Validate formats - Check that the target format is supported
