Installation

pip install convalt

For audio conversion support, you also need FFmpeg installed on your system:

Windows: Download from ffmpeg.org

macOS:

brew install ffmpeg

Linux:

sudo apt-get install ffmpeg

Quick Start

from Convalt import Convalt

converter = Convalt()

# Convert image formats
converter.convert("input.png", "output.jpg", quality=90)

# Convert audio formats
converter.convert("song.mp3", "song.wav", bitrate="320k")

# Batch convert multiple files
files = ["image1.png", "image2.png", "image3.png"]
converter.batch_convert(files, "jpg", output_dir="converted")

Usage Examples

Basic Image Conversion

from Convalt import Convalt

converter = Convalt()

# PNG to JPEG
converter.convert("photo.png", "photo.jpg", quality=95)

# JPEG to PNG
converter.convert("image.jpg", "image.png")

# PNG to GIF
converter.convert("animation.png", "animation.gif")

Basic Audio Conversion

# MP3 to WAV
converter.convert("song.mp3", "song.wav", bitrate="320k")

# WAV to MP3
converter.convert("audio.wav", "audio.mp3", bitrate="192k")

# MP3 to OGG
converter.convert("music.mp3", "music.ogg")

Batch Conversion

# Convert multiple images
image_files = ["photo1.png", "photo2.png", "photo3.png"]
converter.batch_convert(
    image_files, 
    "jpg", 
    output_dir="converted",
    quality=85
)

# Convert multiple audio files
audio_files = ["track1.mp3", "track2.mp3"]
converter.batch_convert(
    audio_files,
    "wav",
    output_dir="converted_audio"
)

Advanced Options

# High-quality JPEG with optimization
converter.convert(
    "original.png",
    "output.jpg",
    quality=98,
    optimize=True
)

# Optimized PNG
converter.convert(
    "large.png",
    "optimized.png",
    optimize=True
)

# High-bitrate audio
converter.convert(
    "source.wav",
    "output.mp3",
    bitrate="320k"
)

Error Handling

from Convalt import (
    Convalt, 
    ConversionError, 
    UnsupportedFormatError
)

converter = Convalt()

try:
    converter.convert("input.png", "output.jpg")
except FileNotFoundError:
    print("Input file not found")
except UnsupportedFormatError:
    print("Format conversion not supported")
except ConversionError as e:
    print(f"Conversion failed: {e}")

Check Supported Formats

converter = Convalt()
formats = converter.get_supported_formats()

print("Image formats:", formats['image'])
print("Audio formats:", formats['audio'])

Conversion History

converter = Convalt()

# Perform conversions
converter.convert("image1.png", "image1.jpg")
converter.convert("image2.png", "image2.jpg")

# View history
history = converter.get_history()
for item in history:
    print(f"{item['input_format']} → {item['output_format']}")

API Reference

Convalt

convert(input_path, output_path, **kwargs)

Convert a file from one format to another.

Parameters:

• input_path (str): Path to the input file
• output_path (str): Path to the output file
• quality (int): JPEG/WEBP quality, 1-100 (default: 95)
• optimize (bool): Optimize output file size (default: True)
• bitrate (str): Audio bitrate, e.g. "192k", "320k" (default: "192k")

Returns: Path to the converted file (str)

Raises:

• FileNotFoundError: Input file doesn't exist
• UnsupportedFormatError: Format conversion not supported
• ConversionError: Conversion failed

batch_convert(input_files, output_format, output_dir=None, **kwargs)

Convert multiple files to the same output format.

Parameters:

• input_files (list): List of input file paths
• output_format (str): Target format without dot (e.g., 'png', 'mp3')
• output_dir (str, optional): Output directory
• **kwargs: Additional conversion options

Returns: List of output file paths

get_supported_formats()

Get all supported formats by category.

Returns: Dictionary with 'image' and 'audio' keys containing lists of supported formats
