easyconvio

Simple file conversion and transformation for Python. Read a file, transform it, export to another format. That's it.

No complex pipelines, no bloated abstractions — just a clean, fluent API to convert and manipulate files across images, audio, video, documents, and more.

Usage

Images

import easyconvio as ec

img = ec.read_jpg("photo.jpg")
print(img)       # <ImageFile 'photo.jpg' (jpg)>
print(img.size)  # (1920, 1080)
print(img.mode)  # RGB

# Geometric transforms
img = img.resize(800, 600)
img = img.crop(0, 0, 400, 300)
img = img.rotate(90)
img = img.flip_horizontal()
img = img.thumbnail(200, 200)

# Color adjustments
img = ec.read_jpg("photo.jpg")
img = img.brightness(1.2)
img = img.contrast(1.5)
img = img.sharpness(2.0)
img = img.saturation(0.8)
img = img.grayscale()
img = img.sepia()
img = img.invert()
img = img.auto_contrast()
img = img.equalize()
img = img.opacity(0.5)

# Filters and compositing
img = ec.read_jpg("photo.jpg")
img = img.blur(radius=3)
img = img.add_border(10, color="red")
img = img.paste("overlay.png", 50, 50)

# Convert
img.to_png("photo.png")
img.to_webp("photo.webp", quality=80)
img.to("gif", "photo.gif")  # generic .to() also works

Audio

audio = ec.read_mp3("song.mp3")
print(audio.duration)     # 180.5 (seconds)
print(audio.channels)     # 2
print(audio.sample_rate)  # 44100

# Editing
audio = audio.trim(start=10, end=60)
audio = audio.append("outro.mp3")
audio = audio.overlay("effect.wav", position=5)
audio = audio.repeat(2)
audio = audio.reverse()
audio = audio.silence(3)

# Effects
audio = ec.read_mp3("song.mp3")
audio = audio.volume(6)
audio = audio.normalize()
audio = audio.fade_in(2)
audio = audio.fade_out(3)
audio = audio.low_pass_filter(3000)
audio = audio.high_pass_filter(200)
audio = audio.speed(1.5)

# Format settings
audio = audio.set_channels(1)  # mono
audio = audio.set_frame_rate(22050)

# Convert
audio.to_wav("song.wav")
audio.to_flac("song.flac")
audio.to("ogg", "song.ogg")

Video

video = ec.read_mp4("clip.mp4")
print(video.duration)  # 120.0 (seconds)
print(video.size)      # (1920, 1080)
print(video.fps)       # 30.0

# Editing
video = video.clip(0, 30)
video = video.resize(1280, 720)
video = video.crop(0, 0, 640, 360)
video = video.concatenate("clip2.mp4")
video = video.loop(3)

# Speed and time
video = ec.read_mp4("clip.mp4")
video = video.speed(2.0)
video = video.reverse()
video = video.set_fps(24)

# Visual effects
video = ec.read_mp4("clip.mp4")
video = video.rotate(90)
video = video.flip_horizontal()
video = video.grayscale()
video = video.brightness(1.3)
video = video.fade_in(2)
video = video.fade_out(2)

# Audio
video = ec.read_mp4("clip.mp4")
video = video.mute()
video = video.add_audio("music.mp3")
video = video.volume(0.5)

# Extract
video = ec.read_mp4("clip.mp4")
video.extract_audio("clip_audio.mp3")
video.snapshot(5.0, "frame_5s.png")

RAR can be read and extracted, but cannot be written (no Python writer exists). Conversions from RAR target other archive formats. Proprietary formats (AI, CDR) and dead ebook formats (LRF, PDB, SNB) are intentionally not supported.
