heiya 1.2.2

Convert between image and High Efficiency Image (HEIC/AVIF) with ease.

Heiya

A one-line solution for photographers to simply convert JPEG into HEI(High Efficiency Image) with HEIC/AVIF and preserve all the metadata.

Introduction

Heiya allows you to easily translate between JPG/TIFF and HEIC/AVIF, without losing image metadata such as geotag and lens information. All the common operations can be done using one line of code.

It is developed for photographers with a storage budget (like myself, lol) to build an automatic and efficient image storage pipeline.

JPEG was invented six years before my existence. I'm now 24, graduating from my double Master's degree next summer.

And yet, the majority of cameras in the current age still shoot JPEG.

HEIC and AVIF are what are called "High-Efficiency Images" (You can read about them here: AVIF vs HEIC).

• These are the future of media formats, JPEG is getting deprecated.
• They can result in a file size of as much as 100x less than traditional JPEGs.
• Devices and operating systems now have good support for both formats.
• However, there are no free and easy-to-use tools out there to simply encode all the JPEGs my camera took into AVIFs while preserving metadata.

Install Heiya from PyPI

Heiya is developed and tested on macOS and hasn't been tested on Linux, it doesn't support Windows for now.

pip install heiya

Examples

A complete set of heiya examples can be found in the Heiya Demo Notebook.

To-Do & Help Needed

• Seek alternative for pyheif (Which is why Heiya does not support Windows).
• Attempt an implementation using imagemagick to enable bitrate higher than the current 8 bit.

What does the name mean?

• HEI - High Efficiency Image.
• Ya - In Chinese, 压(yā) means "to compress".

But mostly just a reference to uncle Roger's "Heiya" when he saw the BBC host rinse and drain cooked rice with tap water (smh... here's the video).
