imghdr 1.0.0 (Python 3.13+)

Backport of the Python standard library imghdr module for Python 3.13 and later.

The imghdr module was removed in Python 3.13 (PEP 594). This package provides the same API so existing code and dependencies (e.g. IO-Paint / IOPaint) can run on Python 3.13 without changes.

Installation

From this Hugging Face repo

pip install https://huggingface.co/ussoewwin/imghdr-1.0.0-py3-none-any/resolve/main/imghdr-1.0.0-py3-none-any.whl

Or clone the repo and install the wheel:

pip install imghdr-1.0.0-py3-none-any.whl

Requirements

• Python >= 3.13

The wheel is py3-none-any (pure Python, no platform-specific code), so it works on Windows, Linux, and macOS.

Usage

Same as the former standard library:

import imghdr

# From file path
fmt = imghdr.what("image.png")   # -> "png"

# From file-like object
with open("photo.jpg", "rb") as f:
    fmt = imghdr.what(f)         # -> "jpeg"

# From bytes
fmt = imghdr.what(None, h=header_bytes)
