With the rise of high-resolution displays and advanced image compression technologies, there’s been a growing demand for image formats that offer both superior quality and smaller file sizes. One such format is AVIF, which stands for AV1 Image File Format. Developed by the Alliance for Open Media, AVIF is a next-generation image format that uses advanced compression algorithms to deliver images that are both visually stunning and highly efficient.
However, despite its many advantages, AVIF is not yet widely supported by all devices and platforms, which means that it may not be the best choice for all users. In some cases, it may be necessary to convert AVIF files to a more widely recognized format such as JPG (or JPEG), which is one of the most popular image formats in use today.
If you need to convert AVIF files to JPG but don’t want to rely on online conversion tools, then you’ve come to the right place. In this article, we’ll show you how to convert AVIF to JPG offline using various tools, as well as provide some tips to ensure a successful conversion.
What is AVIF?
AVIF is a next-generation image format that uses advanced compression techniques to deliver high-quality images with smaller file sizes than traditional image formats. It is based on the AV1 video codec, which was developed by the Alliance for Open Media (AOM). The AOM is a group of major technology companies, including Google, Microsoft, Apple, and Amazon, that collaborates to develop open, royalty-free media formats and codecs.
AVIF offers several advantages over other image formats, including JPEG, PNG, and WebP. One of the main benefits is its superior compression efficiency, which means that it can deliver images with better quality and smaller file sizes. This is achieved through the use of advanced encoding techniques such as intra-frame coding, inter-frame coding, and tiling.
In addition to its compression efficiency, AVIF also supports a wide range of advanced features, including alpha channel transparency, wide color gamut, and high dynamic range (HDR). These features make it an ideal format for high-quality images, especially those that need to be displayed on high-resolution displays or in environments with challenging lighting conditions.
Despite its many advantages, AVIF is not yet widely supported by all devices and platforms. This means that some users may need to convert AVIF files to other formats, such as JPG, in order to ensure compatibility with all devices.
What is JPG / JPEG?
JPEG (short for Joint Photographic Experts Group) is one of the most popular image formats in use today. It was first introduced in 1992 and has since become a widely recognized standard for compressing digital images.
JPEG uses a lossy compression algorithm, which means that some data is discarded in order to reduce the file size. This can result in a loss of image quality, especially if the compression is too high. However, JPEG allows users to control the compression level and balance the tradeoff between image quality and file size.
One of the main advantages of JPEG is its wide compatibility with different devices and platforms. Almost all modern devices, including smartphones, tablets, laptops, and desktop computers, can display JPEG images without any additional software or plugins.
JPEG is also well-suited for storing photographic images and other complex images with lots of detail and color variations. This is because the format supports a wide range of color depths and can display millions of colors.
Despite its many advantages, JPEG does have some limitations. For example, it is not ideal for images that require transparency or animation, and it can struggle to retain detail in areas with sharp contrasts. However, for most general-purpose image applications, JPEG remains a reliable and widely supported format.
Why convert AVIF to JPG / JPEG offline?
There are several reasons why you might want to convert AVIF to JPG offline, rather than using online conversion tools. Here are a few:
- No Internet connection required: When you convert files online, you need to have a stable internet connection in order to upload and download the files. If your internet connection is slow or unreliable, this can be a frustrating and time-consuming process. By converting AVIF to JPG offline, you can avoid these issues and complete the conversion more quickly.
- Privacy and security: Online conversion tools often require you to upload your files to their servers, which can raise privacy and security concerns. When you convert files offline, you can be sure that your files are not being shared or accessed by third parties.
- Customization and control: Many online conversion tools offer limited customization options, such as the ability to adjust the image quality or compression level. By converting AVIF to JPG offline, you can use specialized tools that offer more advanced customization options and greater control over the conversion process.
- Compatibility with offline devices: If you need to use your converted images on a device that does not have an internet connection, it may be more convenient to convert them offline in the first place. This can save you time and hassle in the long run.
Overall, converting AVIF to JPG offline can be a convenient and efficient way to ensure compatibility and flexibility for your image files.
Offline AVIF to JPG conversion tools
If you’re looking to convert AVIF to JPG offline, one of the best tools to use is the Python Imaging Library, or Pillow for short. Pillow is a popular open-source library for working with images in Python and offers a range of functions for converting, resizing, and manipulating image files.
To use Pillow for AVIF to JPG conversion, you will need to install the library first. This can be done using pip, the package installer for Python. Here’s how to install Pillow:
pip install PillowOnce you have installed Pillow, you can use it to convert your AVIF files to JPG. Here’s an example Python script that converts all the AVIF files in a directory to JPG:
from PIL import Image
import os
input_dir = 'path/to/avif/files'
output_dir = 'path/to/output/files'
for filename in os.listdir(input_dir):
if filename.endswith('.avif'):
# Open the AVIF file
with Image.open(os.path.join(input_dir, filename)) as im:
# Convert the image to RGB
rgb_im = im.convert('RGB')
# Save the converted image as a JPEG file
output_filename = os.path.splitext(filename)[0] + '.jpg'
rgb_im.save(os.path.join(output_dir, output_filename))In this script, the AVIF files are first opened using the Image.open() function, which creates a Pillow Image object. The convert() function is then used to convert the AVIF image to the RGB color space, which is required for JPEG files. Finally, the converted image is saved as a JPEG file using the save() function.
How to convert AVIF to JPG offline using ToolHub’s AVIF to JPEG converter
