About JPG Format
Everything you need to know about the JPG format and why we convert AVIF to JPG
What is JPG/JPEG Format?
JPG (or JPEG, which stands for Joint Photographic Experts Group) is one of the most widely used image formats in the world. It was officially standardized in 1992 and has since become the default format for photographic images on the web and in digital cameras.
JPG is a lossy compression format, meaning it reduces file size by permanently discarding certain information from the image. This makes it particularly suitable for photographs and complex graphics where the slight loss in quality is often imperceptible to the human eye, while the reduction in file size is substantial.
Key features of JPG format:
- Lossy compression: Reduces file size by discarding some image data
- Variable compression: Quality level can be adjusted to balance file size and image quality
- Color support: Up to 16.7 million colors (24-bit)
- Wide compatibility: Supported by virtually all devices, browsers, and applications
- Fast loading: Optimized for quick loading on websites
- Progressive rendering: Can be configured to display progressively as it loads

JPG Format History and Development
The JPEG standard was developed by the Joint Photographic Experts Group (hence the name) and was first published in 1992. It was designed specifically to address the need for an efficient way to store and transmit photographic images in a digital format.
Before JPEG, digital images were often stored uncompressed or with simple lossless compression techniques, resulting in very large file sizes. The introduction of JPEG revolutionized digital imaging by making it possible to store high-quality photographs in reasonably sized files, which was especially important in the early days of the internet when bandwidth was severely limited.
Timeline of JPG development:
- 1986: Joint Photographic Experts Group formed
- 1992: JPEG standard officially published (ISO/IEC 10918-1)
- 1994: JPEG becomes widely adopted on the early World Wide Web
- 2000: JPEG 2000 introduced (using wavelet compression)
- 2009: JPEG XR introduced (Microsoft development)
- Present: Original JPEG remains the most widely used format despite newer alternatives
JPG vs. Other Image Formats
While JPG is the most widely used image format, it has both advantages and limitations compared to other formats:
| Feature | JPG | PNG | WebP | AVIF |
|---|---|---|---|---|
| Compression type | Lossy | Lossless | Both | Lossy |
| Transparency | No | Yes | Yes | Yes |
| Best for | Photos | Graphics | Web images | Modern web |
| Compatibility | Universal | Universal | Good | Limited |
| File size (photos) | Medium | Large | Small | Smallest |
While newer formats like AVIF offer better compression and additional features, JPG's universal compatibility makes it the most practical choice in many situations, which is why our AVIF to JPG converter free service is so valuable.
Why Convert AVIF to JPG?
Despite AVIF's technical advantages, there are many practical reasons to convert AVIF images to JPG format:
Universal Compatibility
JPG is supported everywhere, including older devices, software, and platforms that don't recognize AVIF files.
Social Media Sharing
Most social media platforms automatically convert uploads to JPG anyway, so starting with JPG ensures you maintain control over the conversion quality.
Email Attachments
JPG files are universally supported as email attachments, while AVIF files might not be viewable by all recipients.
Software Editing
Most image editing software fully supports JPG, while AVIF support remains limited in many popular editing applications.
JPG Quality Settings
When converting AVIF to JPG using our converter, you can adjust the quality setting, which controls the balance between file size and image quality:
Low Quality (10-50)
Smallest file size, visible compression artifacts
Best for: Thumbnails, previews
Medium Quality (60-80)
Good balance between file size and quality
Best for: Web images, general use
High Quality (85-100)
Excellent quality, larger file size
Best for: Photography, printing
Our AVIF to JPG converter free tool defaultly uses a quality setting of 80, which provides an excellent balance between image quality and file size for most purposes. You can adjust this setting based on your specific needs.
