Convert your JPG images to AVIF format with just a few clicks ✨
Converting your JPG images to AVIF format is quick and easy:
The conversion process transforms your images into the next-generation AVIF format, dramatically reducing file sizes while preserving or even enhancing visual quality, making your websites load faster and providing a better user experience.
AVIF emerged from an unexpected collaboration between tech rivals. The format was born from the Alliance for Open Media (AOM), founded in 2015 by companies that normally compete fiercely: Google, Mozilla, Microsoft, Amazon, Netflix, and others. What's remarkable is that these corporations set aside their differences to create a royalty-free image format that would benefit the entire web ecosystem. AVIF is actually derived from the keyframes of the AV1 video codec, meaning it leverages cutting-edge motion picture technology for still images. This heritage gives AVIF a unique advantage: it was designed from the ground up to handle the complexities of modern visual content, including HDR photography and wide color gamuts that didn't exist when JPG was created in 1992. Perhaps most surprising is AVIF's environmental impact—by reducing file sizes by up to 50% compared to JPG, widespread AVIF adoption could potentially save exabytes of data transfer annually, translating to significant energy savings and reduced carbon emissions from data centers and network infrastructure.
The JPG-to-AVIF conversion process represents a quantum leap in image encoding technology. While JPG uses the decades-old Discrete Cosine Transform (DCT) with fixed 8×8 pixel blocks, AVIF employs a sophisticated hierarchical approach with variable block sizes from 4×4 up to 128×128 pixels. This adaptive partitioning allows AVIF to precisely match its encoding strategy to image content—using larger blocks for smooth areas and smaller blocks for intricate details. AVIF also implements revolutionary intra-prediction techniques that can predict pixel values in up to 56 different directional patterns (compared to JPG's zero), dramatically reducing redundant information. What truly sets AVIF apart is its implementation of "global and local quantization," allowing it to vary compression levels within different regions of the same image—preserving critical details in focal areas while applying stronger compression elsewhere. AVIF also incorporates film grain synthesis, which can separate natural noise patterns from image content and reconstruct them after compression, maintaining a natural photographic look at drastically reduced file sizes. This technological sophistication explains why AVIF can achieve visually lossless quality at file sizes where JPG would show obvious degradation.
AVIF (AV1 Image File Format) is a modern image format that offers superior compression and quality compared to traditional formats. It uses the AV1 video codec to achieve smaller file sizes while maintaining excellent visual quality.
AVIF offers significantly better compression than JPG while maintaining higher image quality. Converting to AVIF can reduce file sizes by up to 50% compared to JPG, making your website faster and more efficient. AVIF also supports features like HDR and wide color gamut for better visual quality.
JPG (Joint Photographic Experts Group) is one of the most common image formats used for photos and web graphics. It uses lossy compression, which reduces file size by selectively discarding data. JPG is ideal for photographs and complex images with many colors, and is supported by virtually all devices, browsers, and applications.
Yes, you can upload JPG images up to 10MB in size. For larger files, we recommend compressing them first or using our image compression tool.
AVIF typically maintains better quality than JPG at the same file size. Our converter is optimized to preserve image quality while taking advantage of AVIF's superior compression capabilities.
Most conversions are completed within seconds. The exact time depends on the file size and the server load.
Yes, we take data security seriously. Your images are processed on our secure servers and are automatically deleted after conversion. We don't store your images permanently.
AVIF offers superior compression efficiency compared to JPG, PNG, and even WebP. It can reduce file sizes by up to 50% while maintaining better image quality. AVIF also supports features like HDR, wide color gamut, and alpha transparency. It's increasingly supported by modern browsers and platforms.
