Why convert AVIF to JPG?
AVIF (AV1 Image File Format) is the newest image standard, delivering 50 % smaller files than JPEG at equivalent quality by leveraging the AV1 video codec for still images. Chrome, Firefox, and modern Android ship AVIF support natively. The problem: Windows Photo Viewer, most legacy graphics software, email clients, and content management systems still do not handle AVIF — they either display a broken icon or refuse the upload.
Converting AVIF to JPG gives you a file that opens everywhere: Windows Photos, Paint, Photoshop CS, IrfanView, Lightroom Classic, every email client, and every web platform''s upload form. JPEG''s universal compatibility comes at the cost of somewhat larger file sizes, but that trade-off is worth it when you need the image to just work.
Common sources of AVIF images include web scraping, downloaded assets from modern CDNs, exported images from Chrome DevTools, and stock photo sites that now default to AVIF delivery. Designers working from reference libraries frequently encounter AVIF files that their tools cannot ingest.
File Converter Pro decodes AVIF and writes JPG entirely offline on Windows 10 and 11. No upload required, no browser tricks, no format-conversion web service needed.
How to convert AVIF to JPG on Windows
- Install File Converter Pro. Download File Converter Pro from the Microsoft Store. The free trial supports full-resolution AVIF to JPG conversion.
- Add AVIF files to the queue. Drag AVIF files into the app — single files or a folder. AVIF files from any source are accepted, including downloaded web assets and exported browser captures.
- Select JPG and quality. Choose JPG as output. Set quality 85-90 for general use. The app shows an estimated output file size before you start.
- Convert locally. Click Convert. AVIF decoding and JPG encoding run on your CPU with no upload. Output JPGs are saved to your specified folder.
Batch conversion for big folders
Designers and developers who work with modern web assets often download or generate batches of AVIF images that need to be converted for use in legacy tools or client deliverables. File Converter Pro handles these batches efficiently.
- Process dozens or hundreds of AVIF files in a single queue run.
- Mixed AVIF and other formats in the same folder are handled without errors.
- Output JPGs keep the original filenames with the extension swapped.
- No internet connection needed — works in air-gapped environments.
Quality settings that actually matter
When converting AVIF (a lossy format) to JPG (also lossy), you are re-compressing already-compressed image data. Setting JPG quality too low doubles the compression artefacts. Recommended settings:
- Quality 90: near-transparent loss, recommended for photos and design assets.
- Quality 85: excellent balance for general use — typically half the original AVIF file size.
- Quality 75: compact web thumbnails. Visible artefacts on close inspection but fine at normal zoom.
- Colour space: AVIF supports wide-gamut and HDR. File Converter Pro converts to sRGB for JPG output, ensuring correct colours in all viewers.
Common issues and fixes
- Output JPG looks different from AVIF in browser. Browsers display AVIF in wide-gamut or HDR mode if supported. The JPG output uses sRGB — colours may look slightly less vivid but will be accurate and consistent across all apps.
- AVIF file not recognised. Some AVIF files use an older file-type box or a different MIME subtype. File Converter Pro handles most AVIF variants including .avif and .avifs sequences.
- Transparency in AVIF not carried over. AVIF supports alpha channels; JPG does not. Transparent areas are composited on white by default. Switch to PNG output if you need to preserve transparency.
- Conversion slower than expected. AVIF decoding is CPU-intensive due to AV1 complexity. A modern 4-core CPU decodes roughly 10-20 AVIF images per second at 4K resolution.

FAQ
What is AVIF and why can my software not open it?
AVIF (AV1 Image File Format) is a next-generation image format built on the AV1 video codec. It launched in 2019 and is supported by modern browsers but not yet by most desktop software, Windows Explorer thumbnails, or legacy graphics apps. Converting to JPG gives you a file that opens everywhere.
Does converting AVIF to JPG degrade quality significantly?
At quality 85-90 the degradation is minimal and invisible at normal viewing sizes. Because AVIF is already lossy, you are re-compressing — keep quality at 85 or above to avoid stacking artefacts.
Can I convert AVIF files in bulk?
Yes. Drag a folder of AVIF files into File Converter Pro and all of them are added to the batch queue. There is no per-file limit on count or size.
Does converting AVIF to JPG preserve transparency?
No — JPG does not support transparency. Transparent areas are filled with white (or a colour you choose). If you need transparency preserved, convert to PNG instead.
