Add AVIF images
Drop static AVIF files onto the upload card, click anywhere in it to browse, or paste an AVIF image from your clipboard.
IMAGE CONVERTER
Turn static AVIF images into widely compatible JPG files without sending the images to a conversion server. Batch files, control JPEG quality, and choose how transparency is filled.
Higher quality keeps more detail but usually produces a larger JPG.
JPG has no alpha channel. Transparent AVIF pixels are flattened onto this color.

HOW TO USE
Drop static AVIF files onto the upload card, click anywhere in it to browse, or paste an AVIF image from your clipboard.
Set JPEG quality and select the solid color that should replace any transparent or semi-transparent pixels.
Convert locally, review each preview and real file size, then download individual JPGs or the full batch as a ZIP.
Key Features
Queue up to 30 static AVIF images and convert them together instead of repeating the same workflow file by file.
Choose quality from 40% to 100% and reconvert whenever you need a different balance between detail and bytes.
Pick the exact solid background color used when transparent AVIF pixels must become opaque JPG pixels.
Decode, composite and encode on your device so private screenshots and images do not need a conversion upload.
See actual AVIF input bytes and encoded JPG bytes instead of assuming that converting formats always makes a file smaller.
Download finished files individually or package all successful JPG results into one ZIP built locally in the browser.
FORMAT GUIDANCE
AVIF is excellent for efficient web delivery, but JPG is still a useful compatibility format for older software, strict upload forms, office workflows and recipients who expect a conventional photo file. Conversion decodes the AVIF and then creates a new JPEG, so it is a compatibility step rather than a quality upgrade.
JPEG is lossy and cannot preserve transparency. Keep the original AVIF as your master when possible, choose a suitable quality for the JPG copy, and use the background control when the source has transparent edges. If your real goal is simply to reduce bytes without changing format, Motricialy's Image Compressor is the more direct workflow.
The converter keeps the original pixel dimensions and strips metadata during browser canvas re-encoding. It depends on the browser's built-in AVIF decoder, so an up-to-date browser is required. Animated AVIF files are intentionally rejected rather than silently flattened to one frame.
FAQ
Usually yes to some degree. JPG uses lossy compression, so the conversion creates a new JPEG encoding. A higher quality setting preserves more visual detail but often produces a larger file.
No. AVIF is often more compression-efficient than JPEG, so the JPG can be larger. This tool shows the real encoded size instead of promising a reduction that may not happen.
JPG cannot store transparency. Transparent and semi-transparent pixels are composited onto the background color you choose before the JPG is encoded.
No. V1 rejects animated AVIF files so an animation is never silently replaced by a single still image. Use a dedicated animation workflow when motion must be preserved.
No conversion upload is required. The browser reads the selected files, decodes them and creates the JPG results locally on your device.
No. Browser canvas re-encoding creates a new pixel-based output and normally strips EXIF, GPS and other source metadata. If you need to inspect the original first, use the Image Metadata Viewer.
