Why this tool is useful
Create a broadly editable lossless PNG copy of an AVIF asset while keeping private image bytes on the device.

Decode a browser-supported AVIF image and export a pixel-preserving PNG copy locally, without uploading the original or retaining its metadata.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
Create a broadly editable lossless PNG copy of an AVIF asset while keeping private image bytes on the device.
The browser's native image decoder reads the AVIF into a bounded canvas of at most 40 megapixels, then Canvas encodes fresh PNG pixels without copying EXIF metadata.
Choose an AVIF image, confirm its decoded dimensions and output size, then download the locally generated PNG copy.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
