How to use this tool
Choose one AVIF file. Set maximum dimensions and, for JPEG/WebP/AVIF, quality. Select a flattening color for opaque output, convert, then inspect and download.
Accuracy and scope
GIF uses a palette of at most 256 colors. Fine gradients can lose detail. This converter creates a single still frame, not an animation. Maximum input 50 MiB and 16 megapixels. Resize preserves aspect ratio and never enlarges. Animation/multipage input is rejected. Orientation is applied; metadata is not copied. High bit depth and source color profiles are not preserved. The output is generated by the server and expires after 15 minutes.
