Questions about this tool
No. The selected image is decoded and encoded inside your browser tab. Its contents and filename are not uploaded for processing.
The AVIF encoder is lossy by default. Use the quality slider to balance visual quality and file size.
Different formats suit different image content. A higher quality setting, transparency, photographic noise, or converting a compact source to PNG can produce a larger result.
This free browser tool converts one image at a time. GetCompress provides batch conversion, reusable presets, more formats, and additional codec controls on the desktop.
