Compress Image
Reduce image size without making things complicated. Choose how strongly you want ConvertWin to compress your image.
Your files stay on your device.
Which level?
Light — when image quality matters most.
Balanced — the best choice for most images.
Strong — when a smaller file matters more.
Maximum — when size matters much more than fidelity.
Are my images uploaded?
No. Compression runs locally inside your browser. ConvertWin does not store your image, filename or metadata.
Does compression resize my image?
No. Version 2 preserves the original pixel dimensions. Resizing will remain a separate future tool.
