❓ Frequently Asked Questions
What image formats are supported? ▾
The compressor works with JPG, PNG, WebP and most common image formats. Output is saved as JPEG for maximum compression. For transparent images, PNG output preserves transparency.
How much compression is applied? ▾
The tool uses a quality setting of 70% which provides a good balance between file size and visual quality. Images are also resized if they exceed 2048px in any dimension.
Is my image uploaded to any server? ▾
No — image compression runs entirely in your browser using the Canvas API. Your image files are never uploaded, transmitted or stored anywhere. 100% private.
