Frequently Asked Questions
Is my image data sent to a server?
No. Compression uses Canvas API encoding in your browser. Image data is not transmitted to any server.
How much can file size be reduced?
It depends on the original image content and compression settings, but typically 50-80% size reduction is possible. JPEG/WebP formats work best for photos and gradients, while PNG is optimal for illustrations and logos.
Can transparent images be compressed?
Yes, PNG and WebP formats support transparency (alpha channel). However, if you convert to JPEG format, transparent areas will be replaced with white.
What quality setting should I use for web images?
For most website images, a quality of 75-85% provides a good balance of visual quality and file size. For e-commerce product photos, try 80-90%. Check the preview to confirm quality before downloading.
What image formats are supported?
Input supports JPEG, PNG, and WebP formats. Output formats are the same, and you can either keep the original format or convert to a different one.
