# Image Filter Effects

> Apply grayscale, sepia, blur, brightness, contrast and invert effects to images.

To apply a filter, add your images, pick an effect and adjust the intensity slider. Effects use the browser's native canvas filter pipeline, which is hardware accelerated, so even large photographs process almost instantly and never leave your device.

## FAQ

### Do filters reduce image quality?

They alter pixel values irreversibly, so applying and reverting does not restore the original. Work from a copy, and prefer a single pass over stacking filters, since each re-encode of a lossy format compounds the loss.
