FAQ
What filters are available and how do they work?
Six filters are available: Brightness and Contrast control light levels, Saturation adjusts color intensity, Grayscale converts to black-and-white, Sepia adds a warm vintage tone, and Blur softens the image. Each filter uses an independent slider from 0 to 200 percent, and effects stack so you can combine them freely.
Does the editor modify my original image file?
No. The editor reads your file into an in-memory canvas and applies filters as CSS-style transforms. Your original file remains untouched on disk. A new image is only generated when you explicitly download the result.
What file types and sizes does this tool handle?
It accepts PNG, JPEG, WebP, and most common image formats. Since processing is handled entirely by your browser's canvas engine, performance depends on your device — images up to around 4000×4000 pixels typically process smoothly on modern hardware.
