Frequently asked questions

What effects are available?

Grayscale, sepia, invert, blur, and sharpen are the main effects. These cover the most common image adjustment needs for web and design use.

Can I combine multiple effects?

Apply effects one at a time. For combining multiple effects, download after the first, re-upload, and apply the second.

Will effects permanently change my original?

No. Your uploaded file is untouched. Only the downloaded result has the effect applied.

How much blur can I apply?

The blur slider ranges from subtle softening to heavy blur. Useful for creating background blur effects or obscuring sensitive information in screenshots.

Is the sharpen filter good for fixing blurry photos?

Sharpen enhances existing edges but cannot recover detail from a genuinely blurry or out-of-focus photo. It works well to make a slightly soft image crisper, not to rescue heavily blurred photos.

What formats does the effects tool support?

JPG, PNG and WebP inputs all work. The output format matches the input.
