Six sliders (brightness, contrast, grayscale, saturation, sepia, and blur) combine into a single filter applied uniformly across the whole image, previewed live and then baked into a PNG on export. Nothing here selects or masks a region. Every adjustment hits the entire frame at once.

When you'd use this

Converting a color photo to grayscale or sepia for a vintage look, correcting a flat or washed-out scan by pushing brightness and contrast, or softening a background image with blur before laying text over it.

Common errors

Setting grayscale to 100% doesn't make the sepia slider a no-op. The filters apply in sequence, so a sepia tint added after grayscale still colors the image instead of leaving it neutral gray. Leave sepia at 0 if you want pure grayscale.

These adjustments apply to the entire image with no way to target just a face or a corner. To obscure or alter one region only, use Photo Censor, which handles localized blur or pixelation on a dragged selection.

Frequently asked questions

Do the slider adjustments change the file, or just the on-screen preview?

They only affect the preview until you export. Downloading renders the current combination of filter values onto a new canvas at the image's original resolution and saves that as a PNG.

Can I apply a filter to just part of the photo?

Not here. Every slider affects the whole image uniformly. For adjustments limited to a specific region, use Photo Censor's drag-to-select blur or pixelation instead.

What file format does the download use?

Always PNG, whatever format the original upload happened to be in.
