Simple effects turn an ordinary shot into a stylized picture. Just choose an effect, set its strength with the slider and see the result in the preview window at once. You can process one photo or a whole series of files.

The black and white conversion removes color and leaves the play of light and shadow. Negative inverts the colors, as on film. Posterize reduces the number of shades and gives a poster look, while blur softens the picture or hides unwanted details.

Pixelation builds the image from large square blocks. It is used to cover a license plate, a face or text, as well as to imitate old games. The higher the value, the larger the blocks, so details disappear completely.

The pencil drawing effect is based on outlines: smooth areas stay light, while the boundaries of objects are emphasized with dark strokes. Sharpening boosts fine details, and a vignette darkens the edges of the frame and draws attention to the center.

The result can be saved in the original format, as JPG, PNG or WebP. Transparent areas are preserved where the format allows it. Everything happens in the browser, files do not go to a server, and the pixel size does not change.
