Filters & Effects
Pick a preset or tune the sliders and add a special effect. For GIFs the same effect is applied to every frame.
Filters use the browser canvas filter feature (older Safari may not apply some of them).
For GIFs, the same effect is applied to every frame and saved as a GIF.
How to use
- Upload an image or GIF.
- Pick a preset or adjust sliders and special effects.
- Check the preview and download.

What this tool does
Applies brightness, contrast, saturation, hue, grayscale, sepia, invert and blur to an image or GIF, and adds special effects such as sharpen, vignette, posterize, pixel art and halftone. There are also presets such as vintage and lomo.
Steps
- Upload an image or GIF.
- Press a preset (Original, Vintage, Lomo, Warm, Cool, B&W, Dramatic, Fade) or adjust the sliders and checkboxes yourself.
- If needed choose a "Special effect" and set its amount with the strength slider that appears.
- Fine-tune while watching the preview, and press "Reset effects" if you do not like it.
- Choose the format and quality and press "Download".
Settings
- Brightness, contrast, saturation (0-200%, saturation 0-300%): 100 is the original.
- Hue (-180 to 180 degrees): rotates the color wheel to shift all colors.
- Blur (0-20): blurs the image. 0 means none.
- Grayscale, Sepia, Invert: applied when checked.
- Sharpen makes edges crisper. Vignette darkens the edges. Posterize reduces color levels for a simpler look. Pixel art makes big dots and reduces color levels. Halftone is a black and white image with larger black dots where it is darker, on a white background.
How it works
Brightness, contrast, saturation, hue, black & white, sepia, invert and blur are applied in one go with the browser canvas filter feature. The special effect is calculated on top. Sharpen uses a 3x3 kernel that boosts the center pixel and subtracts the pixels directly above, below, left and right to emphasize edges, vignette overlays a circular gradient that darkens toward the edges, and posterize reduces each channel to 2-16 levels. Pixel art shrinks the image to the block size and enlarges it without smoothing, and halftone takes the average brightness of each cell and draws a larger dot where it is darker. The preview is calculated on a reduced copy and the same settings are applied again at the original resolution when you save.
Good to know
- The color filters use the browser's canvas filter feature, so some older browsers (older Safari) may not apply them.
- Halftone produces black and white dots, so color information is lost.
- A GIF gets the same effects on every frame and is saved as a GIF. Large files or many frames take time.
- Your work is gone when you close the tab.
