Image Filters and Effects
Adjust an image with live filters: brightness, contrast, and saturation sliders, plus one-click grayscale, sepia, and color invert. The preview updates instantly as you drag, and the download is rendered at full resolution. Everything runs in your browser, so the image never leaves your device.
How to apply filters to an image
- Drop an image in, or click to browse.
- Drag the brightness, contrast, and saturation sliders, or toggle grayscale, sepia, or invert.
- Pick an output format and download the result.
Examples
Convert a photo to black and white
A color photo with grayscale on and contrast +20
A crisp black-and-white version at full resolution
Frequently asked questions
Is my image uploaded anywhere?
No. All filtering runs in your browser on the raw pixels. The image never leaves your device, so private photos stay private.
Does the preview match the download?
Yes. The preview uses the exact same pixel math as the export, just on a smaller copy for speed. The downloaded file is processed at full resolution.
How is grayscale calculated?
Each pixel is converted using Rec. 601 luma (about 30% red, 59% green, 11% blue), which matches how we perceive brightness, rather than a flat average.
Can I stack filters?
Yes. Brightness, contrast, and saturation apply in that order, then grayscale, sepia, and invert. Combine them to build a custom look.
Will it change the file type?
Only if you choose to. You can export as PNG (lossless), JPEG, or WebP regardless of the input format.
