Upload your photo, choose the B&W preset, and download the grayscale result. If the conversion looks flat, raise the contrast slider slightly to deepen shadows and brighten highlights. Lowering saturation to zero achieves a similar monochrome look while keeping the other sliders available for fine tuning.
Select the Sepia preset for warm brown vintage tones, then adjust saturation and brightness until the mood feels right. Slightly reduced contrast often makes sepia portraits look softer and more authentic. The filter and all three sliders apply together, so small changes combine into a personal style.
Filters shift tones, so an image that started dark can lose detail in the shadows. Raise the brightness slider above 100 to lift the whole image, then use contrast to restore depth. The value 100 always means neutral for brightness, contrast and saturation, which makes experimenting easy to undo.
Invert swaps every color for its opposite, turning a photo into a negative-style image. It is useful for checking film negatives, creating high-contrast graphics and spotting details that are hard to see normally. Combined with grayscale, invert produces a classic X-ray style effect for creative projects.
Yes. The preset and the brightness, contrast and saturation sliders all apply together in one edit, so you can fine-tune the exact look before downloading. Your original photo is never modified, because the filtered version downloads as a new file created entirely in your browser.
