Slit-scan photography is a technique where a narrow slit is used to capture an image over time, creating surreal distortions. Each row (or column) of the final image captures a slightly different moment, resulting in stretched, warped, or time-shifted visuals. This digital tool simulates that analog process by offsetting pixel rows or columns based on mathematical waveforms.

Simply upload a photo by clicking or dragging it into the upload area. Choose your scan direction (horizontal or vertical), pick a waveform type, and adjust the intensity, frequency, and phase sliders. The preview updates in real-time. Once satisfied, click Download to save your distorted image at full resolution.

For glitch art, try the Random waveform with high intensity (150-250px) and the Wrap edge mode. For vaporwave or dreamy looks, use the Sine waveform with moderate intensity (40-80px), low frequency (0.5-1.5), and the Mirror edge mode. Enable animation for dynamic, flowing distortions perfect for music visuals.

Absolutely! The tool is fully responsive and works on iOS and Android devices. You can upload photos from your camera roll, adjust all parameters with touch-friendly sliders, and download the results directly to your phone. The canvas rendering is optimized for mobile performance.

Clamp stretches the edge pixels when offset goes beyond the image boundary, creating smooth extensions. Wrap loops the image so pixels that exit one side re-enter from the opposite side — great for seamless patterns. Mirror reflects pixels back, creating symmetrical ripples. Each mode produces a distinctly different aesthetic.

The tool accepts JPG, PNG, and WebP images. There's no strict size limit, but for the best experience we recommend images under 20MB. The preview canvas renders at up to 700px wide for smooth performance, while the download button saves your result at the original image resolution.

Regular photo warping typically applies a uniform transformation across the image. Slit-scan is unique because it shifts each row or column independently based on a waveform function, creating time-displacement-like effects. This mimics the analog slit-scan technique where different parts of the image are captured at different moments, resulting in organic, flowing distortions impossible to achieve with standard warp tools.
