How to use this tool

  1. Upload any photograph (JPG, PNG, WebP, SVG) by dragging and dropping it into the workspace, browsing files, or pasting directly from your clipboard (Ctrl+V / Cmd+V).

  2. Drag the interactive focal reticle directly on the canvas preview to align the origin of the zoom blur with your main subject (e.g., a person's eyes, a sports car, or a vanishing point).

  3. Select a curated motion preset such as 'Hyper Speed Rush', 'Gentle Cinematic Pulse', 'Off-Center Action Pan', or 'Radial Vortex'.

  4. Adjust Blur Strength (0px to 100px) to control how aggressively pixels stretch outward along the focal radial axes.

  5. Toggle the Sharp Center Mask and adjust its radius and feather sliders to keep your primary subject pin-sharp while the background rushes past in heavy motion blur.

  6. Optionally introduce Vortex Swirl to impart a dynamic rotational spin around the focal center for dizzying action perspectives.

  7. Inspect the live interactive canvas preview using zoom and before/after comparison tools.

  8. Export your final high-speed motion artwork at full native source resolution as a lossless PNG or high-quality JPEG.

Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

The zoom blur engine executes 100% client-side using hardware-accelerated HTML5 Canvas 2D multi-scale radial sampling. By iteratively sampling and compositing the image at fractional scales radiating outward from your chosen focal point $(X, Y)$, it simulates the physical optical zoom burst achieved when rotating a camera's zoom ring during a slow shutter exposure.
In photography, an optical zoom burst can often blur the entire image including the main subject. The Sharp Center Mask uses a radial feather gradient to isolate your focal subject, preserving 100% of its sharp textures and details in the center while accelerating the radial motion blur across the surrounding background.
Standard zoom blur expands or contracts pixel paths straight along radial lines emanating outward from the focal center point, conveying linear forward velocity. Radial Vortex blur adds an angular rotational displacement at each sampling step, creating a swirling spiral tunnel or dizzying vertigo effect.
Action sports, fast-moving vehicles, city traffic, nighttime streetlights, concerts, architectural tunnels, and perspective leading lines produce the most breathtaking results. Placing the focal center at the vanishing point of a street or corridor dramatically accentuates the illusion of extreme speed.
No. While the live canvas preview is dynamically optimized for real-time interactive positioning at 60 FPS, the export engine renders directly onto an offscreen canvas matching your image's 100% native pixel dimensions with high-precision radial sampling steps.
Never. All geometric scaling, multi-pass accumulation, and image encoding occur entirely in your local browser memory. Zero photo bytes are transmitted over the network.
