Free Image Shadow Tool - Add Drop Shadow Effects to Photos Online
Add realistic drop shadows and depth effects to images. Adjustable shadow blur, distance, angle, opacity, and color. Soft shadows, hard shadows, perspective shadows. Perfect for product photography, logo design, cutout images, and creating 3D floating effects.
What is Shadow Generator?
Our Image Shadow Tool adds professional drop shadow effects that make images appear to float above the background. Customize shadow blur (0-100px softness), distance (shadow offset from image), angle/direction (0-360°), opacity (subtle to dramatic), and color (black for natural, colored for creative effects). Choose from shadow presets: soft shadow (subtle realistic depth), hard shadow (sharp defined edge), long shadow (flat design style), and perspective shadow (3D depth illusion). Perfect for product photography, logos, cutout images, floating card effects, and UI mockups.
The tool works especially well with transparent PNG images - cutout products or logos with no background receive shadows that follow their exact shape rather than rectangular box shadows. This creates realistic depth effects where shadows appear naturally behind objects. For images with backgrounds, the shadow applies to the entire image rectangle, creating a floating card or polaroid effect popular in modern web design.
Professional use cases include e-commerce product photos (shadows make products look physical and tangible rather than flat), logo design and branding (subtle shadows add depth without overwhelming), app and web mockups (floating UI cards with shadows create hierarchy), social media graphics (shadowed elements stand out in feeds), and presentation slides (images with shadows separate from background). Shadows improve visual hierarchy by making important elements appear closer/above others.
Soft shadows (high blur, medium opacity) create natural realistic depth mimicking real-world lighting. Hard shadows (low blur, high opacity) create dramatic bold effects for modern design. Long shadows (extreme distance, low opacity) achieve flat design aesthetic popular in material design. Perspective shadows (skewed/transformed) create optical illusions of 3D space. Export as PNG to preserve shadow transparency, allowing layering in other designs. All processing happens locally - images stay private.

Frequently Asked Questions
Everything you need to know about Shadow Generator
Realistic shadows have: moderate blur (10-20px for soft shadows, 2-5px for hard), 20-40% opacity (not pure black), subtle distance (5-15px offset), angle matching light source (45° is natural, top-right is common). Avoid: pure black at 100% (too harsh), excessive blur (looks fake), zero blur (unrealistic hard cutout), random angles. Nature shows blur increases with distance from surface. For floating effect: large blur + distance. For surface contact: minimal blur + distance. Shadow color should be dark gray (#333) or warm/cool toned, not pure black. Test against white and colored backgrounds.
Drop shadow is directional - simulates light source casting shadow in specific direction (angle parameter matters). Creates realistic depth suggesting image lifts off background. Outer glow is non-directional - emanates equally in all directions around object like halo or glow effect. No angle setting. Use drop shadow for realistic product photos, mockups, buttons (simulates light/depth). Use outer glow for artistic effects, highlighting important elements, creating neon/light effects. Outer glow typically uses bright colors, drop shadows use dark colors. Drop shadow is far more common for professional designs.
Identify light source in image - observe highlights and existing shadows on objects. If light comes from top-right (most common in photography), set shadow angle to bottom-left direction (225°). Formula: shadow is opposite to light. Top light = bottom shadow (180°), right light = left shadow (270°). Match shadow length to light intensity - harsh direct light = shorter darker shadows (2-5px distance, 40% opacity), soft diffused light = longer softer shadows (10-20px distance, 20% opacity). Inconsistent shadow direction looks unnatural - stay consistent across all elements in composition.
Soft shadows (large blur radius 15-30px) suggest diffused studio lighting - looks professional, gentle, high-end. Best for: luxury products, cosmetics, fashion, artistic shots. Creates floating effect. Hard shadows (small blur 2-5px) suggest direct harsh light - more dramatic, graphic, clear. Best for: tech products, tools, items where clarity matters, minimalist designs. Most e-commerce uses soft shadows (20px blur, 20% opacity, 10px offset) for safe professional look. Very expensive products often use almost no shadow (pure white seamless). Match shadow style to brand aesthetic.
Yes - perspective shadow (sometimes called cast shadow) requires distorting shadow shape to simulate shadow cast onto a surface at angle. This is more complex than circular drop shadow. Set angle (usually 45-70°), then stretch shadow horizontally/vertically to simulate ground plane. Shadow should be darkest near object, fade with distance (gradient opacity). For realistic ground shadows: angle 45-60°, horizontal stretch 2-3x, vertical fade, blur increases with distance. Most product photos use simpler drop shadow rather than full perspective shadow unless showing object on specific surface.
Yes, completely private. All shadow rendering happens locally in your browser using JavaScript and HTML5 Canvas. Your images are never uploaded to any server, never transmitted over the internet, and never stored or logged. The shadowed image is generated entirely on your device. You can even use this tool offline after the page loads. Your original and shadowed images remain fully confidential.
