Frequently Asked Questions
What is a rain overlay effect? ▼
A rain overlay effect digitally adds realistic falling rain onto your photos. It simulates raindrops with adjustable density, size, speed, and wind angle, giving your images a moody, atmospheric rainy-day look — all processed locally in your browser.
How do I add rain to my photos using this tool? ▼
Simply upload your photo by clicking the upload area or dragging an image onto the preview canvas. The rain effect starts automatically. Adjust the sliders to fine-tune density, drop size, speed, wind angle, and opacity. When satisfied, click "Save Image" to download your edited photo.
Is my image uploaded to any server? ▼
No. This tool runs entirely in your browser using client-side JavaScript and HTML5 Canvas. Your images are never uploaded, stored, or transmitted anywhere. Complete privacy is guaranteed — you can even use it offline after the page loads.
What image formats are supported? ▼
The tool supports JPG, PNG, WebP, and most common image formats. The output is always a high-quality PNG file that preserves transparency if your original image has it. Maximum recommended file size is 20MB for smooth processing.
Can I use this rain overlay tool on my phone? ▼
Absolutely! The tool is fully responsive and works on all modern devices — smartphones, tablets, and desktops. The interface adapts to smaller screens, and touch-friendly sliders make adjusting rain parameters easy on mobile.
What are the best uses for rain effect photos? ▼
Rain effects are perfect for creating moody social media posts, cinematic scene edits, artistic portraits, weather-themed designs, book covers, and atmospheric landscape photography. The adjustable parameters let you create anything from a light drizzle to a dramatic storm.
How does the "Cool Tone" and "Vignette" feature work? ▼
Cool Tone adds a subtle blueish filter that mimics the natural color temperature of overcast, rainy days. Vignette darkens the edges of the photo to draw focus to the center, enhancing the dramatic atmosphere. Both are optional and fully adjustable.
