Fire Effect Overlay - Online Add Flames to Photo

Simply drag and drop your photo onto the upload area, or click to browse your files. Once uploaded, choose your preferred flame style, adjust the position (bottom, top, sides, or surround), and fine-tune the intensity, height, and spread. The fire effect is rendered in real-time on the canvas. When satisfied, click Download Image to save your creation as a PNG file.

Yes! This online fire effect overlay tool is 100% free with no hidden costs. There are no watermarks, no subscription requirements, and no limits on how many photos you can edit. All processing happens directly in your browser — your images are never uploaded to any server, ensuring complete privacy.

The tool supports JPG, PNG, and WebP formats for upload. Maximum file size is 10MB. For downloading, the output is always PNG format to preserve the highest quality with transparency support. If you need other formats, you can convert the downloaded PNG using any image converter.

The flame effects are procedurally generated using multi-layered gradient algorithms that mimic real fire behavior — white-hot cores transitioning through yellow and orange to deep red edges. With the Screen blend mode (default), the flames blend naturally with your photo, creating a convincing overlay. Spark particles add extra realism. For best results, use photos with darker backgrounds where flames naturally stand out.

Absolutely! The tool is fully responsive and works seamlessly on smartphones and tablets. On mobile devices, the controls stack below the preview area for easy thumb access. All features — including drag-and-drop upload (tap to browse), style selection, sliders, and download — are optimized for touch interaction. Both iOS and Android are supported.

Not at all. The tool works non-destructively — your original photo file is never modified. All fire effects are rendered on a separate canvas layer in your browser's memory. You can toggle the fire effect on/off using the "Hide Fire" button to compare with the original. Only when you click download does a new composite image get created, leaving your original file untouched.

We offer 6 distinct flame styles:
🔥 Classic Fire — Traditional red-orange-yellow flames
🔥 Intense Fire — Hotter, brighter, more aggressive flames
💎 Blue Flame — Cool-toned ethereal blue fire
🧪 Green Magic — Mystical green flame effect
💜 Purple Dark — Dark, moody purple fire
✨ Golden Glow — Warm golden-amber flames
Each style can be further customized with position, intensity, height, and spread controls.

For the most natural-looking results: (1) Use the Screen blend mode (default) for realistic glow. (2) Keep intensity between 50-80% — full intensity can look artificial. (3) Match flame position to a logical light source in your photo. (4) Enable spark particles for added realism. (5) Use photos with darker backgrounds — flames pop best against dark scenes. (6) Adjust flame height to be proportional — 25-40% of image height usually looks most natural for bottom fires.

Your privacy is fully protected. This tool processes everything client-side in your browser using JavaScript and Canvas API. Your photos are never uploaded to any remote server, stored in any database, or shared with third parties. The entire process — from upload to rendering to download — happens locally on your device. You can even disconnect from the internet after the page loads and the tool will continue working.

Screen (default & recommended) — Dark areas of the flame become transparent, bright areas glow naturally. Best for realistic fire overlays.

Overlay — Increases contrast, making flames more dramatic with deeper shadows. Best for artistic edits.
Soft Light — Subtle effect, flames appear more transparent and ethereal. Ideal for gentle warmth additions.
