Are my uploaded photos safe and private?

Yes, completely. All image filters, sharpening, and contrast adjustments occur entirely inside your browser using HTML5 Canvas. Your photos are never sent to or stored on any server.

How does the sharpening algorithm work?

It applies an unsharp mask convolution kernel that boosts high-frequency edge contrast, making blurred details and textures crisper without over-saturating flat areas.

Can I compare before and after results?

Yes, an interactive split slider allows you to drag across the image in real time to compare the original photo with your enhanced version.

What image formats are supported?

You can upload JPG, PNG, WebP, BMP, and GIF images and export high-resolution PNG or JPG files.

About the Image Enhancer

The Image Enhancer is designed to perform advanced image processing directly in your web browser. This means your files are never uploaded to a remote server, ensuring complete privacy and significantly faster processing times.

How it Works

Client-Side Rendering: Utilizes the HTML5 Canvas API to manipulate pixels locally on your device.
Format Support: Handles standard web formats including JPEG, PNG, WebP, and in many cases, SVG and GIF.
Zero Compression Loss: Unless explicitly converting or compressing, the original image resolution and quality are preserved.

Security Note: Because all processing happens locally, this tool is safe for handling sensitive or proprietary imagery.
