Image Filters

About Image Filters - Free Online Photo Editor

Image filters are powerful tools that allow you to enhance, modify, and stylize your photos online without any software installation. This free image filter tool provides a comprehensive set of professional filters including brightness adjustment, contrast enhancement, saturation control, hue rotation, blur effects, grayscale conversion, sepia tone, and color inversion. All filters can be adjusted in real-time with instant preview, making it easy to achieve the perfect look for your images. No watermark, no registration required, and completely free to use.

What filters are available?

This tool provides 8 professional filters: Brightness (0-200%), Contrast (0-200%), Saturation (0-200%), Hue Rotation (0-360°), Blur (0-20px), Grayscale (0-100%), Sepia (0-100%), and Invert (0-100%). You can combine multiple filters to create unique effects.

How does real-time preview work?

As you adjust any slider, the filter is immediately applied to the preview canvas. This allows you to see the results in real-time and fine-tune your settings before downloading the final image. The preview uses CSS filters and canvas rendering for smooth, instant feedback.

What is the difference between Sepia and Grayscale?

Grayscale converts the image to black and white by removing all color information. Sepia adds a warm, brownish tone to create a vintage or antique photograph effect. Sepia is often used for nostalgic or artistic purposes.

Can I combine multiple filters?

Yes! You can adjust multiple filter sliders simultaneously. For example, you can increase brightness while also adding a sepia tone and slight blur. The filters are applied in combination, allowing for endless creative possibilities.

What does Hue Rotation do?

Hue Rotation shifts all colors in the image along the color wheel. A value of 0° shows the original colors, 180° shows complementary colors, and 360° returns to the original. This is great for creating color variations or artistic effects.

Does applying filters reduce image quality?

The filters are applied using high-quality canvas operations that preserve image detail. However, extreme filter values (especially high blur or very low brightness) may affect perceived quality. The output uses 95% quality JPEG encoding to maintain good file size while preserving visual quality.

What image formats are supported?

This tool supports all common image formats including JPEG, PNG, WebP, BMP, and GIF. The filtered image will maintain the same format as the original input image.

What are the size limits?

Maximum input file size is 10MB. Images of any dimensions are supported, though very large images may take longer to process. The filtered image maintains the same dimensions as the original.
