About Image Editor
Free browser-based image editing applies real-time adjustments using HTML5 Canvas filter API with brightness (-100 to +100), contrast (-100 to +100), saturation (-100 to +100), and blur (0-20px) controls. Offering six preset filters (Grayscale, Sepia, Invert, Vintage, Cold) alongside manual slider adjustments, the tool processes images entirely client-side without upload. Supporting JPG, PNG, WebP, and GIF inputs, it outputs edited PNG files suitable for social media, websites, presentations, and graphic design projects.
This solution serves social media managers enhancing photos for posts, bloggers adjusting image brightness/contrast for readability, content creators applying vintage/sepia effects for aesthetic consistency, and hobbyists experimenting with photo filters. Whether brightening underexposed photos for Instagram, converting color images to grayscale for professional presentations, applying sepia tones for nostalgic blog headers, or inverting colors for creative social media graphics, the tool delivers instant editing without desktop photo software installations.
