Vectowl is a free suite of browser-based image tools designed for designers, developers, content creators, and anyone who works with images regularly. Every tool runs entirely in your browser using JavaScript and the HTML5 Canvas API. Your images are never uploaded to any server, which means complete privacy and instant processing regardless of your internet speed.
Background Remover: Our flagship tool detects and removes solid-color backgrounds from logos, icons, and AI-generated images. It uses flood-fill analysis from the image borders to identify background pixels, with adjustable tolerance for handling gradients and slight color variations. A manual brush mode lets you paint exactly which areas to keep for complex images. Output includes auto-cropping and optional upscaling to 4K resolution using adaptive algorithms that detect flat graphics versus detailed illustrations.
Image Compressor: Reduce image file sizes by up to 90% using browser-native canvas compression. Choose between JPEG, WEBP, and PNG output formats with adjustable quality settings. Batch processing supports up to 50 images simultaneously, making it ideal for optimizing entire website image folders or social media content libraries.
Format Converter: Convert images between PNG, JPEG, WEBP, and BMP formats instantly. The converter automatically handles transparency when converting to formats that do not support it, filling transparent areas with white to prevent unexpected black backgrounds.
Image Resizer: Resize images to exact pixel dimensions with built-in presets for all major social media platforms including Instagram, Facebook, YouTube, LinkedIn, and Twitter. Aspect ratio locking prevents unintended distortion, and batch processing handles multiple images at once.
Color Palette Extractor: Extract dominant color palettes from any image using the median-cut quantization algorithm. Export palettes as CSS custom properties, JavaScript arrays, or Tailwind CSS configuration. Generate palettes of 5, 8, 12, or 16 colors depending on the level of detail you need.
Favicon Generator: Create website favicons in all standard sizes from a single source image. Generates 16×16, 32×32, 48×48, 180×180 (Apple Touch Icon), 192×192 (Android Chrome), and 512×512 (PWA splash screen) with ready-to-use HTML code.
