About Image Tools

Image processing tools on useTool run entirely in your browser using the Web Canvas API. No image data is uploaded to a server — everything happens locally on your device. This means you can process sensitive images (screenshots with personal information, confidential design files) without any privacy concern, and results appear instantly regardless of your connection speed.

The four tools in this category cover the most common image preparation tasks for web publishing. Resize to match the exact pixel dimensions your layout requires. Compress to reduce file size for faster page loads and better Core Web Vitals scores. Convert between JPEG, PNG, and WebP based on the content type and target environment. Pick colors from any pixel to extract HEX, RGB, and HSL values for use in design work. Together they provide a complete browser-native image preparation workflow without any desktop software.
