FAQ
How do image tools work?
Image tools use the HTML5 Canvas API and browser-native image processing to resize, convert, and manipulate images directly in your browser without uploading to any server.
Are uploaded images stored?
No. Images are processed entirely in your browser's memory and are never uploaded to any server. Once you close the tab, all image data is gone.
What image formats are supported?
Most tools support PNG, JPEG, WebP, and SVG input. Output format options depend on the specific tool.
