Frequently Asked Questions
What image editing tools work in the browser?
Modern browsers support the Canvas API, WebGL, and the File API, which together enable flip, crop, watermark, collage, pixel diff, and color extraction — all without uploading files to a server.
How do I flip an image online?
Load your image in an online flipper tool, choose horizontal or vertical, and download the result. The transformation happens via Canvas API's scale(-1, 1) or scale(1, -1) transform. No upload needed.
How do I add a watermark to an image?
Use an image watermark tool that lets you place text or a logo overlay. Set opacity, position, font size, and rotation. The Canvas API composites your watermark onto the source image at download time.
How do I compare two images?
A pixel diff tool reads both images into Canvas, subtracts their RGBA channel values pixel by pixel, and highlights differences above a threshold. Libraries like pixelmatch make this precise and scriptable.
How do I convert an image to ASCII art?
The tool samples each pixel's luminance, maps it to a character from a density string like '@#S%?*+;:,. ', then prints the character grid. Width controls resolution; color mode uses ANSI escape sequences.
