Practical guide to Image converter & editor

Use one preview-driven workspace for format conversion, compression, resizing, precise cropping, and extracting colors for CSS or design tokens.

Best uses and outputs

Choose JPG for small photographic files, PNG when transparency matters, or WebP for a balance of quality and size.
The palette tab reports HEX, RGB, HSL, and pixel share, then exports the colors as CSS variables or JSON.

A reliable workflow

Check the source dimensions first, choose the operation tab, and preserve the aspect ratio unless an exact layout requires otherwise.
Compare the result preview and file size before downloading; palette users should also check whether frequency or brightness sorting fits the intended design.

Limits and troubleshooting

A browser can only decode formats supported by its image engine, and very large pixel dimensions can exhaust tab memory even when the file size is small.
Animated GIF input is treated as one decoded frame, while JPG output fills transparent pixels with the selected background color.
