How to choose the right image tool

If the picture is the wrong shape, start with Crop Image. If the dimensions are wrong, use Resize Image. If the file is too large, use Compress Image. If the format is wrong for a website or upload form, use Convert Image. For whole folders, use Bulk Image Resizer.

Specialist tools are here too: Image to Text OCR for extracting text, Favicon Generator for website icons, Pixel Art Maker for retro artwork, and Image to ASCII for text-art experiments.
