Image Converter & Metadata Stripper Convert, resize and compress pictures, and see or remove the Exif metadata inside them, including the GPS coordinates a phone writes into every photo.

Background Remover Cut the background out of a picture and save it as a transparent PNG. Colour based selection with tolerance, soft edges, fringe cleaning and brushes to fix the rest.

Colour Replacer Swap one colour in a picture for another, or make it transparent, with a slider for how close a colour has to be. Shading and soft edges survive the swap.

Favicon & App Icon Generator One picture in, every icon a site needs out: favicon.ico, the PNG sizes, the Apple touch icon, maskable Android icons, site.webmanifest and the HTML to paste.

Meta Tags & Social Preview Write the title, description and image once and watch the link take shape on Google, X, Discord, Slack and Facebook, then copy the Open Graph and Twitter tags.

Diff Tool Compare two texts line by line with the changed words picked out, or parse both first so reordered keys and reformatted JSON stop counting as changes.
