What is Image Compressor?
Shrink JPG, PNG and WebP images to a smaller file size while you watch the result. The image is decoded and re-encoded by your browser's canvas, so the original file is never uploaded.
What is Convert Image?
Convert one PNG, JPG or WebP to another of those three in your browser, at the source pixel size. SVG can be opened and is rasterized to pixels. Animated GIF keeps the first frame only. There is no SVG export and no vector tracing.

Real-world examples
Shipping an API change
A backend engineer pastes a response payload into Image Compressor to get it readable, then switches to Convert Image to confirm the change behaves the way the ticket describes. Two tabs, under a minute, nothing uploaded.
Cleaning up a client hand-off
A file arrives from a client in the wrong shape. Convert Image handles the conversion or check, and Image Compressor produces the tidy version you actually send back. Because both run locally, client data never leaves the laptop.
Debugging in a hurry
Production is throwing an error and you have a blob of data and no context. Image Compressor tells you what you are looking at; Convert Image tells you whether it is correct. Together they replace a much heavier desktop toolchain.
