Why these tools work differently
Almost every online image tool uploads your file to a server, processes it there and sends it back. That is fine for a holiday photo, and a strange thing to do with a passport scan or a screenshot of your bank account — which is exactly what people use these tools for, because upload forms demand very specific file sizes.
Imgnest does the work in the browser instead. Canvas handles resizing and re-encoding, and WebAssembly runs the same compiled codecs a desktop application would use. Your file is read from disk by the page, processed in memory, and written back out as a download. It never travels anywhere — you can load a tool, disconnect from the internet, and it keeps working.
Because processing costs us nothing, there is also nothing to ration: no queues, no daily caps, no batch limits and no watermarks on your results.
