Compress an image, merge a PDF, generate a code. Every tool here works inside your browser — no upload wait, no file size cap, and no copy of your data on anyone's server.
Conventional online converters send your file to a server, process it, and hand it back. Here the work happens on your own machine — you can watch the network tab stay silent.
Processing starts the moment you drop a file. A 40 MB image doesn't need to travel anywhere first, so large batches finish in the time an upload would have taken.
There is no server bill to keep down, so there is no reason to cap file size or ask you to sign up after three conversions. Your device's memory is the only ceiling.
