What they have in common

Your files never leave your device. Some tools, like OCR or the AI background remover, download a small model at the start (about 10 to 20 MB) that is then stored in your browser; your file is never sent. You can check this by turning on airplane mode after the page loads. For more detail, read Is it safe to upload your documents to an online converter?.

We're also upfront about limits: when a tool doesn't rebuild a layout, doesn't validate an application or can make mistakes, we say so on its page.
