Frequently Asked Questions
Yes, completely safe. utool processes your files locally inside your browser using WebAssembly. Your data is never sent to our servers, logged, or stored anywhere.
No server-imposed limit. utool processes files in your browser using your own device memory. Practical limits depend on your device RAM — most computers can handle files up to several gigabytes.
Cloud tools make you upload large files to their servers, which takes time and consumes your bandwidth. utool bypasses this entirely — your large file is processed instantly without any upload wait.
utool processes large files in streaming chunks to avoid freezing your browser tab. For very large files (1GB+), we recommend closing other heavy browser tabs to free up memory.
