Frequently asked questions
Answers about local processing, file limits, compression, accounts, and supported formats.
Are files uploaded?
No. Processing takes place in the browser; selected files are not sent to our servers.
Why can a file fail?
A file may be unsupported, damaged, password-protected, or too large for the memory available to the browser on your device.
Can every file be compressed?
No. Compression depends on how the file was created. We compare actual byte sizes and do not claim a reduction when the output is larger.
Do I need an account?
No account is required for the file tools.
Do tools change the original?
No. A tool creates a separate output file. Save it separately and keep the source if you need it later.
