Questions & answers
Will it pass strict validation?
PDFs with embedded fonts usually do. If your PDF uses fonts that aren't embedded, we'll warn you — those may fail strict validators such as veraPDF.
Are my files uploaded to your server?
No. This tool runs entirely inside your browser, so your files stay on your device. FilesForU never receives, stores or sees them.
