Before you upload to Add Page Numbers to PDF

Check the file you are about to process, especially when it contains contracts, IDs, invoices, payroll details, legal drafts, school records, or client information. FileLumo is designed for quick no-signup workflows, but the safest document workflow still starts with choosing the right file and keeping an untouched original copy.

• Keep a master copy before editing, compressing, converting, or protecting a document
• Remove pages you do not need to share before uploading sensitive packets
• Use a clear filename for the downloaded result so drafts and final copies do not get mixed up

Privacy, limits, and output quality

Most PDF jobs are simple, but edge cases happen: very large scans, unusual fonts, password-protected files, embedded images, and old PDF versions can change the output. After processing, open the result once before sending it to a client, school, court portal, or upload form. Server-side workflows use TLS in transit. FileLumo does not store your files — download your result to keep a copy.

• Use medium or balanced settings first when quality matters more than the smallest possible file
• For strict upload limits, compare the final file size against the portal requirement before submitting
• For confidential documents, review your organization policy before using any third-party online tool
