Help, Support & Privacy Guide

Unlike traditional file websites that require uploading your documents to remote servers across the internet, 99b.in processes files directly on your computer or phone.

When you select a PDF or spreadsheet, your web browser opens and modifies the file locally in your device's memory. Your sensitive financial statements, tax forms, employee registers, and legal agreements are never transmitted or stored on external servers.

File Size & Document Recommendations

• Recommended file sizes: Up to 50 MB on mobile phones and tablets, and up to 200 MB on desktop computers.
• Password protection: If your PDF is encrypted with a password, unlock or remove the password first before converting or organizing.
• Instant clearing: Because your files are held only in temporary browser memory, closing or refreshing the tab clears everything immediately.
• Scanned pages: If your document consists of scanned photographs without selectable text, text extraction requires an OCR tool first.

Spreadsheets & Compliance Portal Delimiters

Our Spreadsheet to Delimited Text tool allows converting XLSX and CSV tables into specialized portal upload formats. You can select custom separators, commas, tabs, pipes, or portal standards such as EPFO ECR #~# commonly required by payroll, tax, and compliance reporting portals.
