Why Use Our Client-Side PDF Tool?

Most online PDF tools require you to upload your sensitive files to a remote server. This creates a severe privacy risk and slows down the process. iLikeTOOL is different. We use advanced browser technologies to process your files right on your device.

  • Total Privacy: Your documents never leave your computer or phone.
  • Zero Waiting Time: No need to wait for uploads or downloads to process.
  • No Data Usage: Since files aren't uploaded, you save your internet bandwidth.

Frequently Asked Questions

Common questions about our PDF page numbering tool.

Can I customize the font and color?
Yes! Our tool provides options to select standard PDF fonts (Helvetica, Times Roman, Courier), adjust the font size in pixels, and use a color picker to match your document's branding.
Is my data really safe?
Absolutely. We use local WebAssembly processing. Your PDF file is read, modified, and saved entirely within your own browser. We have zero access to your files.
Does it work on Mac and Windows?
Yes, since this is a web-based utility, it works flawlessly on any operating system (Windows, Mac, Linux) and across all modern browsers including Chrome, Safari, and Edge.
Is this tool free?
100% free. There are no hidden fees, no daily usage limits, and we do not force you to create an account or add watermarks to your generated documents.
Can I process large PDF files?
Since processing is done locally on your device, the file size limit depends largely on your computer or phone's memory (RAM). Generally, files up to 100MB are handled very easily without crashing. We have a soft limit of 25MB for optimal performance.
Can I start numbering from a specific page?
Currently, this tool adds numbers to all pages starting from page 1. We are actively working on an advanced feature to let you choose a custom start page and page offset in a future update.
Success!
