Are my sensitive PDF documents uploaded to your servers?

No! Unlike conventional cloud converter tools, our PDF merger runs 100% locally inside your web browser using WebAssembly and pure client-side JavaScript. Your files never touch or pass through any remote server.

How many PDF files can I merge at once?

You can merge up to 20 PDF documents in a single batch with zero daily limits or account registration required.

Does merging reduce the text quality or visual sharpness of the PDF?

No. The engine preserves 100% of the original vector fonts, high-resolution imagery, and embedded formatting without applying destructive lossy compression.

Why Client-Side Document Security Matters

Standard cloud PDF converters upload your confidential records directly to their remote web servers. If your documents contain sensitive personal data like financial statements, ID records, tax numbers, or internal contracts, cloud uploads present unnecessary compliance and data leakage concerns.

WebTools operates on a 100% Client-Side Architecture. The engine executes inside your browser using pure JavaScript and WebAssembly. Your files are processed in local memory and never transmitted over the internet, providing ironclad privacy.

Frequently Asked Questions (FAQ)

Is there a maximum file size limit for merging?

Because files are processed directly on your computer's RAM rather than on remote servers, you can merge large PDFs spanning tens of megabytes smoothly without artificial paywalls or file caps.

Will combining PDFs affect font clarity or graphic quality?

Not at all. The underlying PDF streams and vector typography are copied losslessly 1:1, guaranteeing identical crispness and printable clarity.

What if my PDF file is password protected?

If your document is secured with an owner or user password, make sure to unlock or remove the password before importing it into the merger.
