Question 1

What PDF tools are available?

Accepted Answer

The PDF workspace includes: merge PDFs (combine multiple files), split PDF (extract a range of pages), rotate pages, compress PDF to reduce file size, add page numbers, add a watermark, remove pages, reorder pages, convert images to PDF, convert HTML to PDF, convert PDF pages to JPG images, and compare two PDFs.

Question 2

Are my PDFs uploaded to a server?

Accepted Answer

No. All PDF operations run in your browser using pdf-lib and PDF.js. Your files are never sent to DevBench servers. This makes the tools safe to use with confidential documents, contracts, or personal files.

Question 3

What is the maximum file size?

Accepted Answer

There is no hard server-side limit since processing is client-side. Practical limits depend on your device's available memory. Very large PDFs (over 100 MB) may be slow on devices with limited RAM. For most documents under 20 MB, processing is near-instant.

Question 4

Can I combine more than two PDFs?

Accepted Answer

Yes. The merge tool accepts multiple files — add as many PDFs as you need, reorder them by dragging, and merge them into a single file.
