Question 1

Is it safe to upload confidential legal or tax documents to these PDF tools?

Accepted Answer

Yes. Unlike traditional online PDF converters that upload your files to external cloud servers, ToolByte processes everything 100% locally in your browser memory using client-side JavaScript. No file bytes ever leave your device.

Question 2

Are there page limits or file size caps on PDF merging and splitting?

Accepted Answer

Because all processing happens on your local device hardware, there are no artificial server-imposed page or file limits. Performance depends solely on your computer available RAM.

Question 3

How does the visual PDF page extractor work?

Accepted Answer

We render crisp page thumbnails using a sandboxed WebAssembly/Canvas renderer (pdfjs-dist). You can visually click pages or enter comma-separated ranges (e.g., 1-3, 5, 8-10) to extract them into a single PDF or bundle them into a zip file.
