Frequently Asked Questions

Is there a file limit size for merging PDFs?

Because ToolTari works entirely client-side using browser memory, file sizes are restricted only by your computer’s RAM resources. For optimal performance, we recommend keeping combined files below 350MB.

Are my files uploaded when using this tool?

No. Your files are processed 100% locally inside your web browser. None of your document data is sent to external servers, guaranteeing maximum security and privacy.

Does this tool work on mobile devices?

Yes. The entire responsive dashboard operates natively on Android and iOS browsers, making it extremely easy to combine files directly from your smartphone or tablet.
