Frequently Asked Questions

Is it safe to merge confidential documents with FolderBit?
Yes. In-browser merges are processed 100% locally on your device via client-side Web Workers. Your documents are never uploaded to any remote server, stored in temporary queues, or visible to third parties.
Can I reorder files before combining them?
Yes. You can drag and drop file cards in the preview area to arrange the exact page and document sequence before generating the merged file.
Will merging reduce the quality of my PDF text or images?
No. FolderBit merges the underlying PDF object trees without re-encoding or rasterizing pages, ensuring that high-resolution vector text, embedded color profiles, and sharp diagrams remain 100% crisp.
Do I need to install any software or extensions?
No software, plugins, or extensions are needed. FolderBit works in any modern web browser across Windows, macOS, Linux, Chromebooks, iPhones, and Android devices.
Is there a limit on how many PDFs I can merge?
For client-side merges, there is no arbitrary file count limit. You can combine dozens of documents up to your device memory limits completely free.
