Frequently Asked Questions

Quick answers about controls, features, accuracy, and local browser saving.

How does client-side PDF merging work without uploading files?
RapidWebApp combines your PDF documents directly inside your web browser's memory using WebAssembly and pdf-lib. Each document is decoded locally, its page tree is cloned into a new document in your chosen order, and the combined file is saved immediately. No file data ever leaves your device.
Can I reorder files before merging?
Yes! You can use the Move Up (▲) and Move Down (▼) buttons on each document card to arrange the exact page sequence you want before generating the merged PDF.
Is there a limit on file size or number of PDFs?
Because processing runs entirely on your local computer, there are no artificial server upload caps or paywalls. You can merge dozens of documents with hundreds of pages in seconds.
Are bookmarks and form fields preserved?
All standard text, images, vector graphics, and page layouts are preserved in full fidelity during the merge process.
