Frequently Asked Questions
Why merge PDFs before uploading to an online form?
Many portals — job applications, exam forms, government submissions — accept only a single PDF attachment. Merging your documents into one file lets you meet that single-file requirement without leaving anything out.
Will the merged PDF be small enough to upload?
Merging combines files without re-compressing them, so the result is roughly the sum of the inputs. If a portal enforces a size limit, merge first, then shrink the result with our Compress PDF tool.
Is it safe to merge sensitive documents for upload?
Yes. Merging happens entirely in your browser, so your documents — IDs, certificates, bank statements — never leave your device or touch a server.
Can I reorder pages before uploading?
Yes. Drag and drop the files to set the exact order before merging, so your combined PDF matches the sequence the form expects.
