Questions
FAQ
Is there a file size limit?
OfflinePDF's Merge PDF tool allows up to 300 MB per file and 600 MB total. Heavier tools such as Compress PDF and OCR PDF enforce lower caps because they use more browser memory.
Are my files uploaded anywhere?
OfflinePDF's Merge PDF tool combines files entirely in the browser using WebAssembly; no file is uploaded to any server during the process.
What if one of my PDFs is password-protected?
A password-protected PDF must be unlocked before merging: open it in a PDF viewer, enter the password, save or print a copy without a password, then run OfflinePDF's Merge PDF tool — or use OfflinePDF's Remove Password tool first.
