Frequently Asked Questions
Everything you need to know about trimming videos online
How do I combine multiple PDF files into one document online?
- Simply drag and drop your PDFs into our free online PDF merger. You can upload and combine up to 100 files at once (up to 100MB each). Once uploaded, click merge, and your combined document will be ready to download instantly.
Can I rearrange the order of the files before joining them?
- Yes! After uploading your multiple PDF files, simply drag and drop the file thumbnails to reorder them. The final joined PDF will seamlessly follow your exact, customized sequence.
Do I need to download Adobe Acrobat to merge PDFs?
- No software installation or paid subscription is required. Our free PDF binder works entirely in your web browser. You can seamlessly combine PDF files directly on your Mac, Windows PC, iPhone, or Android device.
Will merging PDFs mess up the formatting or page sizes?
- Not at all. Each page retains its original formatting and dimensions. If you are combining a standard A4 document with a US Letter-sized document, the merged PDF will flawlessly contain both mixed page sizes without any stretching or distortion.
What happens to my bookmarks, hyperlinks, and fillable forms?
- Unlike basic PDF joiners that flatten documents and break links, our advanced tool preserves all interactive elements. Bookmarks, clickable hyperlinks, fillable form fields, and annotations from all your source files are perfectly carried over to the final merged document.
Can I combine password-protected or locked PDF files?
- Yes, as long as you know the password to open them. You will be prompted to enter the password to unlock the encrypted file during the upload process. Once unlocked, it will merge normally with the rest of your documents.
Is it safe to merge confidential business documents online?
- Yes, we use bank-grade security for all file processing. Your documents are uploaded via an encrypted SSL connection and are automatically and permanently deleted from our servers within 5 hours. We never store, read, or share your private data.
