Frequently Asked Questions
Can I merge JPG images with PDF files?
Yes! Our merger allows combining PDF documents and photo files (JPG, PNG) into a single document. Images are automatically formatted into standard document pages.
Is there a maximum file size or limit?
Because everything executes locally on your device's memory without server transmission, you can merge as many files as your device's RAM comfortably supports.
Will my confidential PDF documents stay private?
Completely private. No files, metadata, or rendered page images are sent over the network to any server. Processing takes place 100% inside your browser session.
Can I rotate files or insert blank separator pages?
Yes. Every uploaded file card includes a 90° clockwise rotation button. You can also click "Add Blank Page" to insert clean divider sheets anywhere in the sequence.
