Frequently Asked Questions (FAQ)
How does merging multiple images into a single PDF work?
When you select PDF as the output format and check "Merge into single PDF", the tool reads the dimensions of each image and creates a custom-fit multi-page PDF document. You can adjust the order of pages using the sorting buttons in the queue before compiling.
Is there a limit on how many images I can convert to PDF at once?
There is no preset software limitation on the file count or size. The compiler operates entirely in your system RAM, meaning you can process as many images as your computer’s browser can handle.
Are my images secure when converting to PDF?
Yes, absolutely. ImagePlumber compiles and converts all files locally using JavaScript (jsPDF and HTML5 Canvas). No files are uploaded, stored, or processed on any backend server, keeping your private documents completely secure.
