Frequently Asked Questions
Everything you need to know about FileFryer's client-side PDF Merger.
Are my sensitive documents uploaded to any server or cloud?
No, absolutely not. FileFryer operates completely client-side in your web browser using modern JavaScript and WebAssembly via pdf-lib. Not a single byte of your PDF files is ever transmitted over the network or stored in external databases.
Can I choose which pages from each PDF to include?
Yes! By default, every document includes all pages. You can type specific page numbers or ranges, such as 1-4, 2, 5, 8, or combinations like 1-3, 7-9 to extract only what you need.
Is there a file size limit or max document count?
Because FileFryer executes in your browser sandbox, the only real boundary is your system's available memory. You can merge dozens of files and hundreds of pages without running into commercial server-imposed artificial restrictions.
Does merging reduce the resolution of images or text in my PDFs?
No. Page objects, vector text, embedded fonts, and graphics are copied cleanly into the newly constructed PDF dictionary without rasterization or downsampling. Your documents retain their native fidelity.
Can I reorder or rearrange documents before merging?
Yes. Use the up and down arrow controls next to each uploaded PDF to arrange your documents in the exact order you want them stitched together.
Can I merge password-protected PDF files?
Encrypted PDFs must be unlocked before merging. You can use FileFryer's built-in PDF Unlock tool to remove passwords client-side first, then combine them seamlessly.
