Frequently asked questions
Are my PDFs uploaded to a server?▾
No. Merging runs entirely in your browser using a WebAssembly-powered PDF library. Your documents never leave your device.
How many PDFs can I merge?▾
As many as you like, up to 100 MB total. Since it runs locally, the practical limit is your device's memory.
Does merging reduce quality?▾
No. Pages are copied into a new container losslessly — content, fonts and resolution are untouched.
