Technical FAQ

Do my files ever touch your server?
Never. We use the browser's local memory and JavaScript-based PDF engines to handle everything on your device.
Is there a limit to how many PDFs I can merge?
We do not impose any artificial limits. The only constraint is your computer's RAM and processing power.
What is the maximum file size supported?
While we don't set a limit, browsers typically handle up to 2GB smoothly. Beyond that, performance depends on your disk and memory.
Does merging affect the quality of images in my PDF?
No. Our "Copy Object" method ensures that every image, font, and vector is preserved in its original resolution.
Which browsers are supported?
Our tools work on all modern browsers, including Chrome, Firefox, Safari, and Edge. We recommend keeping your browser updated for maximum speed.
