Frequently asked questions
Is there a limit on how many PDFs I can merge?
No — merge as many files and pages as you need in one go.
Does merging PDFs upload my files anywhere?
No, merging happens entirely in your browser; files never leave your device.
Can I change the page order before merging?
Yes, use the up/down arrow buttons next to each file before clicking Merge.
Can I merge PDFs with different page sizes?
Yes — each page keeps its own original size and orientation in the merged file.
Is there a file size limit?
No hard limit — since everything runs in your browser, the practical ceiling is your own device's memory, not a server quota.
Your files are never uploaded. Gotool.xyz runs entirely as JavaScript in your browser. Your files are processed in memory and never touch a server — nothing to breach, nothing to clean up. Close the tab and it's like it never happened. The only thing we count is which tool ran (just the name, e.g. "merge") so we know what people find useful — never your file, its name, its size, or anything in it.
