Frequently asked questions
Will compressing reduce PDF quality?
There's a trade-off — pick the higher-quality option if you need crisper images, or the smaller option to save more space.
How much smaller will my file get?
It depends on the file's contents, especially embedded images, but most PDFs shrink noticeably.
Is this safe for confidential documents?
Yes — compression happens locally in your browser, nothing is uploaded.
Which compression method should I pick?
The lighter option suits text-heavy documents; the stronger one helps most on PDFs that are mostly large images or scans.
Does this work well on scanned documents?
Yes — scans are usually mostly image data, so they often see the biggest size reduction.
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.
