Frequently Asked Questions

Quick direct-answer guides about using this utility tool locally and securely.

How do I find what changed between two PDF versions without reading both fully?
Upload both files to KuberAgent PDF Compare tool — it automatically highlights every addition, deletion, and modified word between them in seconds, so you never have to read both documents manually.
Is it safe to compare confidential PDF contracts online?
Most online tools upload your files to their servers — KuberAgent does the opposite. Both documents are compared entirely inside your browser's RAM and never leave your device, making it safe even for sensitive legal or financial documents.
How do I check if someone secretly edited my PDF?
Upload the original and the version you received — the tool immediately flags every word change, deletion, and visual modification. If anything was altered without telling you, it shows up instantly.
What is the difference between Visual Diff and Text Diff when comparing PDFs?
Text Diff catches word-level changes in the actual content — perfect for contracts and reports. Visual Diff compares both pages as images and catches layout shifts, font changes, or image swaps that text alone would miss. Using both together gives you a complete picture.
Can I compare two PDF files without Adobe Acrobat or any software?
Yes — no Adobe subscription, no software download, no account needed. Open the tool in your browser, upload both PDFs, and your comparison report is ready in seconds.
How do I compare a PDF contract to find exactly what the other party changed?
Upload the original draft and the version they sent back — every insertion is highlighted in one color and every deletion in another, so you can review all changes in one glance without a lawyer having to read both versions line by line.
Can I compare two PDFs that have different page counts?
Yes. The tool handles unequal page counts and lets you toggle page-by-page — so even if one version has extra pages added or removed, you won't miss a single change.
How do I compare scanned PDF documents to find differences?
Use Visual Diff mode — it renders both pages as images and highlights pixel-level differences in red, so even scanned files with no extractable text get a full comparison.
How long does it take to compare two large PDF files online?
Most comparisons finish in seconds — because everything runs locally in your browser, there's no server upload wait time, even for large multi-page documents.
Do free PDF comparison tools upload my files to their servers?
Most do — tools like PDF24 and ilovepdf process files on their servers. KuberAgent Compare PDF tool is different: everything runs inside your browser only, so your files are never uploaded anywhere.
