Doesn't Xodo process files in the browser too?

Many of its web tools do — Xodo publishes a per-tool list, and editing, redaction, merge/split and form-fill run client-side. We won't pretend otherwise. The tools that upload are the high-value ones: PDF→Word/Excel/PPT conversion, compression, Xodo Sign, and the AskPDF AI. AttachKit runs those in your browser too, so nothing is uploaded for any tool.

Is Xodo Sign more legally valid than AttachKit's signatures?

No — both are standard electronic signatures (ESIGN/UETA; neither offers qualified/QES signatures). The difference is architecture: Xodo Sign stores your document in its cloud and verification happens in its platform; AttachKit produces an offline-verifiable signature anyone can check on any device, with no account.

What does Xodo do better?

Its native mobile and desktop apps and local annotation are strong, and it has cloud sync (Xodo Drive) and enterprise trust signals (SOC 2 on Xodo Sign) that a browser-only tool doesn't. AttachKit's edge is keeping every tool — including conversion, compression, signing and AI — in your browser, plus saved-profile autofill and verifiable signatures.

AttachKit vs. Xodo — for the tools where uploading actually matters

Xodo: Apryse's cross-platform PDF suite — strong apps, web tools, Xodo Sign, and AI.

Xodo (owned by Apryse) is a mature, polished PDF suite — strong native apps, 40+ web tools, a cloud e-signature product (Xodo Sign), and an AI assistant (AskPDF). Credit where it's due: Xodo's apps edit on-device, and it says many of its web tools run in your browser too. The difference shows up on the tools people most want kept private — PDF→Word/Excel conversion, compression, e-signature, and AI — which upload your file to Apryse's servers. AttachKit runs all of those in your browser, with nothing uploaded.

Why pick AttachKit for these cases

The tools you'd most want kept private — convert, compress, e-sign, AI — upload to Apryse on Xodo; on AttachKit they run in your browser.
AI auto-fill from a saved profile, which Xodo doesn't offer.
No ~1-action-per-day cap on AttachKit's free in-browser tools.
Offline-verifiable signatures that don't depend on a signing platform.
