PDF Studio vs Xodo Sign

PDF Studio is a PDF editor that maintains compatibility with the PDF Standard. It creates PDFs from scans, Microsoft Word, Excel, PowerPoint, text, and image files, and supports direct editing of PDF text, images, and shapes as well as redaction. OCR can recognize text and make searchable PDFs on Windows, Mac, and Linux. Pro adds batch processing for multiple documents and an Action Wizard for automating tasks. Integrations include DocuSign, Dropbox, Google Drive, and OneDrive; cloud documents are edited as temporary local copies and returned to the service when saved. Security features include password protection, encryption, permissions, digital signatures, digital IDs, and trusted certificates. Pro also supports PDF/A, PDF/X, and PDF/UA validation or conversion, plus accessible tagged PDF creation. The free PDF Studio Viewer can read and annotate PDFs and fill interactive forms. PDF Studio Pro costs $149, paid once for one user on two computers, with a perpetual license. The Unix installer does not include native OCR or scanning features.

Xodo Sign is an online service for signing, sending and managing documents through PDF editing and e-signature workflows. Users can prepare documents by adding signer and form fields, create reusable templates, set sequential signing order, send reminders and track document status. Completed signatures include a tamper-evident audit trail with signer activity, timestamps and IP addresses. The service runs on the web, iOS and Android, and the Xodo app supports reviewing, signing and sending documents on mobile. Named integrations include Google Docs, Zoho, Dropbox, Salesforce, Zapier and Gmail. Developers can use a JSON-based REST API, webhooks and embedded signing. Listed security and compliance capabilities include eIDAS, U.S. ESIGN, GDPR and SOC 2 Type 2. The Free plan is listed at free and allows up to 3 documents per month; a separate feature-page FAQ says 5 documents per month.
