In their own words
Adobe PDF Services API
Adobe PDF Services API is a cloud-deployed web API for creating, converting, and organizing documents. It accepts static or dynamic HTML, Microsoft Word, PowerPoint, Excel, text, images, ZIP files, and URLs as inputs. It can create PDFs, merge JSON data with Word templates to produce PDF or Word documents, apply conditional logic, and generate documents in bulk. PDF operations include conversion to supported Office formats and images, combining or splitting files, inserting, replacing, reordering, and rotating pages, plus OCR for scanned PDFs. Listed outputs are PDF and DOCX. API access is available, with integrations for Microsoft Power Automate, Workfront Fusion, and UiPath. Adobe lists SOC 2, ISO 27001, and GDPR compliance. Support includes community resources, tickets, and documentation. A free plan provides 500 document transactions monthly; paid plans require a custom sales quote and ETLA or VIP purchase.
Dropbox Sign
Dropbox Sign is an e-signature service for individuals and businesses managing online agreement workflows. It supports sending signature requests, tracking them, and sending reminders. Signatures are legally binding under the U.S. ESIGN Act of 2000, with the same legal standing as pen-and-paper signatures. Templates save prepared fields for documents sent repeatedly, and embedded signing lets signers complete the process within a website. The API uses OAuth 2.0 and has official SDKs for Python, Ruby, PHP, Java, NodeJS, and C#. It also offers an audit trail and identity verification; bulk sending is not available. Senders and signers can use 22 languages, with apps for iOS and Android as well as web and API access. Listed integrations include Google Workspace, Microsoft Word, Salesforce, HubSpot, Slack, and Zapier. Dropbox Sign states that it complies with SOC 2 Type II, ISO 27001, eIDAS, and GDPR, and encrypts documents at rest with AES 256-bit encryption. A free plan allows three signature requests per month. Paid plans start at $10.05 a month with annual billing, and a 30-day trial is listed.
