PDFSub is an online PDF and document-processing SaaS that focuses on “98+ tools + bank statement conversion + AI document tools + API.” It offers browser-based PDF editing, merging, compression, format conversion, OCR, signatures, and more for general users, while also providing developers with HTML/URL/template rendering APIs that can generate PDFs, images, plain text, and Markdown.
In terms of feature coverage, PDFSub has a fairly complete toolkit: PDFs can be merged, split, rotated, cropped, watermarked, have metadata edited, forms filled, e-signed, encrypted, and unlocked. Its conversion capabilities cover Word, Excel, PowerPoint, images, HTML, EPUB, OpenDocument, and more. The AI modules include OCR, summarization, translation, Chat with PDF, structured data extraction, and handwriting recognition. Financial use cases are its differentiator, with support for converting bank statements to Excel, CSV, JSON, OFX, QBO, QFX, and QIF, as well as analysis for invoices, receipts, and financial reports.
On the API side, v1 currently focuses on rendering HTML inputs. Endpoints include /v1/convert/pdf, image, text, and markdown, with support for URL, HTML, or template_id + Liquid variables. It provides 10 SDK/code examples, webhooks, delivery to S3/GCS/R2/Google Drive/Dropbox, and highlights migration compatibility with PDFShift. However, PDF operations, OCR, and AI APIs are still on the Phase 7 roadmap and are not part of the current API capabilities.
The tools subscription lists All-in-One at $20/month and includes a 7-day free trial. API billing is separate: starting at $9/month for 500 credits, $24/month for 2,500 credits, and $249/month for 100,000 credits, with higher tiers also available. 1 credit covers up to 5MB of output. Overage billing is supported, and annual billing offers a 16.67% discount. A credit card is required for the trial.
On security, the basic tools claim to process files in the browser, while AI/advanced tools use encrypted server-side processing with automatic deletion. The API supports IP whitelisting, scopes, HMAC webhooks, and brute-force lockout. For compliance, it is labeled HIPAA-ready, Business+ can provide a BAA, and SOC 2 is still in progress.
The strengths are broad tool coverage, strong financial document processing, developer-friendly API documentation and multilingual SDKs, and transparent pricing rules. The drawbacks are that the current API scope is relatively narrow, there is no self-hosting option, team collaboration and permission details are limited, and SOC 2 has not yet been completed. It is best suited to individuals and small teams needing lightweight online PDF tools, people organizing financial data, and developer teams that need HTML-to-PDF, screenshots, or Markdown generation.
The crawled text does not provide information on access from mainland China, RMB payments, or local nodes, so china_access can only be assessed as unknown. If access stability, invoicing, domestic payment methods, or cross-border data transfer are important, consider evaluating local alternatives such as Foxit and WPS PDF, or compare it internationally with options like PDFShift and Sejda.
