DocHub vs PDF.co

DocHub is a browser-based PDF editor and e-signature app. Chris Devor, who earlier built the iPhone utility maker Macroplant, launched it in October 2014, and it grew mainly through its Google Workspace Marketplace add-on, which has passed 57 million installs. In July 2022 airSlate acquired DocHub. Its core job is to open a PDF from Drive, Gmail or your computer, edit or fill it, sign it and send it out without installing desktop software.

The editor handles text edits, highlights, drawings, comments, page reordering, merging and splitting. Documents can go to several signers in a set order, with templates and an audit trail. Files can be opened from Google Drive, Gmail and Google Classroom as well as Dropbox, Box and OneDrive. The free plan shares three uses per month across core features; Basic and Pro are low-cost per-user subscriptions, and a Site License covers whole schools or companies.

DocHub fits teachers, freelancers and small teams living in Google Workspace who sign and annotate documents occasionally. It is not a full replacement for Adobe Acrobat when you need advanced PDF production or desktop editing, and its signing workflows are lighter than dedicated e-sign suites. pdfFiller has a bigger form library and signNow focuses on high-volume e-sign workflows and APIs, both from the same parent company.

Buying tip: prices are localised, so European visitors see euros instead of dollars, and annual billing cuts about 25%. Because airSlate owns three overlapping products, compare limits across DocHub, pdfFiller and signNow before you commit.

PDF.co is a cloud API and no-code service for working with PDF and document files. Developers call its REST endpoints, and automation builders use its ready-made modules in Zapier, Make, n8n and Power Automate, to extract data, convert formats, generate documents and manipulate PDFs without running their own PDF libraries or servers.

Extraction features turn PDF tables into CSV, JSON, XML or Excel, pull text with positional information and parse invoices, receipts and other documents with templates or AI-based parsing. Generation endpoints create PDFs from HTML, URLs or templates, which suits invoices, certificates and reports. Manipulation tools merge, split, compress, rotate, password-protect, add text, images or signatures, fill form fields and read or generate barcodes and QR codes. Pricing is credit-based: monthly plans include a credit allowance, each operation consumes credits depending on pages and complexity, and pay-as-you-go top-ups are available.

PDF.co fits developers and operations teams automating repetitive document work, such as pulling invoice data into a spreadsheet or generating hundreds of PDFs from form submissions. Credit consumption can be hard to predict, template-based parsing needs setup per layout, and accuracy depends on scan quality. Adobe PDF Services API is the enterprise-grade alternative, DocRaptor and PDFMonkey focus on generation from HTML, and Nanonets or Docparser are stronger for high-volume document data extraction.

For teams that need many PDF operations behind one API key, it is a flexible and inexpensive starting point.
