HummingBird PDF
Complete PDF Toolkit
End-to-end PDF toolkit providing comprehensive editing, merging, OCR, read-aloud, citation finder, and translation features.
Key Features
One platform covers the complete PDF workflow: merge, split, compress, rotate, crop, redact, watermark, e-sign, convert to/from Word and PowerPoint, OCR scan-to-text, HTML-to-PDF, and more. No need to maintain subscriptions to multiple single-purpose tools — everything lives under one roof.
All uploads travel over TLS and files are encrypted at rest during processing. Processed documents are permanently deleted from servers immediately after the task completes — typically within minutes. No document content is stored, indexed, or used for any purpose beyond completing your requested operation.
The optical character recognition engine achieves over 95% character accuracy on standard scanned documents, with an AI post-processing pass that corrects common OCR artefacts (confused characters, hyphenation errors, garbled tables) before delivering the extracted text or searchable PDF.
Trusted by over 2.5 million users worldwide for document workflows ranging from academic citation finding and multi-language translation to read-aloud accessibility playback. The scale of the user base drives continuous improvement to tool reliability, format compatibility, and processing speed.
