// Features
Every PDF task. One tool.
EJoyPDF is the last PDF tool you'll need. Edit text in-place, watermark any page range, split 500 pages into chapters, sign with a legal X.509 certificate — all offline, all yours.
Rich Text Editing
Edit any text, image, or vector element directly on the PDF
canvas. Reflow paragraphs,
change fonts, swap images — all in-place, no re-export needed.
Watermark Studio
Add text or image watermarks to any page range — opacity, angle,
position, colour.
One-click removal of existing watermarks via content-stream analysis.
Split & Merge
Extract any page range, reorder with drag-and-drop, merge
unlimited PDFs, and interleave
pages from multiple documents in one operation.
Form Fields & Signing
Create, fill, and flatten AcroForm fields. Add legally-binding
digital signatures with
X.509 chains. Timestamp via RFC 3161 TSA for long-term validation.
OCR & Text Recognition
90-language Tesseract OCR with layout-preserving output. Convert
scanned PDFs to fully
searchable text — paragraph by paragraph, preserving tables and columns.
Batch Processing
Apply any action — watermark, compress, sign, OCR, split — to
hundreds of PDFs in one
queue. Scriptable via CLI with JSON templates for CI/CD pipelines.
// Watermark Studio
Add it. Strip it. Your document.
Text, image, QR code — any angle, any opacity, any page range. One-click removal analyses the content stream and surgically extracts existing watermarks without touching a single line of text.
