Edit, sign, convert, combine and automate PDFs without leaving the browser. Change existing text, add text, pictures, shapes, comments and stamps; fill forms and sign; redact sensitive content for good; reorder, rotate, insert, extract, combine and split pages; convert PDF to Word and Word to PDF, PDF to Excel, images and text; OCR scanned drawings and reports into searchable PDFs or editable Word files; add watermarks, headers and footers, page numbers and Bates numbers; compress for email; and run batch actions over a whole folder of files.
Your files never leave this device — every step runs in the browser. The PDF, OCR and conversion engines (pdf.js, pdf-lib and Tesseract) load from public CDNs the first time you use them. Conversions rebuild documents and may not keep every detail of complex layouts; check important documents before sending them.
What the PDF studio does
Open a PDF, a Word document, a text file or images and work on them like in a desktop PDF editor. Edit existing text in place (the old line is covered and replaced in a matching font), add text boxes, pictures, shapes, arrows and freehand drawing, white out content, add sticky-note comments, highlights, underlines, strikethroughs and review stamps, fill in form fields, sign with a drawn, typed or scanned signature, and redact by hand or by searching for words, emails, phone numbers and amounts — redacted pages are rebuilt so the hidden text is gone for good.
Organise pages with drag-and-drop thumbnails: reorder, rotate, delete, duplicate, insert blank pages or other files, extract and reverse. Combine any mix of PDFs, Word files and images into one PDF with bookmarks, and split by every N pages or custom ranges. Convert PDF to Word (headings, paragraphs, lists and tables, with snapshots of drawings), Word to PDF, PDF to Excel, images and text, and images or text to PDF. Recognise text in scans with OCR in a dozen languages to make a searchable PDF, a Word file or plain text. Finish documents with watermarks, headers and footers, page numbers and Bates numbers, edit or strip metadata, compress for email, and automate it all with the action wizard: chain steps and run them over many files at once. Everything is processed on your own device; nothing is uploaded.
