PDFKit
AI-powered PDF tools for processing, conversion, and editing
Open PDFKitWhat it does
PDFKit brings together a wide range of PDF operations into a single, browser-friendly workspace. You can compress large files to a manageable size, merge multiple documents into one, split a large PDF into individual pages, convert between PDF and popular formats like Word, Excel, PowerPoint, and images, run OCR on scanned documents to make them searchable, add or remove watermarks, and apply digital signatures. On the AI side, PDFKit can summarize long documents, answer questions about their contents, translate text between languages, and extract structured data such as tables, key-value pairs, and form fields.
Who it is for
PDFKit is designed for office workers, students, freelancers, marketers, legal professionals, accountants, and anyone who regularly handles PDF documents. It is equally useful for small teams that need to process documents without investing in expensive desktop software, and for developers who want to automate document workflows or extract structured data from PDFs.
Main features
Compress & Optimize
Reduce PDF file size without visible quality loss by removing redundant objects, downsampling images, and stripping unused metadata.
Merge & Split
Combine multiple PDFs into a single document or split a large file into individual pages or page ranges.
Convert Formats
Convert between PDF and Word, Excel, PowerPoint, images, and other common formats while preserving layout and formatting.
OCR Recognition
Turn scanned, image-based PDFs into searchable, selectable text using optical character recognition.
Sign & Watermark
Apply digital signatures, stamps, and watermarks to protect and authenticate documents.
AI Chat & Summarize
Ask questions about a document, generate summaries, translate content, and extract structured data using AI.
Privacy notes
Many PDFKit operations run client-side in the browser, meaning your files do not need to be uploaded to a server for basic processing. Some features, such as OCR on large documents, AI summarization, translation, and certain format conversions, may require server-side processing or external AI services. When server processing is used, files are processed for the duration of the operation and are not retained unless you explicitly save them to your account.
