About 100PDF
Purpose
100PDF is a focused PDF workspace for common document tasks that should not require an account or an upload queue. The service is built for people who need to finish a practical PDF job quickly while keeping supported files on their own device.
Tools available today
The current product includes PDF merge, split, compression, PDF to JPG, PDF to PNG, JPG to PDF, PNG to PDF, and password protection. Each tool has its own instructions, limits, and browser-local workflow rather than acting as a placeholder for an unavailable service.
Local processing model
Supported operations use client-side PDF libraries in the visitor's browser. Selected documents, filenames, page ranges, document contents, and passwords are not uploaded to a 100PDF server for core processing.
Quality and limits
100PDF verifies supported workflows and publishes the limits of each tool. Browser results can still vary with the source file, browser, and device, so downloaded documents should be reviewed before important use. OCR, document repair, redaction, Office conversion, and digital signing are not currently offered.
Free service and contact
100PDF is free to use without registration and may be funded by optional advertising. Advertising providers do not receive the PDF files used by browser-local tools. For product, privacy, policy, or site-owner questions, contact contact@100pdf.com.
