About the project
PDF tools built around local processing
KissPDF is a browser-based PDF toolkit maintained as one focused project. Its purpose is simple: make common document tasks available without requiring users to send the selected PDF to a document-processing server.
Who creates and reviews the site
KissPDF pages and tools are written and technically reviewed by the project maintainers. Tool descriptions are checked against the implementation rather than generated from a generic feature template.
We do not claim qualifications, awards, customer counts, ratings, or external audits that have not been independently established. When the project has not completed a compatibility or security review, the site says so.
Why the project exists
Reduce unnecessary uploads
Invoices, contracts, IDs, reports, and personal records should not need to cross another document-processing server for a simple page operation.
Explain the trade-offs
PDF rewriting can affect signatures, forms, bookmarks, scripts, layers, and image quality. Each tool page documents the relevant behavior.
Keep tools focused
Each page is built around one practical task with explicit inputs, controls, outputs, and limitations.
Make claims testable
Automated tests reopen downloaded files and check properties such as page count, dimensions, ordering, encryption, and compression.
Editorial and correction policy
- Describe only features present in the current implementation.
- Distinguish measured test results from guarantees.
- State when an operation rasterizes, recompresses, encrypts, or rewrites a PDF.
- Update the visible review date when technical behavior or guidance changes.
- Remove absolute claims such as “works everywhere” when no complete test matrix exists.
Questions and corrections
If a tool behaves differently from its description, or you find an inaccurate claim, email [email protected]. Include the tool name, browser version, and a description of the result; do not send a sensitive document.
