All processing happens in your browser. Your files never leave your device.
Completely Free
No registration, no limits, no hidden costs.
Useful browser tools
PDF tools, workflow editing, and visible source links stay available without account gates.
Practical document workflows, not just buttons
OpenToolsKit pairs browser-based PDF tools with clear guidance about inputs, outputs, privacy limits, and what to check before sharing a finished document. The goal is to help users choose the right tool, avoid common file mistakes, and verify results before a document leaves their device.
Choose by task
Use merge and organize tools when page order matters, conversion tools when a format needs to change, and security tools when access, metadata, or visible sensitive content needs review.
Process locally where applicable
Many workflows run in the browser using JavaScript, workers, and WebAssembly. The privacy pages explain the boundaries, and tool pages call out cases where output verification matters.
Review before sending
A successful export should still be opened and checked. Page order, readability, signatures, redactions, metadata, and password settings can all affect whether a PDF is ready to share.
Learn the safest path for common PDF jobs
These short guides explain practical choices, limits, and verification steps for the most common browser-based PDF workflows.
How to merge PDF files without losing page order
Merging PDFs is usually simple, but the final file is only useful if the page order, duplicate pages, and attachments are checked before export.
How to compress a PDF without losing readability
Compression should make a PDF easier to upload or share without making text, scans, signatures, or diagrams hard to read.
How to convert JPG images to one PDF
JPG to PDF conversion is most useful when several images need to become a single document for upload, review, or archiving.
How to sign a PDF online safely
A visible PDF signature is useful for many everyday forms, but important documents should be checked carefully and may require a certificate-based process.
