How these tools work

OpenToolKit focuses on useful browser-based utilities. Individual pages explain what a tool does, how to use it, and its limits. Most current text and data processing happens locally in your browser.

We only list tools that are already available. PDF tools are available now. New image-processing categories will only be listed once tested.

How to choose a tool

Start with the task rather than the file type alone. For example, merge PDF combines complete documents, while split PDF selects specific pages. JSON Formatter validates syntax; JSON Compare identifies changed parsed values. Each tool page includes a realistic example and describes what the output can and cannot preserve.

For step-by-step explanations, see the OpenToolKit guides. We do not promise perfect conversion for encrypted, damaged or complex documents.

Choose the right PDF operation

Merge joins files in their original page sequences. Split keeps selected pages; Remove discards selected pages. Reorder rearranges the complete page set. Rotate changes display orientation, while Images to PDF makes pages from individual pictures. Use non-sensitive test documents first and check your output.

For step-by-step examples, consult our practical guides and test the output before using it in important work.
