Privacy, compatibility and output quality
The supported processing for this tool runs locally in the browser. That means your selected PDF file stays on the device during the operation instead of being sent to Kaazo for server-side conversion. Browser-based processing can still be limited by your device's memory, browser capabilities and the complexity of the source file, especially with very large documents.
For important business, legal, financial or archival documents, keep the original and inspect the downloaded result carefully. Complex fonts, forms, layers, spreadsheet features, OCR text or unusual file structures may not reproduce exactly the same way as specialist desktop software.
