Frequently Asked Questions

How is text extracted from a PDF locally?
BigWow uses compiled PDF.js workers to load the document in-memory, traverse the PDF character map, and extract raw text characters. This occurs entirely in your browser window and is 100% private.
Is there a limit on how many images I can convert to a single PDF?
No. You can load dozens of local images (JPG, PNG, WebP) and compile them. The compiled document is generated directly using jsPDF, saving it straight to your Downloads directory.
