Good to know
Do I need to create an account?
No. Every tool works immediately, with no sign-up and no email required.
Are my files really private?
Yes for all PDF tools: they run 100% in your browser using open-source libraries (pdf-lib, pdf.js). Your files never leave your device. The Image to Prompt tool is the only exception — it sends your image to Google\u2019s Gemini API to generate the description.
Do the tools work on phones?
Yes. Every tool is mobile-friendly: you can pick files from your phone and download results directly.
Is there a file size limit?
PDF tools have no artificial limit, but very large files (hundreds of MB) can be slow on older phones. Image to Prompt accepts images up to 4 MB, with 10 free generations per day.
Can I use the results commercially?
Yes. PDFs you create and prompts generated for you are yours to use however you like.
