PDF tools questions
Are the PDF tools free?
Yes, to start. You get free credits every day with no account and no card. Tools marked Pro unlock with any paid plan, which also adds batch and priority processing.
Do I need to sign up or install anything?
No. The tools work in your browser, so there is nothing to install, and you can use them as a guest. Signing in raises your upload limit and keeps your history.
What happens to my files after I upload them?
Files are encrypted in transit. Files uploaded on the free tier are deleted automatically within 24 hours.
How large a PDF can I upload?
The limit depends on your plan. Signing in gives you a higher limit than a guest gets, and paid plans allow larger files.
Can I work with a scanned PDF?
Yes. OCR PDF turns a scan into searchable, selectable text, and AI Extract reads the layout of a scan or photo to pull out its fields and tables.
How do I find the right tool?
Type a job or a file type in the search box, for example merge, compress or DOCX. The bar under it shows how many tools match in each group and jumps to that group.
Does indox only work with PDF files?
No. This page also lists 38 tools for images, video, audio and fonts, and the conversions catalog covers 5,967 file conversions.
Can I run these tools from code?
Yes. One REST API runs every tool on this site: send a file, poll the job, download the result. The free tier needs no key.
