What you can do with indox PDF tools

A PDF tool does one job on a PDF file: join several files into one, cut a file into parts, shrink its size, turn it into Word or an image, or add a signature. This page lists 85 of them, grouped by job, so you can find the one you need without knowing its name.

The tools work in your browser, with nothing to install. Pick a tool, add your file and download the result. The same page lists 14 more tools for images, video, audio and fonts.

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?

Guests get a lower limit, and signing in raises it. A paid plan does not change it. The upload box shows your limit before you add a file.

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 14 tools for images, video, audio and fonts, and the conversions catalog covers 5,963 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.

Do the tools change my original file?

No. Every tool gives you a new file to download. Your upload is never modified, and on the free tier it is deleted automatically within 24 hours.

Is redaction really permanent?

Yes. Redact removes the text and image data under the marked area, not just a black box on top, so the content cannot be recovered from the file you download.

Will compressing a PDF hurt its quality?

Compress PDF has quality presets. Lower settings shrink images harder, while text and vector content stay sharp.
