A few useful details

Access, privacy and browser requirements.

Are all these tools free to use?

Yes. All 58 tools are free and ad-free. You can get started without an account, registration or subscription.

Which tools process my files on my device?

The video editor, media converter, photo resizer, PDF toolkit, text comparison tool and archive tool process your inputs in your browser without sending them to a processing server. Each tool explains its processing behavior.

Does adding a PDF signature upload it to a server?

No. Signature images and drawn signatures are placed on the PDF in your browser. You can save up to five signatures in this browser for reuse and delete them later.

Will video or photo exports have a watermark?

The video editor and photo album creator export your work without adding a GOATiM watermark.

Do the tools work offline?

Local processing does not mean every tool works offline. Pages, scripts, fonts and processing engines may need to download first. PlantUML preview sends diagram source to an external renderer, and HTML previews or linked images can request external resources.

Is there a file size limit?

Practical limits depend on the tool, file format, browser and available device memory. Large video conversions and archives may take longer or exceed your browser's available memory.
