Free online tools, without an account

GOATiM provides free access to 49 browser tools for video, audio, photos, PDFs, archives, text, data and developer tasks. Open a tool and get started without logging in, registering or buying a subscription.

Which tools process my files on my device?

The online video editor, video and audio converter, bulk photo resizer, PDF toolkit and signature upload, text compare and diff checker, and ZIP, TAR and GZIP archive tool process your inputs in your browser, without sending them to a processing server.

Does PDF signature upload send my signature to a server?

No. Choose a signature image from your device or draw one, then place it on PDF pages in the browser. You can save up to five signatures in this browser for reuse and delete them later.

Do these tools work without an internet connection?

Local processing does not mean every tool is available offline. Pages, 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 the memory your browser can use.
