+# convert-all-pdf.sh
+
+With version 0.9.0 there was support added for another external tool,
+[OCRMyPdf](https://github.com/jbarlow83/OCRmyPDF), that can convert
+PDF files such that they contain the OCR-ed text layer. This tool is
+optional and can be disabled.
+
+In order to convert all previously processed files with this tool,
+there is an
+[endpoint](/openapi/docspell-openapi.html#api-Item-secItemConvertallpdfsPost)
+that submits a task to convert all PDF files not already converted for
+your collective.
+
+There is no UI part to trigger this route, so you need to use curl or
+the script `convert-all-pdfs.sh` in the `tools/` directory.
+
+
+# Usage
+
+```
+./convert-all-pdfs.sh [docspell-base-url]
+```
+
+For example, if docspell is at `http://localhost:7880`:
+
+```
+./convert-all-pdfs.sh http://localhost:7880
+```
+
+The script asks for your account name and password. It then logs in
+and triggers the said endpoint. After this you should see a few tasks
+running.
+
+There will be one task per file to convert. All these tasks are
+submitted with a low priority. So files uploaded through the webapp or
+a [source](@/docs/webapp/uploading.md#anonymous-upload) with a high
+priority, will be preferred as [configured in the job
+executor](@/docs/joex/_index.md#scheduler-config). This is to not
+disturb normal processing when many conversion tasks are being
+executed.
