To convert text files to PDF, Nutrient Web SDK relies entirely on its own technology built from the ground up, and it doesn’t depend on third-party tools. For more information on the supported formats, see the [list of supported file types](https://www.nutrient.io/guides/web/about/file-type-support.md). [Try for Free](https://www.nutrient.io/sdk/web/getting-started.md) ## Converting text documents to PDFs after displaying To convert a text document to a PDF after displaying it in the Nutrient viewer, follow the steps below. 1. [Load the source text document](https://www.nutrient.io/guides/web/open-a-document.md) (optional). To load the document without a user interface visible to the user, use the `headless` parameter. 2. Make changes to the document (optional). For example, [add annotations](https://www.nutrient.io/guides/web/annotations/create-edit-and-remove/create.md). 3. Convert the source document to a PDF with the [`exportPDF`](https://www.nutrient.io/api/web/NutrientViewer.Instance.html#exportPDF) method (optional). Use the `outputFormat` flag to create a PDF/A document. For more information, see [converting PDF to PDF/A](https://www.nutrient.io/guides/web/conversion/to-pdfa.md). 4. Save the output document. The `exportPDF` method returns a `Promise` that resolves to an `ArrayBuffer` containing the output PDF document. You can use the resulting `ArrayBuffer` to download or persist the output PDF in storage. For more information on downloading or persisting the exported `ArrayBuffer`, see the [guides on saving a document](https://www.nutrient.io/guides/web/save-a-document.md). The following example loads a text document and exports it to a PDF: ```js NutrientViewer.load({ container: "#pspdfkit", document: "source.txt", licenseKey: "YOUR_LICENSE_KEY" }).then((instance) => { instance.exportPDF(); }); ``` The following example loads a text document, exports it to a PDF with conformance level PDF/A-4f, and downloads it in the client’s browser: ```js NutrientViewer.load({ container: "#pspdfkit", document: "source.txt", licenseKey: "YOUR_LICENSE_KEY" }).then((instance) => instance.exportPDF({ outputFormat: { conformance: NutrientViewer.Conformance.PDFA_4F } }) ).then(function (buffer) { const blob = new Blob([buffer], { type: "application/pdf" }); const objectUrl = window.URL.createObjectURL(blob); downloadPdf(objectUrl); window.URL.revokeObjectURL(objectUrl); }); function downloadPdf(blob) { const a = document.createElement("a"); a.href = blob; a.style.display = "none"; a.download = "output.pdf"; a.setAttribute("download", "output.pdf"); document.body.appendChild(a); a.click(); document.body.removeChild(a); } ``` When exporting a document, you have several options. Refer to our guides on [flattening annotations](https://www.nutrient.io/guides/web/annotations/flatten.md) and [incremental saving](https://www.nutrient.io/guides/web/features/document-processing.md) for more details. Auto saving can be configured for different scenarios and use cases. You can find more information in our [auto save](https://www.nutrient.io/guides/web/features/saving.md) guide. ## Converting text documents to PDFs without displaying To convert a text document to a PDF without displaying it in the Nutrient viewer, follow the steps below. 1. Load and convert the source text document using the [`convertToPDF`](https://www.nutrient.io/api/web/NutrientViewer.html#.convertToPDF) method. This method takes the following parameters: - A [`Configuration` object](https://www.nutrient.io/api/web/NutrientViewer.Configuration.html) that specifies the path to the source document and the license key. - A member of the `Conformance` enumeration that specifies the conformance level of the output PDF document (optional). If you provide this parameter, the output is a PDF/A document. 2. Save the output document. The `convertToPDF` method returns a `Promise` that resolves to an `ArrayBuffer` containing the output PDF document. You can use the resulting `ArrayBuffer` to download or persist the output PDF in storage. For more information on downloading or persisting the exported `ArrayBuffer`, see the [guides on saving a document](https://www.nutrient.io/guides/web/save-a-document.md). The following example exports the loaded document to a PDF with conformance level PDF/A-4f: ```js NutrientViewer.convertToPDF( { document: "source.txt", licenseKey: "YOUR_LICENSE_KEY" }, NutrientViewer.Conformance.PDFA_4F ); ``` The following example converts a text document to a PDF document and downloads it in the client’s browser: ```js NutrientViewer.convertToPDF({ document: "source.txt", licenseKey: "YOUR_LICENSE_KEY" }).then(function (buffer) { const blob = new Blob([buffer], { type: "application/pdf" }); const objectUrl = window.URL.createObjectURL(blob); downloadPdf(objectUrl); window.URL.revokeObjectURL(objectUrl); }); function downloadPdf(blob) { const a = document.createElement("a"); a.href = blob; a.style.display = "none"; a.download = "output.pdf"; a.setAttribute("download", "output.pdf"); document.body.appendChild(a); a.click(); document.body.removeChild(a); } ``` When exporting a document, you have several options.
