A finalized Excel financial report needs distribution to stakeholders. Sending the XLSX risks formula tampering or accidental edits. Sending a PDF preserves the formatting and locks in the values. PDFKits Excel to PDF converts XLSX or XLS files to standard PDF in your browser. Free, no signup, no upload, no installation of Microsoft Office.
The tool renders each worksheet as one or more PDF pages, preserving cell formatting (fonts, colors, borders, alignment), column widths, embedded images, and table headers. Multi-sheet workbooks become multi-page PDFs with sheet name printed at the top of each section. Page breaks set in Excel are respected. The output PDF opens in any viewer with formatting identical to Excel's print preview.
Drop your XLSX or XLS file into the tool. PDFKits parses the workbook with SheetJS and renders a preview of each sheet.
Pick page size (A4 default, Letter, Legal, A3 supported), orientation (portrait or landscape), and fit-to-page or actual-size. Choose whether to include sheet names as headers and whether to fit each sheet to a single page or allow multi-page sheets.
Click Convert. PDFKits renders each sheet as HTML via SheetJS, then captures the rendering with html2canvas, then assembles into PDF via pdf-lib. The resulting PDF downloads directly. A 5-sheet workbook converts in under 10 seconds.
Final quarterly reports go to investors as PDFs to lock in values and prevent accidental edits in transit. Excel sources stay internal.
Budget spreadsheets become PDFs for inclusion in proposal binders or client deliverables — same content, controlled format.
Spreadsheets archived for regulatory compliance need a stable format. PDF archival is more reliable than XLSX, which has format version drift between Excel releases.
Some workplaces require PDFs for printing approval workflows. Excel to PDF produces a deterministic print-ready file.
Microsoft Excel can export to PDF directly but requires the desktop app. Google Sheets export works but uploads to Google Drive. Online conversion services typically upload your file. PDFKits Excel to PDF runs in your browser using SheetJS + html2canvas + pdf-lib. Free, no signup, your spreadsheet data stays on your device.
PDFs don't carry formulas — only the computed values are shown. The PDF reflects the spreadsheet's current state at conversion time.
Yes — fonts, colors, borders, alignment, number formats (currency, percentage, date) all transfer to the PDF.
Yes. Images are rendered at their embedded resolution; charts are rasterized as part of the page rendering.
Yes. Multi-sheet workbooks produce multi-page PDFs by default, with sheet name as a header on each section.
Choose landscape orientation or enable 'fit to width' — PDFKits scales the sheet to fit.
SheetJS uses the cached values stored in the XLSX file (Excel writes computed values alongside formulas). Open the file in Excel/Sheets first to make sure values are up-to-date.
Currently no — remove password protection in Excel first, then convert.
