Does converting Excel to PDF require an internet connection?

Once the page loads, the entire conversion runs inside your browser. No files are uploaded to any server, so you can work offline after the initial page load.

Which Excel formats are supported?

Both .xlsx (Excel 2007 and later) and .xls (older Excel 97-2003) formats are supported. The tool reads the file directly in your browser using the SheetJS library.

Are merged cells preserved in the PDF?

Yes. The converter uses SheetJS to parse merged cell ranges and renders them as merged table cells with the correct colspan and rowspan values before capturing to PDF.

What about embedded images inside the spreadsheet?

Embedded images (PNG, JPEG, GIF, BMP, WebP) are extracted from the XLSX ZIP structure and injected into the correct cells before the PDF is rendered.

Can I convert all sheets at once?

Yes. When your workbook has multiple sheets, a "All sheets" option appears. Each sheet is rendered as one or more PDF pages depending on its size.

How does the page orientation option work?

Landscape (297 × 210 mm) works best for wide spreadsheets. Portrait (210 × 297 mm) is better for tall, narrow data. The content is automatically scaled to fit within the selected page size.

Is there a file size limit?

There is no enforced limit, but very large files may be slow to process because the rendering happens on your device. Files up to 50 MB typically work well on modern computers.

Does the PDF contain selectable text?

The PDF is image-based: each sheet is rendered as a high-resolution canvas image and embedded in the PDF. Text is not selectable, but the visual layout is pixel-accurate.

Will cell background colors and borders appear in the PDF?

Borders and text are preserved. Cell background colors depend on how the spreadsheet styles are written: standard solid fills are captured via the canvas render.

What happens if my spreadsheet is very wide?

Wide sheets are scaled down to fit the page width. For very wide sheets, switching to landscape orientation gives more horizontal space and produces a more readable PDF.

How to convert Excel spreadsheets to PDF free in your browser

Converting Excel files to PDF usually means installing Acrobat, paying for a subscription, or uploading your data to a third-party server. AlteredIdea's Excel to PDF converter runs entirely in your browser: your spreadsheet never leaves your device. The tool reads your .xlsx or .xls file using SheetJS, renders each worksheet as an HTML table onto a canvas, and exports the result as a PDF using jsPDF.

Merged cells, column widths, and embedded images are all handled automatically. If your workbook has multiple sheets you can convert one at a time or all at once, with each sheet becoming its own set of PDF pages. Choose landscape orientation for wide data tables or portrait for taller content, and the tool scales your spreadsheet to fit the A4 page automatically.
