XLS to PDF Converter Free — Convert Excel (.xls) to PDF Online

Need to convert an old .xls spreadsheet to PDF without buying Excel or uploading sensitive data to a stranger's server? Here's the 30-second method — and an honest account of what does and doesn't survive the trip.

Written and fact-checked by the Convertify editorial team. We test every workflow on real documents (government forms, design exports, scanned IDs, source code) before publishing — and re-test on each review date to keep the steps current.

The 30-Second Method

The fastest way is a browser-based converter — no Excel install, no upload to a server.

  1. Open Convertify's Excel to PDF converter.
  2. Drag your .xls (or .xlsx) file into the upload area, or tap to pick it from your device.
  3. Pick which sheet to convert — a preview of the first ten rows appears so you can check you got the right tab.
  4. Click Convert. Your PDF downloads in seconds.

What you get is a values export: your cell data laid out as a clean table across paginated pages, with the first row bolded as a header. It is not a picture of your spreadsheet — read the next section before you rely on it for anything with charts or heavy formatting.

Why Convert XLS to PDF?

Excel files are great for working — bad for sending. Common reasons people convert XLS to PDF:

  • Email-safe sharing. Many email clients block or strip macros from .xls attachments. PDFs always go through.
  • Portal uploads. Government forms, bank portals, school admission systems, and tax filings rarely accept .xls — but always accept PDF.
  • Layout integrity. Open the same .xls in Excel, LibreOffice, and Google Sheets and you'll see three slightly different layouts. PDF freezes the layout exactly as you intended.
  • Read-only sharing. A PDF can't be accidentally edited the way an .xls can.
  • Print-ready output. Excel's page breaks are notoriously fragile. A converted PDF prints predictably.
  • Long-term archiving. Decades from now, .xls might be hard to open. PDFs (especially PDF/A) are designed to last.

XLS vs XLSX: What Actually Changes in the Conversion

If you're converting an .xls file, you're probably working with a spreadsheet from before Excel 2007. Two practical differences:

  • .xls files have a 65,536-row limit per sheet (XLSX raised that to 1,048,576). If your XLS hits that limit, the PDF will too.
  • .xls macros (.xlsm equivalents) won't run during PDF conversion. Their last-saved output values are converted, but no fresh recalculation happens.

Other than that, Convertify reads both formats the same way.

What Survives the Conversion (and What Doesn't)

Most guides on this topic are vague here, so let's be specific. Convertify reads the values out of your sheet and draws them as a table. That means:

What comes through:

  • Cell values, in their original rows and columns, on paginated pages.
  • Formula results. A cell showing =SUM(B2:B10) in Excel appears as 1247 in the PDF. The formula itself isn't stored.
  • The header row, bolded on a tinted band so the table is readable.

What does not come through:

  • Charts and images. Bar, line, pie, pivot charts — none of them are drawn. If your sheet is mostly charts, this is the wrong tool.
  • Cell formatting — fills, borders, font families, conditional formatting colours, merged cells and number formats (a currency-formatted cell exports as the raw number).
  • Hyperlinks. The link text appears; it isn't clickable.
  • Comments and cell notes.

There are also two hard limits worth knowing before you convert: only the first seven columns fit the page layout, and each cell is truncated at 20 characters so the columns stay aligned. Wide sheets and long text cells will get clipped.

If you need a PDF that looks like your spreadsheet rather than one that carries its data, use Excel's own File → Export → Create PDF, or Google Sheets' File → Download → PDF. Both reproduce the visual layout properly. Convertify's value here is that it's free, needs no software, and never sends your figures to a server.

Converting XLS to PDF on iPhone & Android

iOS doesn't come with anything that opens .xls files, and the "Files → share as PDF" trick only works for files iOS can already preview. Use Convertify in Safari (iOS) or Chrome (Android) — same three-step flow as desktop. The converted PDF saves to your phone's Files / Downloads folder.

This is also the only way to convert .xls to PDF on phones without installing the heavy Microsoft Excel app.

Troubleshooting

Columns on the right are missing

The layout fits seven columns per page and drops anything beyond that. Reorder your sheet so the columns that matter come first, or split a wide sheet into two narrower ones and convert each, then join them with Merge PDF.

Cell text is cut off partway through

Each cell is truncated at 20 characters. Long descriptions, pasted URLs and free-text notes will be clipped. Shorten those values in the spreadsheet before converting, or move the long-text column out into its own document.

Only one sheet came out

That's by design — one sheet per conversion. Convert each tab in turn, then combine the resulting PDFs with Merge PDF.

My charts and colours are gone

Expected — this is a values-only export. For a visually faithful PDF, use Excel's File → Export → Create PDF or Google Sheets' File → Download → PDF.

PDF is too large to email

Run it through our PDF compressor with the "Medium" setting. Most spreadsheet PDFs compress 60–80% with no visible quality change.

Frequently Asked Questions

Frequently Asked Questions about XLS to PDF Conversion

How do I convert XLS to PDF for free?

Open Convertify's Excel to PDF converter, drop your .xls file in, pick the sheet you want, and click Convert. The PDF downloads instantly — no sign-up, no watermark, no Microsoft Excel needed. The file stays in your browser.

What's the difference between XLS and XLSX?

XLS is the older binary Excel format used in Excel 97 through 2003. XLSX is the modern XML-based format introduced in Excel 2007. They look identical to a human, but XLSX is smaller and more reliable. Convertify reads both.

Will my charts and formatting survive the conversion?

No. This is a values-only export: the converter reads the cell values and lays them out as a plain table. Charts, images, cell colours, borders, merged cells and number formatting are not carried over. Formulas are exported as the value they currently show, not as the formula. If you need a visually faithful PDF, use Excel's own File → Export → Create PDF.

Do I need Microsoft Excel installed to convert XLS to PDF?

No. Convertify works entirely in your browser — it reads both .xls and .xlsx without any Microsoft software. Works on Windows, Mac, Linux, iPhone, and Android.

Is it safe to convert sensitive financial XLS files?

Yes. Convertify processes the file 100% in your browser. There is no server upload — you can verify in your browser's DevTools Network tab. Safe for invoices, bank reports, financial models, and confidential spreadsheets.

Can I convert multiple sheets or multiple XLS files at once?

One sheet per conversion. Pick a sheet, convert, then repeat for the next one. To end up with a single document, convert each sheet in turn and combine the PDFs with our Merge PDF tool.

Why are some of my columns missing from the PDF?

The page layout fits seven columns. Anything past the seventh column isn't drawn, and each cell is truncated at 20 characters so the columns stay aligned. Trim or reorder your columns before converting if that clips something important.

Can I convert .xls to PDF on my phone?

Yes. Open Convertify's converter in Chrome on Android or Safari on iPhone. Tap the upload area, pick the .xls file from your phone or cloud storage, and the PDF downloads back to your phone — no app install needed.
