XLS to PDF Converter

Turn XLS files into PDF in a couple of clicks. XLS is Excel's pre-2007 binary workbook; PDF is a fixed-layout document format that looks identical everywhere. Content is preserved and the layout is rebuilt for the target format.

How to use it

  1. 1

    Add your XLS files

    Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.

  2. 2

    Adjust the settings if you want to

    The defaults suit most people. Open Advanced to control page size, typeface and margins and delimiter and header handling.

  3. 3

    Convert and download

    Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your XLS file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your XLS file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

A spreadsheet is rarely about one person. It is usually about hundreds of them, which is what turns an ordinary file into a reportable data breach. It matters more than it sounds, because of what spreadsheets usually are:

Donor and volunteer databases

people who trusted an organisation, not a converter

Payroll

every colleague's salary, in one file

Customer and member lists

names, emails, phone numbers, addresses

Patient or client records

regulated personal data under HIPAA, GDPR and similar

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

XLS and PDF explained

The pre-2007 Excel format is a binary structure limited to 65,536 rows and 256 columns — limits modern datasets routinely exceed.

PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.

Where XLS files come from
Spreadsheets from Excel 2003 or earlier, and some legacy export systems.
Where PDF is used
Contracts, invoices, reports, forms, academic papers and scanned documents.

XLS vs PDF

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

Why convert XLS to PDF?

People make this switch when they run into the limits of XLS: anything else — XLSX is better in every respect. PDF is the better fit when sharing a finished document where the layout must not move.

XLS limitations that prompt the switch
Hard row and column limits. Larger files than XLSX. Binary format that is awkward to parse.
What you give up
Genuinely hard to edit — it stores positioned glyphs, not paragraphs. Scanned PDFs contain no text at all until OCR is run.

What is preserved when converting XLS to PDF?

The content survives; the layout is rebuilt. Text and the order it is read in carry across, but PDF lays the page out again rather than reproducing XLS's exact positioning, so line breaks, page breaks and spacing will differ. Anything that depends on precise placement is worth checking in the result.

XLS to PDF Converter — questions

How do I convert XLS to PDF?

Drop your XLS file onto the area above, then press Convert. The PDF file saves straight to your device. You do not need an account, and there is no watermark.

Is it safe to convert XLS files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your XLS file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential XLS files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

What should I know before converting XLS to PDF?

The sheet is laid out as a paginated table. Very wide sheets are scaled down to fit the page width.

What is preserved when converting to PDF?

Text, structure and images carry over faithfully. Exact page layout does not, because PDF lays content out differently from XLS. Check headings, tables and page breaks in the result.

How large a file can I convert?

Up to 100 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android. Pick the file through your phone's file picker — Files on iOS, or Downloads on Android — including files stored in iCloud or Google Drive.
