CrazySmartPDF vs free online Excel-to-PDF converters

Short answer: free online converters like Smallpdf and iLovePDF are the easiest way to turn an Excel file into a PDF — nothing to install, works from any browser on any operating system, and free for occasional use. If you’re on a Mac or a phone, or you just need a quick one-off, they’re the sensible pick. Their trade-off is threefold: your file is uploaded to their servers, the conversion is one-shot (they render the workbook roughly as its page setup dictates, so a table that’s too wide for the page comes out clipped or shrunk the same way Excel would), and there’s no per-file layout intelligence or self-check. CrazySmartPDF works the opposite way — it re-lays-out each sheet locally and checks its own output — but it needs Excel on Windows, so on the cross-platform, no-install axis the online tools clearly win.

At a glance

	Free online converters (Smallpdf, iLovePDF, …)	CrazySmartPDF
Cost	Free tier available	Free
Install	None — runs in the browser	Add-in or desktop app; needs Excel 2016+ on Windows
Platform	Any OS, any browser, phones included	Windows + Excel only
Where your file goes	Uploaded to their servers to convert	Add-in & desktop app render locally; the web app (beta) uploads
Layout	One-shot conversion of the existing page setup	Automatic re-layout — wide tables fit, rows never split
Dropped content	No report of what didn’t fit	Flagged — reports the rows/columns it clamped
Self-check	None	Flags blank and clipped pages (flags, not auto-fix)
Many files	Some let you queue several, each converted the same one-shot way	Batch a folder with smart layout applied to every file, plus a run log

What the online converters are great at

Give them their due — they’re genuinely good tools:

Zero friction. No install, no account needed for a quick job, no admin rights. Open the page, drop the file, download the PDF.
Cross-platform. They run on Mac, Linux, Chromebooks and phones — anywhere CrazySmartPDF can’t go today.
Fast for one-offs. For a single file that already fits the page, they’re as quick as anything.

If that describes your job, an online converter is the right answer and CrazySmartPDF isn’t worth installing.

Where CrazySmartPDF is different

The gap shows up on the harder jobs — wide sheets, long sheets, and doing it repeatedly:

It re-lays-out instead of converting once. A one-shot converter prints your workbook roughly as its current page setup says; if a table is wider than the page, that width problem carries straight into the PDF. CrazySmartPDF rebuilds the pagination so columns fit and no row is split.
Batch with intelligence, not just a queue. Queuing ten files still runs ten one-shot conversions. CrazySmartPDF applies the smart layout to every workbook in a folder and hands back a run log plus a self-check report.
It stays on your machine. The Excel add-in and desktop app render locally and never modify your originals — which matters for confidential financials you’d rather not upload.

The honest limitations — on both sides

Two honest points, one each way:

On our side: CrazySmartPDF needs Microsoft Excel 2016+ on Windows. It is not cross-platform, and there’s no phone version. And our own web app is a beta that, like the online converters, renders on a hosted service — so if you use that surface, your file is uploaded too. The local guarantee applies to the add-in and desktop app, not the beta web app.
On their side: uploading is fine for most spreadsheets, but for data that must stay on-premises it can be a non-starter, and a one-shot conversion gives you no signal about what got clipped or dropped.

Which should you use?

Use an online converter when you’re not on Windows, when you can’t install anything, or for a quick one-off that already fits the page.
Use CrazySmartPDF when you’re on Windows with Excel, your exports keep coming out clipped or split, you’re processing many files, or the data shouldn’t leave your machine.
