CleverPDF or PDFGym: which free option fits?

Who should pick which

A student needs lecture-slides.pdf turned into a Word file for quoting in an essay. The document is public, the conversion is exotic, and nothing about it is sensitive. That errand belongs at CleverPDF: its catalog stretches from Office formats through iWork to ebooks, and the upload costs nothing that matters.

An HR officer needs the same kind of conversion on a salary review. Here the file itself is the problem, not the format. CleverPDF's privacy page states that uploaded and output files sit on its servers until thirty minutes after processing, with an instant delete link (checked 10 September 2026). Thirty minutes is an honest, published window, and for a salary review it is still thirty minutes too long. Salary reviews, patient files, and anything under NDA belong in a tool that never uploads, which is the PDFGym case or a desktop program.

The two side by side

Both are free, so money is not the axis. Judge them on where your document travels and how far each tool goes once it gets there.

Where CleverPDF wins clearly

Catalog breadth is the honest headline. Its front page advertises 44 powerful and permanently free online PDF tools (cleverpdf.com, Checked 2 November 2026), and the list earns the adjective: PDF to Word, Excel, PowerPoint, Images, Pages, Numbers, Keynote, EPUB, JPG, PNG, TIFF, and Mobi, the reverse direction for most of them, plus unlock, split, rotate, compress, encrypt, combine, watermark, page numbers, image extraction, reorder, and delete. Niche pairs like EPUB to Mobi or Mobi to PDF exist there and simply do not exist here.

If your document is public and your format pair is unusual, stop reading and use CleverPDF. Converting a personal ebook collection or a downloaded manual through its servers risks nothing, and no narrower tool set can match that range. The converter roundup compares the format-work options across vendors for exactly these errands.

Where the private tab earns its keep

PDFGym trades breadth for two things: a boundary you can state in one sentence, and depth on the jobs it does cover. Every tool runs inside the browser tab, so the privacy claim is structural, not a retention policy that could change. The only thing that leaves the tab is usage data: which tool ran, which action fired, whether it succeeded, and how often. Never the document bytes, file names, page text, metadata values, or anything typed into a field. How it works draws the boundary, and the privacy page shows the complete list.

Depth shows in the details. Page work drags thumbnails into order, drops the rest, splits the file, and reopens the result to check page count and selectable text before any download. Rotation and crop set page properties and a crop box the reader honors, without rewriting the page content underneath. Compression takes an exact byte target instead of a quality preset. None of that replaces 44 tools, but for the jobs it covers, the output is checked rather than hoped for.

How we checked this page

The CleverPDF tool count and catalog were read on cleverpdf.com on 2 November 2026. The server-processing and thirty-minute deletion statements come from its privacy page as read on 10 September 2026 and may have changed since. PDFGym behaviors were taken from the tool pages and code in this project, including the usage-data boundary on the privacy page. No conversion quality tests were run, because upload policy, not output quality, is what separates these two.
