A Private Alternative to Smallpdf & iLovePDF

Updated June 2026 · 5 min read

Smallpdf and iLovePDF are genuinely useful - but they share one design choice worth thinking about: your files are uploaded to their servers to be processed. For a meme, who cares. For a signed contract, a bank statement or a medical report, that is a different conversation. This is a look at how to do the same PDF jobs without anything leaving your computer.

The upload model vs the in-browser model

Traditional online PDF tools work server-side: you upload, they process, you download, and they promise to delete your file "within an hour." You are trusting that promise. Modern browsers are powerful enough to do most of that work locally - with JavaScript and WebAssembly - so the file never travels anywhere. OpenConvert is built entirely on this in-browser model: no accounts, no uploads, no "trust us."

The same jobs, done privately

Here is how the common Smallpdf / iLovePDF features map to private, in-browser tools:

• Compress PDF - shrink scans and reports with the PDF compressor.
• Merge PDF - combine files in any order with Merge PDF.
• Split PDF - pull out pages or ranges with Split PDF.
• PDF to JPG - export pages as images with PDF to JPG.
• PDF to Word - get an editable DOCX, even from scans, with PDF to Word (OCR).
• JPG to PDF - build a PDF from images with Images to PDF.
• Rotate PDF - fix sideways pages with Rotate PDF.

🔒 Browse all the private PDF tools
Compress, merge, split, rotate and convert - every tool runs in your browser, free, with no upload.

What you gain - and the trade-offs

You gain: real privacy (files stay local), speed (no upload/download round-trip), no sign-up, and no per-day limits. The trade-offs: very large files are limited by your device's memory rather than a big server, and a few heavyweight features (like pixel-perfect PDF-to-Word layout reconstruction) are still better on the desktop. For the everyday 90% - compress, merge, split, convert - in-browser is faster and safer.

When server tools still make sense

If you are collaborating on a shared link, need cloud storage integration, or are processing hundreds of huge files in a pipeline, a server product earns its keep. For one-off, sensitive, or personal documents, a private in-browser tool is the better default.
