The details
Privacy: browser vs. server
Smallpdf is honest about how it works: your file uploads to its servers in Switzerland, gets processed, and is deleted shortly after. The company is GDPR-compliant and takes security seriously. But the upload still happens. Your document travels over the internet, lands on a third-party server, and is retained for some period of time. That creates a record — one that can be subpoenaed, subject to a data breach, or retained longer than advertised.
ConvertYard runs the conversion inside your browser via WebAssembly. The same C++ libraries (MuPDF, pdf-lib) run locally on your CPU. Open your browser DevTools → Network while converting — you'll see no file upload request, because there isn't one.
Pricing: free vs. freemium
Smallpdf's free tier limits you to 2 tasks per day. Hit that limit at 10am and you're done until tomorrow, or you upgrade to Pro at ~$12/month. ConvertYard has no tier system. There is no paid plan to upgrade to — every tool is free for every user, every time. The site is supported by minimal display ads below tools.
Batch conversion
Smallpdf free tier processes one file at a time and counts each conversion against your daily limit. ConvertYard processes 1,000+ files in a single drop. All outputs package into a ZIP. Progress is tracked per file. If you regularly work with more than one or two documents at a time, the difference is significant.
Where Smallpdf is genuinely better
Smallpdf's PDF editor has annotation tools, a form-filling interface, and e-signature support that ConvertYard doesn't have. Its Pro plan integrates with Dropbox, Google Drive, and OneDrive. It also has mobile apps for iOS and Android. If your workflow centers on PDF annotation, signing, or cloud storage integration, Smallpdf Pro is a reasonable choice.
Verdict
If privacy matters, or you work with sensitive documents, or you need batch conversion, or you just don't want to create an account for a tool you'll use once — ConvertYard. If you need PDF annotation, e-signatures, cloud storage sync, or mobile apps — Smallpdf Pro.
Common questions
Does Smallpdf upload my files?
Yes. Smallpdf processes files on its servers in Switzerland. The company is GDPR-compliant and deletes files after processing, but your file does travel to an external server. If you are working with sensitive documents — contracts, medical records, financial statements — that upload creates a record that Smallpdf controls, not you.
Can I use ConvertYard instead of Smallpdf for free?
Yes, completely. ConvertYard has no daily limit, no file size cap, no account requirement, and no paid tier. Every tool is free for everyone, forever. The only current limitation is format breadth — ConvertYard focuses on the most common formats rather than every edge case.
Is ConvertYard as good as Smallpdf for PDF tools?
For the core workflows — compress, merge, split, rotate, convert to Word/JPG/PNG, OCR — yes. ConvertYard covers all of them, free and without upload. Smallpdf has a more polished annotation and form-filling UI and a wider ecosystem of integrations. If you need deep PDF editing or a Dropbox integration, Smallpdf's Pro plan may be worth it.
What does "2 tasks per day" mean on Smallpdf free?
Smallpdf limits free users to 2 file conversions per day. A single merge, compress, or convert operation counts as one task. Once you hit 2, you have to wait until the next day or upgrade to Pro. ConvertYard has no such limit.
Which tool is better for sensitive documents?
ConvertYard, by design. Because all processing happens inside your browser via WebAssembly, your file bytes never reach any external server. There's nothing for ConvertYard to retain, subpoena, or breach. Smallpdf offers server-side security, but the upload still happens.
