Smallpdf Alternative

Smallpdf is polished and popular, but it works by uploading your PDF to its servers, and the free tier is limited to a small number of daily tasks. File Converts does the same everyday PDF work in your browser — no upload, no sign-up, and no daily cap on the in-browser tools.

What Smallpdf is

Smallpdf is the other PDF specialist in this comparison and the most design-led of the group — a Swiss company that built its reputation on making PDF work feel unintimidating. It leans hard into workflow integration: Google Drive and Dropbox pickers, e-signature, and team accounts sit alongside the conversion tools.

Where Smallpdf wins

Integration and signing. If your documents already live in Google Drive and need signatures with an audit trail, Smallpdf closes that whole loop in one place. We convert files and stop there.

The actual trade-off

Cloud integration is inherently a cloud capability. Pulling a file from Drive, signing it, and recording who signed and when requires the document to pass through their servers — that is the requirement, not an oversight. Our privacy guarantee and that feature set are mutually exclusive by construction.

Choose Smallpdf if

You need e-signature with an audit trail, or your document workflow is anchored in Google Drive or Dropbox.

Choose File Converts if

The document should not leave your machine, or you need formats well beyond PDF.

Frequently asked questions

Yes — especially if privacy or speed matter. File Converts converts files directly in your browser, so they're never uploaded, there's no upload wait, and the in-browser tools are free and unlimited. Smallpdf processes files on its servers, which is better suited to very large files or niche server-only formats.

In-browser conversions (most PDF, image, and document tools, plus OCR) are free and unlimited with no sign-up. A Pro plan adds large files, the API, and server-powered conversions.

Not for in-browser conversions — they run on your device and a live panel shows 0 bytes uploaded. A few advanced conversions (e.g. PDF → Excel) run on the server and are clearly labeled.

No. The in-browser tools work immediately with no sign-up and no email — unlike most cloud converters, which gate the free tier behind an account.

No daily limit on the in-browser tools. Because the conversion runs on your own device rather than on our servers, there's no per-user cost to meter — which is exactly why Smallpdf and similar services have to cap their free tier.

Yes. Once the page has loaded, in-browser conversions keep working with no connection — you can turn off your Wi-Fi and convert. A server-based converter like Smallpdf cannot do this by design.

Being honest: if you need very large files processed, a long tail of niche or exotic formats, or heavy batch automation on their infrastructure, a server-side service like Smallpdf is the right tool. File Converts is built for the everyday PDF, image, document, audio and video jobs — done privately and instantly.

No. We can password-protect and watermark a PDF, but we do not offer e-signature, and we are unlikely to: a signature is only worth anything if there is a verifiable record of who applied it and when, and that record has to live on a server. If you need signing, Smallpdf or Adobe Acrobat are the right tools.

Cloud import is available and off by default — it only appears once configured, because connecting it necessarily means a file travels over the network. Local files stay entirely on your device, and the privacy panel shows a live count of bytes uploaded so you can see the difference for yourself.
