Questions & Answers

As answered by people managing Smallpdf and Kit-Bin.

What makes your product unique?

Kit-Bin's answer:

Kit-Bin's tools run entirely client-side, in the browser, using JavaScript/WASM — no file is ever transmitted to a server. That's a stronger claim than most "privacy-friendly" converters make, since it's an architectural fact you can verify yourself (open devtools, watch the Network tab while using any tool) rather than a retention policy you have to trust. It's also open source, no accounts, no signup, and no feature paywall — the entire 60+ tool suite (PDF, image, audio, video, data, and developer utilities) is free and usable immediately.

Why should a person choose your product over its competitors?

Kit-Bin's answer:

Most free converter sites — even ones that market themselves as privacy-conscious — still upload your file to a server to process it and rely on a policy promise ("we delete it after 24 hours") rather than a technical guarantee. Kit-Bin never uploads anything in the first place, so there's nothing to trust and nothing that can leak in a breach, because the file never leaves your device. For anyone converting or editing something sensitive — a scanned ID, a document with personal data, a photo with embedded location metadata — that's a meaningful difference, not a marketing detail. It's also genuinely free with no account wall, and open source, so the claim is checkable rather than taken on faith.

How would you describe the primary audience of your product?

Kit-Bin's answer:

Two overlapping groups: privacy-conscious individuals who specifically don't want to upload personal files to a third-party server (students, professionals handling sensitive documents, anyone converting photos or scans with personal data attached), and developers/technical users drawn to the developer-tool utilities (SHA-256, Base64, UUID generation, JSON schema validation, QR codes) who value the same no-upload guarantee for things like credentials, config files, or internal data.

What's the story behind your product?

Kit-Bin's answer:

It started from a personal frustration: needing to convert, merge, or clean a file — sometimes something sensitive, like a scanned document or a photo that still had GPS metadata embedded in it — and finding that every "free" tool available wanted it uploaded to a server first. Rather than trust a privacy policy, the goal became building tools that were private by construction instead of by promise. Once a couple of tools worked that way, the same principle applied naturally to every other file type people deal with regularly, which is how one converter grew into a full suite across PDF, image, audio, video, data, and developer tooling.

Which are the primary technologies used for building your product?

Kit-Bin's answer:

Client-side JavaScript/WebAssembly for the actual file processing (so tools run entirely in the browser), with Astro powering the site itself. Double-check this against your actual current stack before submitting — I'm working from what's visible in the codebase/site structure, not a confirmed tech-stack list, and don't want to state something that's since changed.
