With most sites, the privacy policy is where they explain everything they collect. This one is short for the opposite reason: the converter runs on your device, so there isn't much for us to collect. Here's exactly what does and doesn't happen to your data.
1. The short version
We never receive your files. Every conversion happens locally, inside your web browser, on your own device. ZeroUpload does not operate servers that receive, process, or store the files you convert — because the conversion does not require one.
2. Your files
- When you convert a file, it is read into your browser's memory, converted on your device, and offered back to you as a download.
- Your file is never uploaded to ZeroUpload or any third party.
- We keep no copy of your files, ever. We could not retrieve one if asked — we never had it.
- When you close or refresh the page, the file data is released from memory.
You can verify this yourself: start a conversion and then disconnect your internet — it will still work — or open your browser's developer Network tab and confirm there are no upload requests. (The AI-powered background remover needs a one-time model download first; after that, it too does all its work on your device. See section 5.)
3. Information we do collect
ZeroUpload is a static website. To operate and improve it, we may use:
- Privacy-respecting, aggregate analytics to understand anonymous usage (such as which pages are popular and general traffic counts). This never includes the contents of your files and is not used to identify you.
- Advertising: If the site displays ads, our advertising partners may use cookies or similar technologies as described in their own privacy policies. You can control cookies through your browser settings. Ads never receive your files.
We do not require accounts, and we do not ask for or store personal information such as your name or email to use the converter.
4. Cookies
The core converter works without requiring cookies. Any cookies used are limited to basic site functionality and, where applicable, advertising partners. You can block or delete cookies in your browser settings at any time.
5. Third-party services
The site is hosted on a content delivery network (CDN) that serves the static pages and conversion engine files. Like all web hosts, the CDN may process standard technical request data (such as IP address and user agent) to deliver the site and protect against abuse. This is standard web infrastructure and does not involve your converted files.
AI-powered tools. The background remover runs an AI model directly in your browser. The first time you use it, your browser downloads the model file once from a third-party AI model host (Hugging Face's CDN); after that it is cached on your device. Downloading the model involves a normal web request to that host, but your image is still never uploaded — only the model comes down to your device, and all processing happens locally.
6. Children's privacy
ZeroUpload is a general-purpose utility and is not directed at children under 13. We do not knowingly collect personal information from children.
7. Your rights (GDPR / CCPA)
Because we do not collect or store your files or personal account data, there is nothing of yours for us to export or delete. For any questions about data the CDN or advertising partners may process, contact us and we will help where we can.
8. Changes to this policy
We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
