Privacy policy
The important part first: your video, sound, and pictures are never sent anywhere.
Last updated: September 13, 2026
Operator: MFP Inc.
1. How your video, sound, and pictures are handled
Everything SakuConvert does - converting, compressing, cropping and the rest - happens entirely inside your browser. Neither the file you choose nor the file you save is ever sent to a server. The file name is not sent either.
The proof is that it still works after you open the page and turn on airplane mode (Why it is safe to use).
While a file is being made, it may be kept in a temporary place inside your browser (on your own device). It is deleted when you start over, make the next file, or open the page again. The operator cannot see it.
2. Information sent to outside services
This site uses the three services below. None of them receive the contents of your video, sound, or pictures, or your file names. File names are never put in page titles or URLs either.
Delivering the site (Cloudflare)
The site is delivered from Cloudflare Pages. Because of how delivery works, information about the connection (such as your IP address) may remain in Cloudflare’s own records, but the operator does not use it to identify individuals.
Analytics (Cloudflare Web Analytics)
To learn how much the pages are viewed and whether they load quickly, we use Cloudflare Web Analytics.
- It does not use cookies or browser storage (such as localStorage).
- It does not tell individual people apart or follow them across other websites (according to Cloudflare).
- It collects things like the URL of the page you viewed, where you came from (the referrer), the type of browser and device, and how long the page took to show.
Ads (Google AdSense)
To pay for running the site, we show ads from Google AdSense (we will start showing them once Google’s review is finished).
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You can opt out of personalized advertising in Google’s Ads Settings. You can also opt out of some third-party vendors’ cookies at aboutads.info.
- To learn how Google uses this information, see How Google uses information from sites or apps that use our services.
If you are visiting from the European Economic Area (EEA), the United Kingdom, or Switzerland, Google’s consent management asks first whether advertising cookies may be used. If you do not agree, ads that do not use cookies to personalize them may still be shown.
3. Disclosure of information sent to outside parties (Japan’s Telecommunications Business Act)
When you open this site, your device sends information to the following recipients.
| Recipient | Information sent | Purpose |
|---|---|---|
| Cloudflare, Inc. (Cloudflare Web Analytics) | URL of the page viewed, referrer, type of browser and device, time taken to show the page | Counting page views and measuring loading speed |
| Google LLC (Google AdSense) | URL of the page viewed, browser and device information, IP address, cookie identifiers | Serving ads, measuring their results, preventing fraud |
| Google LLC (consent management; EEA, UK, and Switzerland only) | Your consent choices, browser and device information | Recording consent and choosing ads accordingly |
For how Google handles information, see Google’s Privacy Policy.

When we add or change a service, we will rewrite this page and update the “Last updated” date.
