Your files stay
with you.
Updated October 1, 2026. The site is hosted on Railway. A contact address for the operator is not yet published here.
Files and text
Image conversion, PDF assembly and compression, text formatting, and color calculations run on your device. The application does not upload the selected files, filenames, pasted text, or generated results to a conversion server.
Your working input stays in page memory. “Continue with…” buttons deliberately pass selected results to another tool in the same tab. This is temporary: refreshing or closing the tab discards that workspace. Downloads remain on your device until you delete them.
Camera and microphone
Device access begins only after you start a test and your browser grants permission. Camera previews, microphone meters, and optional short audio or video recordings remain local. Camera microphone audio is off by default; enabling it requests microphone access when you start the camera. Stop ends all media tracks owned by this page. A completed sample stays in page memory until you delete it, start another test or recording, or leave the page. Downloaded samples remain on your device. Other tabs or applications may still use the same device.
Keyboard input
The keyboard tester listens only while its test area has focus. It does not install a sitewide keystroke listener or send key events to a server. Moving focus out ends the active test.
Website requests
Loading any website sends network information, including your IP address and requested URL, to its hosting infrastructure. This differs from uploading the content you process. The site loads its own fonts and processing engines and has no advertisements or session replay. The public site uses Google Analytics to measure visits: Google receives the pages you open, browser and device details and your IP address, and sets cookies. The files and text you process are not sent to Google.
Storage and clearing
This build does not persist your input in cookies, local storage, IndexedDB, or a service-worker cache. Browser caching may retain application assets. Clear removes content from the current workspace; it cannot promise forensic erasure of browser or operating-system memory.
Network diagnostics
IP, DNS and speed tools make server requests. IP observation returns the address seen on its configured request path. DNS checks send the entered name and record type to ToolMellow and selected probes, which query Cloudflare or Google Public DNS. The broker does not forward the visitor’s address to a resolver; that provider sees the probe address and query.
Speed measurements begin only after Start and transfer capped synthetic bytes, never your files. The server counts and discards uploads. Application admission keys use temporary salted address hashes in memory; the persistent speed budget stores aggregate reserved bytes and its UTC date, without addresses or queries. Reports remain in tab memory unless downloaded. The application does not log request bodies, DNS answers, query names, address results or speed-session tokens. Hosting infrastructure can still log connection addresses and request metadata.
