Your files are processed on your device

Most tools run entirely in your browser using modern web technology. When a tool converts, merges or compresses a file, the work happens on your device, so the file is not sent to our servers.

No unnecessary uploads

File and text processing happens locally. We have no upload endpoint for your documents.

No account needed

Open a tool and use it. There are no accounts.

Fast, because it is local

No upload and download round trip. Heavy work runs in background threads so the page stays responsive.

Honest about limits

Browser memory and your device set the limits. Each tool page explains what to expect.

There are no accounts. Optional analytics runs only if you allow it and never includes your file contents.

Frequently asked questions

Are my files uploaded to your servers?

For the tools in this directory, no. Processing happens in your browser and the files are not uploaded to our servers. If a feature ever needs the network, it says so explicitly.

Do I need an account?

No. There are no accounts. Every tool works without signing up.

Is it really free?

Yes. Every tool is free to use.

Which browsers are supported?

Current versions of Chrome, Edge, Firefox and Safari. A few formats, such as AVIF encoding, depend on the browser and are marked on the tool page.

How large a file can I process?

That depends on your device memory. Each tool page explains its limits.
