Your files stay with you.
File tools run in your browser. The Instagram downloader uses a server and explains this before sending the link. No accounts or document uploads.
This is how we take care of your privacyBefore starting
Are they really free?
Yes. The tools available do not require an account or payment. Size limits protect device memory.
Can I use them from my mobile?
Yes, with a modern browser. On devices with less memory, use smaller files. Format support may vary.
Do I need an internet connection?
Internet is needed to load the site and its modules. Local tools can work with an offline copy; the Instagram downloader always needs internet. Activate the copy using the install button. Only public resources are saved, never your files, submitted links or results.
A small collection of tools. A great help for everyday life.
