Questions about our free tools

Are the tools really free?+

Yes. Every tool is free with no sign-up, no watermark and no usage limits.

Are my files uploaded to your servers?+

Most tools run entirely in your browser, so your images, PDFs, text and passwords never leave your device. The few tools that use a public service, such as DNS or WHOIS lookups, say so on their page.

Do the QR codes I make expire?+

No. Our QR codes are static: the data is stored inside the code itself, so there is nothing to expire or switch off.

Can I use the results commercially?+

Yes. What you create, such as QR codes, barcodes, compressed images or invoices, is yours to use for personal or business purposes.

Do they work on my phone?+

Yes. All tools are responsive and work in modern mobile browsers.
