Fastsoft
About Fastsoft
Fastsoft is a free toolbox for everyday image, text and developer tasks. Its purpose is to make small jobs easy to start, easy to inspect and clear about their limits.
What you can do here
The site includes image compression and conversion, color extraction, QR codes, text cleanup, and developer utilities for JSON, regular expressions, HTTP and WebSocket. Browse or search from the home page. Each tool has a practical guide with an example and limitations.
Browse all toolsWhere data goes
Image, text, QR-code and random-value tools mainly process data in your browser, without a Fastsoft application server. The HTTP and WebSocket tools connect directly to the destination you enter, which may receive and log requests. Google Analytics and AdSense may also load; see the privacy page.
Read privacy detailsReview the result
Browser image conversion can drop metadata. Base64 is not encryption. CORS can prevent a web page from reading an API response. Generated code and secrets need to be reviewed and stored appropriately for your own system. Tool pages explain these limits in context.
