Support & Help

No. Every tool on DevZone runs entirely in your browser using client-side JavaScript. Your text, images, files, and data are never transmitted to our servers. You can open your browser's network inspector and verify: no requests are made to our servers when you use a tool.

We use Google Analytics (GA4) to count page views and understand which tools are most used — this helps us prioritize improvements. GA4 may set analytics cookies. We do not use advertising cookies, retargeting pixels, or session recording. You can decline analytics cookies via the consent banner shown on your first visit.

Some tools save your last-used settings (like brush size or compression quality) to localStorage so they persist between sessions. This data never leaves your device. You can clear it at any time via your browser's developer tools or site settings.

Most tools are fully client-side and continue to work without an internet connection once the page has loaded. Tools that rely on external libraries (like the PDF tools or audio converter) may need to download assets on first use, then work offline thereafter.

Heavy processing tasks — image compression, PDF parsing, audio conversion — run directly in your browser, which means performance depends on your device's CPU and RAM. On older or lower-powered devices, processing large files may be slow. Try reducing file size or using a modern desktop browser for best results.

First, verify the input is valid for that tool (e.g., well-formed JSON for the JSON formatter). If the input looks correct and the output is still wrong, please report it via email with a description of the input and expected output. We fix confirmed bugs quickly.

DevZone Tools works in all modern browsers: Chrome 90+, Firefox 90+, Safari 15+, and Edge 90+. Internet Explorer is not supported. Some advanced features (like the screen recorder or audio processing) require browser APIs that may not be available in older browser versions.

No. DevZone Tools has no accounts, no sign-up, and no login. All tools are accessible immediately without any registration. This is a deliberate design choice — we don't collect accounts because we have no use for them.

No artificial limits are imposed. The practical limit is your browser's available memory and your device's processing speed. Very large files (100 MB+) may cause memory issues on some devices.

Yes. The full suite of tools is and will remain free. There is no freemium tier, no "Pro" version, and no paywalled features. The site is supported by a small banner ad that helps cover hosting costs.

Yes, and we genuinely build tools based on requests. Email devzonetools@gmail.com with what you need. Most of the tools that exist today were built because someone asked for them. We can't promise to build everything, but good requests typically land within a few weeks.

Email devzonetools@gmail.com with: which tool you were using, what you did, what you expected to happen, and what actually happened. A screenshot or copy of the problematic input helps a lot.
