Is NexaTools free to use?

Yes, completely. Every tool on NexaTools is free with no sign-up, no subscriptions, no credit cards, and no usage quotas.

Do my files or text inputs ever leave my browser?

No. All processing for PDF manipulation, media conversions, image compression, formatting, and mathematical calculations runs locally on your device via client-side WebAssembly and JavaScript. Your files are never uploaded to any remote server.

What information should I include in a bug report?

To help us resolve the issue swiftly, please mention the tool URL, your browser name and version, device OS (Windows, Mac, Linux, Android, iOS), a description of what occurred, and any console error messages or screenshots if possible.

Can I request a new tool or feature?

Yes! We actively build tools based on real developer and creator workflows. Email us at support@nexatools.in with [Feature Request] in the subject.

How fast does the NexaTools team reply?

We typically respond within 24 to 48 hours Monday through Saturday. Priority security inquiries are triaged within 12 hours.

Are there file size limits on browser-side converters?

Because files are processed directly in your browser memory, limits depend on your device RAM. Files up to several gigabytes can be handled smoothly on modern desktops.

Before Reaching Out: Quick Diagnostics

90% of common tool errors stem from aggressive browser extensions or stale service worker caches. Try these 3 steps first:

1. Hard Refresh Cache Press Ctrl + Shift + R (Windows) or Cmd + Shift + R (Mac) to ensure your browser loads the newest WebAssembly modules.

2. Try Incognito / Private Strict adblockers or privacy extensions can occasionally block client-side WebAssembly memory buffers from instantiating.

3. Check Available RAM Media conversion and large PDF rendering happen 100% in your device RAM. For files above 1GB, close unneeded browser tabs.

Frequently Asked Questions

Is NexaTools completely free to use?

Yes, 100% free. Every utility, converter, calculator, and developer tool on NexaTools is available without accounts, paywalls, monthly subscription charges, or hidden watermarks.

Do my files or text inputs ever get uploaded to your servers?

No. NexaTools is built on a local-first philosophy. All PDF modifications, media conversions (via FFmpeg WebAssembly), image compression, and text manipulation run solely in your browser's local sandbox memory. When you close the tab, all working data disappears instantly.

What information should I include when submitting a bug report?

The fastest way to help us fix a bug is to mention: (1) The exact tool URL, (2) Your browser and version (e.g. Chrome 128, Firefox 130), (3) Your operating system, (4) File format/size if applicable, and (5) Any error message shown in the browser developer console.

Can I suggest a new tool or calculator to be added?

Absolutely! Much of our tool catalog was built directly from user feedback. Email us at support@nexatools.in with a description of the tool, inputs/outputs needed, and sample use cases.

Can I install NexaTools as an offline app?

Yes. NexaTools is a Progressive Web App (PWA). Click the "Install App" or "App Portal" button in the navigation header on Chrome, Edge, or Android to install it directly to your home screen or desktop taskbar for instant offline access.

Are there file size limits on browser tools?

Because there are zero server uploads, limits are determined only by your computer's RAM. We regularly test audio, image, and PDF workflows with files up to 500MB–2GB on standard laptops without issue.

How does NexaTools handle user privacy?

We do not collect personal profiles, do not require registration, and do not track user files. We only use anonymous privacy-compliant aggregate traffic metrics to observe popular tools and uptime. Read our complete Privacy Policy for full disclosures.
