Question 1

How does xdevutilities protect user data and files?

Accepted Answer

We operate on a strict Zero-Persistent-Storage architecture. Client-side tools (like Privacy Blur, Safe Zone Checker, and Fair Price Estimator) process data 100% locally in your browser canvas. For cloud-powered utilities (like ATS Resume Scanner and PDF Metadata Cleaner), payloads are processed statelessly in volatile RAM and immediately wiped upon completion. We do not maintain user databases or track usage history.

Question 2

Can I safely use the Private Message Encryptor for sensitive credentials?

Accepted Answer

Yes. The Message Encryptor utilizes military-grade AES-256 bit symmetric cryptography executed via stateless endpoints. Your private passphrase and plaintext are never committed to any database, file system, or analytics pipeline. Only recipients with your unique secret passphrase can decrypt the resulting ciphertext.

Question 3

Do I need to create an account to use the utilities?

Accepted Answer

No, account registration is completely optional. All 10 utilities are instantly accessible without mandatory logins or paywalls. Registering an account is solely provided for users who wish to bookmark preferred tools or retain personalized workspace settings.

Question 4

Why are all tools free to use?

Accepted Answer

Our mission is to provide high-performance, distraction-free utilities that replace bloated, ad-ridden web software. To cover high-speed infrastructure costs while keeping tools free for everyone, the platform is supported by ethical, non-intrusive sponsorships and advertisements without selling user data.

Question 5

Which SQL dialects are supported by SQL to Mermaid?

Accepted Answer

The parser supports standard ANSI SQL CREATE TABLE statements from PostgreSQL, MySQL, SQLite, and Microsoft SQL Server. It automatically interprets table columns, primary keys, and data types into declarative Mermaid markdown and lossless, infinitely zoomable SVG vector diagrams.

Question 6

How does the Code to Image Converter export high-resolution assets?

Accepted Answer

Our engine uses Prism.js for syntax highlighting and renders the snapshot at 3x pixel density (Retina-ready) using the browser Canvas API. This prevents pixelation and ensures your code snippets remain crisp on high-DPI social feeds like LinkedIn and X (Twitter).

Question 7

How does Privacy Blur achieve seamless redaction?

Accepted Answer

In addition to standard Gaussian Blur and solid Blackout masks, Privacy Blur features an 'Auto Match' algorithm. It samples surrounding perimeter pixels to fill the redacted box with the exact background color, seamlessly blending text or UI elements into the canvas.

Question 8

What makes the ATS Resume Scanner different from keyword counters?

Accepted Answer

Our scanner executes semantic natural language parsing rather than simple word counting. It checks structural resume sections (experience, contact details, education) and measures keyword density against the provided job description to evaluate true applicant tracking compatibility.

Question 9

What dimensions are generated by the Passport Photo Maker?

Accepted Answer

It produces a standard 300x300 pixel square JPEG crop formatted for digital ID portals and general visa applications. For optimal compliance, we always recommend uploading a portrait with a neutral expression taken against a plain, evenly lit white backdrop.

Question 10

How does the Social Media Safe Zone Checker prevent profile overlap?

Accepted Answer

Different viewports dynamically scale banner graphics and shift circular user avatars. Our tool maps real-time boundary overlays for LinkedIn, YouTube, X, and Instagram, highlighting 'Danger Zones' where mobile UI elements crop vital text or logos.

Question 11

How does the Fair Price Estimator handle non-standard quantities?

Accepted Answer

The calculator performs multi-unit dimensional analysis across weight (kg/g), volume (l/ml), and count (pcs). It determines the exact base-unit market cost from a standard reference item, revealing hidden retailer margins, rounding markups, and shrinkflation.
