Question 1

Are my files or text uploaded to any remote servers?

Accepted Answer

No. Absolutely nothing is uploaded. All processing takes place 100% locally within your web browser using modern Web APIs (Web Audio, Canvas, WebAssembly, PDF.js, and Web Cryptography). Your files and text never leave your computer or phone.

Question 2

Is BuzzyTools safe for confidential, legal, or financial files?

Accepted Answer

Yes, it is safer than traditional online converter sites. Because your files never travel over the network to any server, there is zero risk of data interception, server breaches, or third-party storage. Everything is processed in your browser's private memory sandbox.

Question 3

Do you store generated QR codes, passwords, or personal contacts?

Accepted Answer

Never. Information you enter for Wi-Fi credentials, vCard contact cards, WhatsApp messages, or passwords is generated directly on your screen and discarded immediately as soon as you close or refresh the tab.

Question 4

Why are the tools on BuzzyTools faster than other converter websites?

Accepted Answer

Conventional converter websites require you to upload your file to their server, wait in a processing queue, and then download the output file. BuzzyTools eliminates network upload and download wait times completely—your own device's processor handles the task instantaneously.

Question 5

Can I use BuzzyTools offline without an active internet connection?

Accepted Answer

Yes! Once you have opened any tool page in your browser, the script files remain cached. You can disconnect your internet, turn on airplane mode, and continue converting audio, editing PDFs, formatting text, or generating QR codes completely offline.

Question 6

What are the file size limits and why do they exist?

Accepted Answer

Because processing happens directly inside your browser's RAM, limits ensure your browser stays responsive and does not crash. For example, video tools support up to 200 MB, PDF batch operations up to 100 MB, and images up to 25 MB. These cover almost all everyday tasks with maximum speed.

Question 7

How do video trimming, speed change, and muting work in the browser?

Accepted Answer

We utilize native browser media elements and Canvas/MediaRecorder APIs. The browser decodes the frames locally, applies the selected speed (from 0.25× to 4×) or clips the time range, and packages the result into a browser-supported container (WebM or MP4) without needing third-party software.

Question 8

Can I extract pure audio from a video file?

Accepted Answer

Yes! Our Video Trimmer tool features an 'Extract Audio (WAV)' option. It separates the audio track from the video and exports it as an uncompressed, studio-quality WAV audio file directly to your downloads.

Question 9

What audio adjustments can I make with the Audio tools?

Accepted Answer

You can convert any browser-supported audio to WAV, trim segments with millisecond precision, boost or lower volume up to 200%, normalize audio peaks to prevent clipping, and convert between Mono and Stereo channel layouts.

Question 10

What can I do with PDF tools without uploading my documents?

Accepted Answer

You can merge multiple PDFs, split documents by page ranges, extract specific pages, rotate orientations (90°, 180°, 270°), delete unwanted pages, reorder pages, add custom page numbers or watermarks, convert images to PDF, and export PDF pages to crisp PNG, JPEG, or WebP images.

Question 11

What is the File Inspector and what are 'Magic Bytes'?

Accepted Answer

File extensions can easily be renamed or faked (e.g., an executable named .png). The File Inspector reads the true binary signature header bytes (known as Magic Bytes) of any file to verify its authentic file type, exact byte size, and MIME type without executing or opening it.

Question 12

How does the Hash & Checksum Verifier protect against corrupted downloads?

Accepted Answer

When software developers publish files, they provide a hash (like SHA-256 or SHA-512). Our Checksum tool computes SHA-256, SHA-1, and SHA-512 simultaneously in your browser. You can paste the official checksum into our live verifier to confirm whether the file is authentic and 100% uncorrupted.

Question 13

What features are supported in the QR Code Generator?

Accepted Answer

You can create customized QR codes for URLs, plain text, Wi-Fi networks, vCard business cards, pre-filled WhatsApp chats, phone numbers, and emails. You can customize colors, adjust error correction levels, upload a custom center logo, and download high-resolution PNG or vector SVG files.

Question 14

Why does the QR Scanner request camera permissions?

Accepted Answer

Camera access is requested only when you choose the live camera scanning mode. The camera stream is analyzed frame-by-frame purely inside your device's memory to detect QR codes. No video is ever recorded, stored, or streamed over the internet. You can also upload an image file instead.

Question 15

How does the Arabic Text Normalizer improve text formatting?

Accepted Answer

It removes Tashkeel diacritics and Tanween, unifies Alef variants (أ, إ, آ to ا), standardizes Taa Marbouta (ة/ه) and Yaa (ى/ي), removes Kashida elongation, converts between Eastern Arabic and Western digits, and cleans irregular spacing for optimal readability and search indexation.

Question 16

Is BuzzyTools really 100% free? Are there any subscriptions or watermarks?

Accepted Answer

Yes, every tool on BuzzyTools is completely free to use. There are no subscriptions, paywalls, credits, or hidden fees. We do not insert watermarks or branding onto your exported images, PDFs, or videos.

Question 17

Do I need to sign up or create an account to use the tools?

Accepted Answer

No. You never have to register, log in, or provide an email address. Simply visit the tool page and start using it immediately.

Question 18

Which browsers and operating systems are supported?

Accepted Answer

BuzzyTools works seamlessly on any modern web browser that supports HTML5 standards, including Google Chrome, Apple Safari, Mozilla Firefox, Microsoft Edge, Brave, and Opera. It works across Windows, macOS, Linux, iOS (iPhone and iPad), and Android mobile devices.
