Frequently Asked Questions
Comprehensive answers regarding our suite, security standards, and features.
What makes ProLink different from other online tool websites?
Unlike conventional web converter sites that flood users with disruptive popups, force file uploads to overseas servers, and impose arbitrary daily limits, ProLink operates entirely client-side. Your files remain on your computer, conversions occur instantly, and there are no fees or signups.
Do I need to create an account to use these tools?
No. Every single utility across the ProLink tools suite is 100% accessible with zero registration. You never have to share your email address or create a password.
Are my phone numbers, messages, or files logged?
No. ProLink has a strict privacy policy: inputs are computed locally in your web browser. We never log phone numbers, harvest marketing contacts, or store uploaded graphic files.
How many images can I convert or compress at one time?
You can process as many images as your computer's memory can handle—whether that is 5, 20, or 50 images in a batch. There are no artificial software quotas.
Can I print the QR codes on commercial products?
Yes. The QR codes produced by ProLink are rendered at high resolution adhering to ISO/IEC 18004 standards, making them suitable for high-dpi physical printing on signage, product packaging, and business cards.
Is the BMI Calculator based on international medical standards?
Yes. Our Body Mass Index calculator utilizes official World Health Organization (WHO) classifications, and our BMR calculation is powered by the clinically validated Mifflin-St Jeor formula.
Can I convert transparent PNGs to JPG without black backgrounds?
Yes. Our Image Converter includes a custom Background Fill color picker (defaulting to pure white #FFFFFF), preventing the common issue of transparent PNG cutouts turning black when converted to JPG.
Does ProLink work offline?
Because the core conversion engines and mathematical algorithms run inside client-side JavaScript, once the web page is loaded into your browser, tools like the BMI Calculator, Image Converter, Image Compressor, and Text Styler continue functioning even if your internet connection drops.
Are all ProLink tools 100% free with no hidden charges or subscription limits?
Yes. Every tool in the ProLink suite is completely free with no usage limits, no credit card requirements, no account registration gates, and no watermarks.
How does ProLink protect user data and file privacy?
ProLink uses zero-upload client-side processing architecture. Whether you are generating QR codes, compressing high-res photos, compiling PDFs, or calculating BMI, the computations execute entirely inside your local web browser session. No files or private inputs are ever sent to remote servers.
