Frequently Asked Questions

Everything you need to know about ZeroTools and how our free online tools work.

What is ZeroTools and what tools do you offer?

Our toolkit includes a QR Code Generator, Hashtag Generator, Image Compressor, Background Remover (AI-powered), PDF Compressor, File Converter, Password Generator, Color Palette Generator, Lorem Ipsum Generator, JSON Formatter, Word Counter, Case Converter, Base64 Encoder/Decoder, and more.

Are all ZeroTools really free to use?

Yes, every single tool on ZeroTools is completely free — forever. There are no hidden premium tiers, no account creation required, and no credit card needed. We sustain the platform through non-intrusive display advertising (Google AdSense), which allows us to keep all features accessible to everyone without limitations.

Is it safe to use? Are my files uploaded to a server?

Absolutely safe. ZeroTools is designed with a privacy-first architecture. All processing happens locally in your browser using modern Web APIs such as Canvas, WebAssembly, and FileReader. Your images, PDFs, passwords, and text never leave your device. We have zero access to your files — they are never uploaded, stored, or transmitted to any server.

How does client-side processing work?

Instead of sending your files to a remote server for processing, ZeroTools leverages the computing power of your own device. Technologies like the HTML5 Canvas API (for image manipulation), WebAssembly (for AI-powered background removal), and the JavaScript File API (for reading and converting files) allow all operations to run entirely within your web browser. This means instant results, total privacy, and no dependency on internet speed for processing.

Can I use ZeroTools on my phone or tablet?

Yes! All tools on ZeroTools are built with a fully responsive design and work seamlessly on smartphones (iPhone, Android), tablets (iPad), and desktop computers. Simply open myzerotools.online in your mobile browser (Chrome, Safari, Firefox) and start using any tool. Note: some computation-heavy tools like the AI Background Remover may run slower on older mobile devices.

What image formats does ZeroTools support?

Our image tools support a wide range of formats. The Image Compressor accepts JPG, PNG, GIF, BMP, and WebP files, with output options for JPEG, PNG, and WebP. The File Converter lets you switch between JPG, PNG, WebP, GIF, and BMP formats. The Image Cropper works with JPG and PNG files and exports to JPG, PNG, or WebP. The Background Remover accepts JPG and PNG inputs and always outputs a transparent PNG.

Do you display ads on the website?

Yes, ZeroTools uses Google AdSense to display non-intrusive banner advertisements. This is how we keep every tool free for all users. We carefully position ad placements so they do not interfere with your workflow. Ads never cover your tools, never auto-play audio, and never block your results.

How can I report a bug or suggest a new tool?

We love hearing from our users! If you found a bug, have a feature request, or want to suggest a new tool, please send us an email at HelloZeroTools@outlook.com. We read every message and typically respond within 24 hours. Your feedback directly shapes the future of ZeroTools.
