Frequently Asked Questions

WizlyTools is a free online platform with 190+ tools for file conversion, image editing, PDF processing, text manipulation, SEO analysis, developer utilities, and calculators. All tools run entirely in your browser — no files are uploaded to any server.

Yes, completely free. There are no premium tiers, no file size limits, no daily usage caps, and no account registration required. Every tool is available to everyone at no cost.

No. WizlyTools requires no sign-up, login, or registration. Just visit any tool page and start using it immediately.

WizlyTools works in all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Brave. We recommend using the latest version of your browser for the best experience.

Yes. All tools are fully responsive and work on mobile devices and tablets. The interface automatically adapts to your screen size.

No. All processing happens locally in your browser using JavaScript. Your files never leave your device. This is not just a claim — you can verify it by checking your browser's network tab while using any tool. There are zero file upload requests.

Yes. Since all conversions happen client-side in your browser, your data never travels over the internet. This makes WizlyTools safe for sensitive business documents, personal data, financial spreadsheets, and confidential files.

We use Google Analytics to understand aggregate usage patterns (which tools are popular, page views, etc.). We do not track individual file conversions, store any file data, or use tracking cookies for advertising purposes. See our Privacy Policy for full details.

Nothing — because we never had it. Your files are processed in your browser's memory and are discarded when you close the tab or navigate away. There is no server-side storage at all.

WizlyTools supports 20+ formats including CSV, JSON, Excel (XLSX), XML, YAML, PDF, DOCX, Markdown, SQL, HTML, PNG, JPEG, GIF, SVG, WebP, HEIC, TIFF, and more. Each format supports conversion to multiple target formats.

There is no hard file size limit. However, since processing happens in your browser, very large files (over 100MB) may be slower depending on your device's memory and processing power. For most files under 50MB, conversion is nearly instant.

Common reasons include: corrupted or invalid input files, unsupported file variations, or insufficient browser memory for very large files. Try refreshing the page and re-uploading. If the issue persists, please report it via our Contact page with details about the file format and size.

Yes. Most converter tools support batch mode, allowing you to upload and convert multiple files simultaneously. Look for the "Batch Mode" toggle on converter tool pages.

For text-based formats (CSV, JSON, XML, YAML, etc.), conversions are lossless — no data is lost. For image conversions, formats like PNG are lossless, while JPEG and WebP use high-quality compression (92% quality) that is visually indistinguishable from the original for most purposes.

WizlyTools supports PNG, JPEG/JPG, GIF, SVG, WebP, HEIC/HEIF (Apple photos), and TIFF. You can convert between these formats and use editing tools like crop, resize, compress, flip, grayscale, pixelate, and more.

Yes. Our HEIC to JPG and HEIC to PNG converters handle Apple's HEIC/HEIF format. Simply upload your iPhone photo and it will be converted instantly in your browser.

Our Image Compressor uses smart algorithms to reduce file size while preserving visual quality. You can adjust the quality slider to balance between file size and image quality. The tool shows a real-time preview and file size comparison.

Yes. Our PDF Merge tool lets you combine multiple PDF files into a single document. You can reorder pages by dragging and dropping before merging.

Yes. Our PDF Compress tool reduces file size by optimizing images, removing metadata, and applying efficient compression. You can choose between different compression levels.

Most PDF operations (merge, split, rotate, reorder pages, add watermarks, page numbers) are done entirely in your browser. Some advanced operations like PDF to Word conversion use our secure backend service, which processes files temporarily and deletes them immediately after conversion.

Yes. Our PDF Protect tool lets you add password encryption to your PDF files. The encryption is applied in your browser, so the unprotected version never leaves your device.

WizlyTools offers JSON Formatter & Validator, Regex Tester, Base64 Encoder/Decoder, Hash Generator (MD5, SHA-256, etc.), UUID Generator, Color Converter, URL Encoder/Decoder, JWT Decoder, Lorem Ipsum Generator, Text Diff, and more.

Yes. Our JSON Formatter & Validator parses your JSON, highlights syntax errors with line numbers, and can auto-format/beautify your JSON with proper indentation.

WizlyTools is built with Next.js 15 and React 18, using modern browser APIs like the File API, Canvas API, Web Workers, and WebAssembly for high-performance client-side processing. The UI uses Tailwind CSS and shadcn/ui components.

Client-side processing means: (1) Your files never leave your device, ensuring complete privacy. (2) No upload/download wait times — processing starts instantly. (3) Works offline after the page loads. (4) No file size limits imposed by server constraints. (5) Zero risk of data breaches from server compromises.

Partially. Once a tool page has loaded, most tools will continue to work even if you lose internet connection, since all processing is client-side. However, you need an internet connection to initially load the page.
