Frequently Asked Questions

Loopaloo is a free collection of 236+ online tools designed for developers, designers, content creators, and everyday users. Our tools cover image processing, PDF manipulation, video and audio editing, data analysis, text utilities, converters, math tools, web development utilities, and even browser-based games. Every tool runs entirely in your web browser, meaning your files are never uploaded to any server.

Yes, Loopaloo is completely free to use. There are no premium tiers, no hidden limits, no watermarks, and no subscription fees. Every tool offers full functionality without requiring you to create an account or pay anything. We sustain the platform through non-intrusive advertising and voluntary donations via Ko-fi.

No. You can use every tool on Loopaloo immediately without signing up, logging in, or providing any personal information. We do not have a user account system because we believe tools should be accessible without barriers.

Loopaloo currently offers 236+ tools across 10 categories: Image Processing, Audio Processing, Video Processing, Document & Text, PDF Tools, CSV & Data Analysis, Converters & Encoders, Web Tools, Math & Science, and Games. We regularly add new tools based on user feedback and emerging needs.

Loopaloo is built and maintained by a team of software engineers with deep expertise in web platform technologies, client-side processing, and user experience design. We specialize in WebAssembly, Web Worker architectures, and browser API optimization to deliver tools that rival native desktop applications.

No. This is the core principle behind Loopaloo. Every tool processes your files entirely within your web browser using technologies like WebAssembly, the Canvas API, Web Workers, and the Web Audio API. Your files never leave your device. We physically cannot see, access, or store your content because it never reaches our servers.

Modern web browsers include powerful technologies that enable complex file processing directly on your device. Loopaloo leverages WebAssembly (WASM) for near-native performance in video, audio, and image processing; Web Workers for background threading that keeps the interface responsive; the Canvas API and WebGL for real-time image manipulation with hardware acceleration; and the Web Audio API for professional audio processing. All of this runs locally using your device's own computing power.

We use Vercel Analytics for basic, anonymous site analytics (page views, general traffic patterns) to help us understand which tools are popular and improve the platform. We do not track which files you process, the content of your files, or any personally identifiable information about your tool usage. Your preferences (like favorites and recent tools) are stored locally in your browser's Local Storage and never sent to our servers.

Yes. Because all processing happens in your browser, sensitive documents like financial records, medical documents, legal contracts, and confidential business files are processed in complete privacy. The files exist only in your browser's memory during processing and are never transmitted over the internet. This makes Loopaloo suitable for handling documents that contain private or proprietary information.

Yes. Since no files are uploaded to external servers, Loopaloo is compliant with strict corporate data policies. IT departments can verify this by monitoring network traffic while using our tools - they will see that no file data is transmitted. This makes Loopaloo a practical choice for organizations that handle sensitive data and restrict the use of cloud-based file processing services.

Loopaloo supports a wide range of file formats across all categories. For images: PNG, JPEG, WebP, SVG, AVIF, GIF, BMP, TIFF, and ICO. For audio: MP3, WAV, OGG, FLAC, AAC, and WebM audio. For video: MP4, WebM, AVI, MOV, and MKV. For documents: PDF, JSON, XML, YAML, TOML, Markdown, CSV, TSV, and plain text. Each tool's page lists the specific formats it supports.

Because processing happens in your browser, file size limits depend on your device's available memory (RAM) rather than server upload limits. Most modern devices can comfortably handle files up to 100-500 MB. For very large files (1 GB+), performance depends on your device's specs. Desktop computers with 8 GB+ RAM typically handle larger files better than mobile devices. If a file is too large for your device, the tool will notify you.

Processing speed depends on your device's hardware since all computation happens locally. Complex operations like video transcoding, large image batch processing, or PDF manipulation with many pages can take longer on less powerful devices. For the best performance, close unnecessary browser tabs and applications to free up memory and CPU resources. Desktop browsers generally perform better than mobile browsers for intensive tasks.

Many tools support batch processing. For example, the image converter, image compressor, and several other tools allow you to drag and drop or select multiple files simultaneously. Batch processing runs sequentially to avoid overwhelming your device's memory, but it's still faster than processing files one at a time manually.

Loopaloo is a Progressive Web App (PWA) that can be installed on your device. Once the tools have been loaded initially, many of them work without an internet connection. You can install Loopaloo on your desktop or mobile device from the browser's install prompt for the best offline experience.

Loopaloo works best on modern, up-to-date browsers. We fully support Google Chrome (and Chromium-based browsers like Edge, Brave, and Opera), Mozilla Firefox, Safari (macOS and iOS), and Microsoft Edge. Some advanced features like WebAssembly-based video processing require a recent browser version. We recommend keeping your browser updated for the best experience.

Yes, Loopaloo is fully responsive and works on mobile devices. However, some tools work better on desktop with larger screens, especially those involving detailed visual editing (like the drawing canvas or image cropper) or intensive computation (like video processing). For the best mobile experience, we recommend using Chrome on Android or Safari on iOS.

Yes. Loopaloo is a Progressive Web App (PWA) that can be installed directly from your browser. In Chrome, click the install icon in the address bar or go to the browser menu and select "Install Loopaloo." On mobile, use the "Add to Home Screen" option. Once installed, Loopaloo behaves like a native app with its own window, icon, and offline support.

Our PDF tools use the pdf-lib JavaScript library, which runs entirely in the browser. When you select PDF files, they are read into your browser's memory using the File API. The library then manipulates the PDF structure (merging pages, extracting pages, adding watermarks, etc.) directly in memory. The resulting PDF is generated client-side and offered as a download. At no point does the file leave your device.

Yes. Our video tools use FFmpeg.wasm, a WebAssembly port of the powerful FFmpeg multimedia framework. This allows us to perform video conversion, trimming, compression, and audio extraction entirely in your browser. While processing may be slower than a native FFmpeg installation, it offers the same format support and quality without requiring any software installation.

Our image text extractor uses Tesseract.js, a WebAssembly port of the Tesseract OCR engine developed by Google. It supports 100+ languages and works best with clear, well-lit images with good contrast. Printed text typically achieves 90-99% accuracy depending on image quality. Handwritten text recognition is supported but with lower accuracy. For best results, ensure images are at least 300 DPI with sharp, well-contrasted text.

Our games serve multiple purposes. Typing tests help measure and improve typing speed. Memory games and puzzles provide cognitive training. Classic games like Tetris, Minesweeper, and Snake offer quick mental breaks that research shows can improve productivity. All games run in the browser with no ads interrupting gameplay and no data collection.

Yes. We are committed to keeping all existing tools free and fully functional forever. We may introduce optional premium features in the future (like custom branding for exported files), but the core tools will always remain free without limits. We believe essential digital tools should be accessible to everyone.

Loopaloo is built with Next.js (React) and TypeScript for the frontend, with Tailwind CSS for styling. File processing leverages WebAssembly (FFmpeg.wasm for video/audio, pdf-lib for PDFs, Tesseract.js for OCR), Web Workers for background processing, the Canvas API for image manipulation, and the Web Audio API for audio processing. The site is deployed on Vercel with global CDN distribution for fast loading.

Loopaloo uses minimal cookies only for essential functionality like analytics. We do not use tracking cookies or third-party cookies for advertising purposes. Your tool preferences, favorites, and recent tools are stored in your browser's Local Storage, not in cookies. You can review our full cookie and data practices in our Privacy Policy.

Yes. Every tool has its own permanent URL (e.g., loopaloo.com/tools/image-compressor) that you can share or link to from your website, documentation, or social media. The tools are designed to work when accessed directly via URL. We do not currently offer embeddable iframe widgets, but direct links work perfectly.
