re;file labs is built to prioritize your privacy. All file conversions happen securely in your browser through WebAssembly (WASM) technology, which runs within a sandboxed environment. This means your files never leave your device. No data is sent to external servers; everything is processed locally to maintain complete data confidentiality.
Unlike many online converters, re;file labs processes images directly in your browser using WebAssembly and Rust for enhanced security and performance. This setup ensures your files remain secure and private, without needing any uploads. Additionally, re;file labs uses a worker thread for multi-threaded processing, so it runs fast without slowing down your computer.
Yes! re;file labs supports a wide range of image formats, allowing you to convert images between different file types seamlessly. Common conversions like PNG to JPEG or BMP to GIF, as well as more specialized formats, are supported, making it versatile for various image conversion needs.
Rust is known for its strong focus on security and performance, which makes it ideal for an image processing tool like re;file labs. WebAssembly (WASM) allows this Rust code to run directly in the browser at near-native speeds, with full sandboxing. This combination provides a secure and efficient experience, ensuring fast conversions without compromising on privacy.
Not at all. re;file labs runs in a separate worker thread in your browser, meaning it operates independently without impacting your computer's performance. The multithreading support ensures conversions are fast and efficient, even for larger files, so you can continue using your device as usual.
Yes, re;file labs supports SVG conversions, allowing you to convert vector graphics to raster formats like PNG, JPEG, and more. This is especially useful if you need a static image version of an SVG for use on websites or in applications that don't support SVG files.
Thanks to WebAssembly and multithreaded processing, re;file labs performs image conversions quickly and efficiently. This speed is especially noticeable with larger files or batch conversions, making it ideal for users who need high-performance image processing on the fly.
Once loaded in your browser, re;file labs can continue working without an internet connection. This offline capability is possible because all file processing happens within your browser using WebAssembly, so you're not dependent on a server connection. Furthermore, re;file labs is a progressive web app (PWA), so you can install it on your device for easy access anytime.
Yes, re;file labs includes metadata editing tools for images, allowing you to view and modify information like image title, author, and copyright. This feature is valuable for those who want to organize or update their image metadata without needing separate software.
Absolutely. re;file labs is designed to handle multiple files efficiently through its multithreaded processing capabilities. Whether you need to convert several images at once or process a single large file, re;file labs is optimized for quick, reliable performance.
In addition to image files, re;file labs has a suite of tools for managing PDFs, document metadata, and more. As we expand, you can expect additional functionalities to make re;file labs a comprehensive tool for various file-related needs.
