ConvertYard is an online platform for file conversion that utilizes WebAssembly technology to ensure all processing occurs locally, keeping your files secure within your browser. For images, it allows conversions among HEIC, JPG, PNG, WebP, and AVIF formats while also offering bulk capabilities to compress, resize, and eliminate backgrounds. In terms of PDF management, users can merge multiple PDFs, reduce file sizes, extract or delete pages, crop documents, add page numbers, and even export pages as images. For multimedia, it facilitates conversions between various video and audio formats, along with the ability to extract audio tracks from video files. Developers can take advantage of utilities that format JSON, encode and decode Base64, and convert JSON into CSV files. Additionally, AI tools are available to automatically generate alt text for images, enhancing accessibility for users. All features enable batch processing of as many as 1,000 files in a single operation, and the results can be conveniently downloaded as a single ZIP file. There's no need to create an account, and users won’t encounter watermarks or restrictions based on file sizes. After the first page load, the service works offline thanks to WebAssembly caching, providing a streamlined experience with a clean interface devoid of advertisements throughout the conversion process. This ensures that users can focus on their tasks without distractions while taking advantage of the extensive functionalities offered by ConvertYard.

You can easily resize, convert, or compress multiple images in one go by browsing for and selecting the files or folders you wish to work with; simply drag and drop the images or select a zip file containing them. Alternatively, you can paste an image directly from your clipboard, though keep in mind that the operation is limited by your system's available memory. Each image will be processed separately, but be prepared for the memory requirement to be 3 to 4 times larger than the combined size of the images when they are downloaded as a zip file. The image processing is executed via JavaScript, and note that the browser may limit CPU resources for tabs that are not currently in focus, so it's best to keep the browser tab active to speed up the process. For optimal results when compressing PNG or BMP files, adjust the color depth to 8-bit, while for JPEG, WEBP, or HEIC formats, lowering the quality setting will help reduce file size. In the batch configuration area, you can either choose a predefined task or customize each option as needed. After processing, you can easily review the images by expanding the list, and by clicking on a file name, you can view the respective image in detail. This user-friendly interface allows for efficient image management and editing, making it a versatile tool for your image processing needs.
