Converters

Not on the converter pages. A FindUtils converter page reads the file you select into browser memory and converts it with client-side JavaScript, the HTML5 Canvas API, or WebAssembly, so the file is not uploaded. Most online converters work the other way and upload your files to a cloud server first. That makes the pages suitable for proprietary documents, confidential spreadsheets, client images, and other files that should not be shared with a third party. The REST and MCP API is a separate path: many of these tools can also be called from code, and a call sends the input you include to FindUtils over HTTPS, where it is processed and the result returned. FindUtils does not store that input, and logs the request without its content. Each tool page shows a Run it from code card when the tool has an API.

File size limits depend on your browser's available memory rather than any arbitrary server limits. Most modern browsers on desktop computers can handle files up to 100MB or larger without issues. Mobile browsers may have lower limits due to device memory constraints, typically around 30-50MB. For image conversions, the practical limit is determined by the image dimensions after decoding rather than the compressed file size. If you encounter memory issues with very large files, try closing other browser tabs to free up memory. There are no daily usage caps, no file count limits, and no throttling. You can convert as many files as needed, as often as you want, with no restrictions.

Yes. Many FindUtils converters support batch processing for converting multiple files at once. The image converter, HEIC to JPG converter, image resizer, and image compressor all accept multiple file selections through drag-and-drop or the file picker. You can select dozens of files at once, configure your conversion settings, and process them all in a single operation. The batch results are available for individual download or as a combined ZIP archive. Batch processing runs sequentially in your browser to manage memory efficiently. Progress indicators show the status of each file in the batch. This is particularly useful for tasks like resizing a folder of product photos, converting a set of PNGs to WebP format, or compressing multiple images for web optimization.

Yes. The HEIC to JPG converter decodes the HEIC and HEIF files an iPhone or iPad produces and writes standard JPGs that Windows, LinkedIn, and upload forms accept. Drop one photo or a batch; a batch downloads as a zip. Decoding runs in your browser through a WebAssembly build of libheif, so the photos are not uploaded anywhere. Location data in the EXIF is stripped by default. Some HDR and Live Photo sequences cannot be decoded; those files are named in an error and the rest of the batch still converts. For video format conversion, see the media tools rather than this hub.
