Frequently Asked Questions
Do I need to upload my files to a server?
No. All 26 FindUtils converters process files entirely in your browser using client-side JavaScript, HTML5 Canvas API, and WebAssembly. Your files never leave your device or get uploaded to any external server. This is fundamentally different from most online converter tools that require uploading your files to cloud servers for processing. When you select a file in FindUtils, it is loaded directly into your browser's memory, processed using local code, and the converted output is generated without any network requests. This makes FindUtils safe for converting proprietary documents, confidential spreadsheets, client images, and any other sensitive files that should not be shared with third-party services.
What file size limits exist?
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.
Can I batch convert multiple files?
Yes. Many FindUtils converters support batch processing for converting multiple files at once. The image 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.
What video formats are supported?
FindUtils video tools support the major web-compatible formats including MP4 (H.264), WebM (VP8/VP9), and GIF for output. Input format support depends on your browser's built-in codec availability, which typically includes MP4, WebM, MKV, AVI, and MOV on most modern browsers. Beyond format conversion, the video tools include trimming to extract specific segments, compression to reduce file size, rotation and flipping, frame extraction to capture screenshots, and audio extraction to separate audio tracks into MP3 or WAV files. All video processing runs in your browser using WebAssembly-based FFmpeg, providing near-native performance without any server uploads.
