Cropping removes edges and changes the visible frame (like cutting a photo). Resizing scales the entire frame to new dimensions without removing content—use /tools/video-resizer when you need to change resolution without cutting. Are my videos uploaded to a server? No. Crop and encode run locally after the FFmpeg engine loads once (~25 MB on first use). Your file stays on your device unless you share the download elsewhere. What is the maximum file size? Uploads are limited to 200 MB per file, similar to common online video croppers. Long 4K clips may be slow on low-memory devices—try a shorter segment first.
