# Video Optimizer Optimize video files for web streaming, storage, or playback with intelligent compression and quality preservation > Canonical page: https://elysiatools.com/en/tools/video-optimize - **Category:** Media - **Keywords:** video, optimize, compress, web, streaming, efficient ## Overview The Video Optimizer is a powerful utility designed to compress and optimize video files for web streaming, storage, or playback. By leveraging intelligent compression algorithms, it reduces file sizes while preserving visual quality, allowing you to customize optimization modes, target size reductions, and output formats. ## Inputs - **Video File** (file): Select the video file to optimize - **Optimization Mode** (select): Optimization strategy to apply - **Target Size Reduction (%)** (range): Target file size reduction percentage (10-90%) - **Web Streaming Optimized** (checkbox): Optimize for web streaming (fast start, zero latency) - **Remove Metadata** (checkbox): Remove metadata to reduce file size - **Custom CRF (Optional)** (number): Override automatic CRF calculation (leave empty for auto) - **Output Format** (select) ## When to use - When you need to compress large video files to save local storage space or cloud hosting costs. - When preparing videos for web streaming to ensure fast start times and zero-latency playback. - When converting and optimizing raw video files into web-friendly formats like MP4 or WebM. ## How it works - Upload your video file (up to 500MB) in any standard video format. - Select your preferred optimization mode, target size reduction percentage, and output format. - Enable web streaming optimization or adjust the custom CRF value for precise quality control. - Process the video to download the optimized, compressed file ready for streaming or storage. ## Use cases - Compressing high-resolution MP4 recordings to fit email attachment limits or messaging app constraints. - Preparing MP4 or WebM background videos for websites to minimize page load times. - Batch-optimizing video archives to free up server storage space without losing noticeable visual quality. ## Frequently asked questions ### What video formats does the optimizer support? You can upload any standard video file, and export the optimized result as MP4, WebM, MKV, AVI, or MOV. ### What does the 'Web Streaming Optimized' option do? It restructures the video container for a fast start, allowing the video to begin playing in a web browser before it is fully downloaded. ### How does the custom CRF option work? Constant Rate Factor (CRF) controls video quality. Lower values yield higher quality but larger files, while higher values reduce size at the cost of quality. ### Is there a file size limit for uploads? Yes, the tool supports video file uploads up to 500 MB. ### Does optimizing a video remove its metadata? Yes, if you enable the 'Remove Metadata' option, it strips non-essential data like camera details and GPS tags to further reduce file size. ## Related tools - [Batch Video Compressor](https://elysiatools.com/en/tools/video-batch-compress): Compress multiple video files by reducing file size while maintaining quality using CRF, resolution scaling, and codec optimization - [Video Compressor](https://elysiatools.com/en/tools/video-compressor): Compress video files by reducing file size while maintaining quality using CRF, resolution scaling, and codec optimization - [Video to GIF Optimized](https://elysiatools.com/en/tools/video-to-gif-optimized): Convert videos to optimized GIF format with advanced compression settings - [Batch Video Converter](https://elysiatools.com/en/tools/video-batch-converter): Convert multiple video files between different formats like MP4, WebM, MKV, AVI, MOV with quality settings and batch processing - [Video Chroma Key](https://elysiatools.com/en/tools/video-chroma-key): Remove green screen or any colored background from video and replace with another video - [Video Stabilizer](https://elysiatools.com/en/tools/video-stabilize): Reduce camera shake and stabilize video footage using vidstab for professional quality results - [Optimize AVIF](https://elysiatools.com/en/tools/avif-to-optimized-avif): Optimize AVIF images for better compression and performance while maintaining visual quality - [Optimize GIF](https://elysiatools.com/en/tools/gif-to-optimized-gif): Optimize GIF images with advanced compression techniques while maintaining visual quality ## Samples - [Video Samples](https://elysiatools.com/en/samples/video-samples): Sample video files in different formats and orientations - [Video AV1 Samples](https://elysiatools.com/en/samples/video-av1-samples): Sample video files encoded in AV1 format - [Video H.264 Samples](https://elysiatools.com/en/samples/video-h264-samples): Sample video files encoded in H.264 (AVC) format - [Video H.265 Samples](https://elysiatools.com/en/samples/video-h265-samples): Sample video files encoded in H.265 (HEVC) format ## Related content - [Video Container Conversion with Deliberate Transcode Control](https://elysiatools.com/en/hubs/video-container-conversion-and-transcode-control): Convert footage between MP4, AVI, FLV, MKV, MOV, and WebM containers, keep CRF and bitrate decisions under control during the re-encode, and batch a whole library under one recorded configuration.
