Ultimate
Media Compressor

Our custom compression tool lets you specify the exact file size you need (in KB or MB) and dimensions in pixels. The tool will automatically adjust the compression quality to meet your target size while maintaining the dimensions you specify. It works by intelligently adjusting the compression level through multiple iterations to get as close as possible to your target size.

By default, the tool will use your original dimensions unless you specify different width and height values. If you enter custom dimensions, the tool will resize your image/video to those exact dimensions before applying compression. For best results, maintain the original aspect ratio to avoid distortion.

The minimum target size is 10KB. However, the actual achievable size depends on your original file's content and dimensions. For very small target sizes, the tool may not be able to reach exactly your target while maintaining acceptable quality, but it will get as close as possible.

Yes! The custom compression works for both images and videos. For videos, you can specify target size and dimensions, and the tool will adjust bitrate and other parameters to meet your requirements. Note that video compression may take longer depending on the length and original quality.

The tool typically gets within 5% of your target size. For example, if you specify 200KB, the result will usually be between 190-210KB. The accuracy depends on the original file and the compression algorithm's ability to reduce size without significant quality loss.

For images: JPEG, PNG, and WEBP formats support custom size targeting. For videos: MP4, WEBM, and MOV formats are supported. GIFs can be compressed but with less precise size control due to their unique compression characteristics.

There's no hard limit, but very large files (over 100MB) may take longer to process and could cause performance issues on older devices. For best results with large files, we recommend using a desktop computer with sufficient memory.
