If you frequently work with large videos and want more control over the compression process, Video Converter Ultimate is a convenient desktop solution. It includes a video compressor and conversion tools that let you adjust output settings to reduce file size while keeping the video suitable for your intended use.
Unlike basic online compressors, desktop software is particularly useful when you need to process large files, customize output parameters, or compress multiple videos without repeatedly uploading them to a website.

Here is how to reduce video size without losing quality:

QuickTime Player is a built-in macOS application that can export videos at different resolutions. It's a convenient option if you want to reduce video size for free without downloading another application.
Although QuickTime Player doesn't offer a dedicated target-size compression slider, exporting a video at a lower resolution can help reduce its file size.
Here is how to compress video for free on Mac via QuickTime Player:
Step 1. Open QuickTime Player on your Mac.
Step 2. Click "File" > "Open File" and select the video you want to compress.
Step 3. Once the video opens, click "File" > "Export As".
Step 4. Choose an available resolution, such as 1080p, 720p, or 480p, depending on the source video and your macOS version.

Step 5. Select a filename and destination folder, then click "Save" to export the compressed version.
Step 6. Wait for the export to finish and check the resulting file size and playback quality.
VLC Media Player is best known as a free media player, but it also includes a conversion feature that can help you compress video for free. By choosing a more efficient output format or adjusting the video bitrate and resolution, you can make large files smaller.
VLC is a good choice if you already have it installed and don't want to pay for a separate video compressor.
Here is how to reduce video size for free on Windows using VLC:
Step 1. Open VLC Media Player on your computer.
Step 2. Click "Media" > "Convert/Save" on Windows.
Step 3. Click "Add" to import the video you want to compress, then select "Convert/Save".
Step 4. Under "Profile", select a suitable video format, such as "Video - H.264 + MP3 (MP4)", if available.
Step 5. Click the profile's settings or edit icon. Open the video codec settings and lower the bitrate or resolution if necessary.
Step 6. Choose the destination file and ensure that the filename includes the appropriate extension, such as .mp4.

HandBrake is a free, open-source video transcoder for Windows, Mac, and Linux. It is one of the most flexible choices for anyone who wants to compress MP4 video files or reduce the size of other supported video formats.
Unlike QuickTime Player, HandBrake provides detailed control over encoding quality, video dimensions, frame rate, and output format. It can also help you target a smaller file size, although the exact output size may vary.
Here is how to use HandBrake to reduce video size:
Step 1. Download and install HandBrake from its official website, then launch the program.
Step 2. Click "Open Source" to import the video you want to compress.
Step 3. Under the "Summary" tab, select "MP4" as the output format.
Step 4. Open the "Dimensions" tab and lower the resolution if needed, such as converting 4K to 1080p.
Step 5. Go to the "Video" tab and choose an encoder, such as H.264 or H.265 (HEVC).
Step 6. Adjust the "Constant Quality" setting. A higher RF value generally produces a smaller file with lower quality. Alternatively, use "Average Bitrate" to control file size more directly, if available.
Step 7. Choose the output folder and click "Start Encode" to begin compression.
Step 8. Once encoding finishes, check the output file size and video quality.
