How to Compress a Video

Reduce your video file size in minutes — no account needed, no uploads to any server. Everything runs locally in your browser.

Step 1: Select Your Video

Drag and drop your video file onto the drop zone, or click Browse to open the file picker. Most common formats are supported, including MP4, MOV, MKV, AVI, and WebM.

Step 2: Choose How to Compress

You have two ways to control the output size:

Quick Presets

Pick a preset based on your priority:

  • Low — Smallest possible file. Some quality loss, but drastically reduced size. Great for messaging apps or archiving old footage.
  • Balanced — The sweet spot between size and quality. Recommended for most use cases: social media, email, or general sharing.
  • High — Minimal quality loss with moderate compression. Best when visual quality matters, such as presentations or client work.

Target File Size

Need to hit a specific limit? Type in a target size in MB, or tap one of the quick-select buttons for common platforms:

Platform Limit
LINE 10 MB
Discord 8 MB
Gmail 25 MB
Messenger 20 MB
Telegram 50 MB
Twitter/X 16 MB
Email 100 MB

When a target size is set, presets are disabled — the compressor automatically adjusts quality to meet your limit.

Step 3: Compress

Click Compress Now. A progress bar shows you how far along the process is. Compression is done entirely in your browser using FFmpeg via WebAssembly — your video never leaves your device.

Keep the tab open while compression is running. Switching tabs or minimising the browser may pause or interrupt the process.

Step 4: Download

Once finished, you'll see the original size, compressed size, and space saved. Click Download to save the compressed MP4 to your device.

Tips for Best Results

  • Short clips compress fastest. Very long videos (30 min+) may take several minutes depending on your device.
  • Already compressed? If a video was previously encoded at low bitrate, further compression may not reduce the size much.
  • Target size is an estimate. The actual output may vary slightly depending on the video's content and complexity.
  • Screen recordings and animation tend to compress extremely well — often 70–90% size reduction.
  • Your files are never uploaded. All processing is done on-device, so your videos stay completely private.

Frequently Asked Questions

How do I compress a video for LINE, Discord or Telegram?
Drop your video into Squishyfile, then click one of the quick-pick size tags (LINE 10 MB, Discord 8 MB, Gmail 25 MB, Telegram 50 MB…) or type your own target in MB. The compressor automatically calculates the bitrate needed to hit that size.
Will compression reduce video quality?
It depends on how much you compress. The "Balanced" preset keeps visually acceptable quality while cutting file size significantly. "High Quality" preserves more detail. If you set a very tight target size on a long video, some quality loss is unavoidable — that's true of any compressor.
What video formats are supported?
Squishyfile supports MP4, MOV, AVI, WebM and MKV for input. The compressed output is delivered as MP4, which is compatible with virtually all devices and platforms.
Can I compress 4K videos?
4K compression runs entirely in your browser with no server-side limits. For stable performance we recommend keeping files under 2 GB. Large 4K files may take a couple of minutes depending on your device.
Can I compress a video on my phone without installing an app?
Yes. Open this page in your iPhone or Android browser — no app needed. Select your video, choose a preset or target size, and download the compressed file in seconds.
Why is my compressed file the same size as the original?
This can happen if the source video is already heavily compressed (e.g. a video downloaded from YouTube or TikTok). Re-compressing an already-compressed file yields little to no size reduction. In that case, try a lower quality preset or a smaller target size.
