How to compress video online
To compress a video, choose your video file, pick a compression goal like Gmail, Discord, WhatsApp, social media or Custom, then download the smaller MP4. On Remove Audio, compression runs locally in your browser using WebAssembly, so your video is not uploaded to a server. You can batch compress up to 20 videos, up to 1 GB each, for free and without watermarks.
- Choose your videos
- Pick a compression goal
- Download smaller MP4 files
Why use this free video compressor?
Most compressors make you upload your file to a server and wait twice, once up and once down. This one runs in your browser instead, so it is private, instant to start and free.
Batch compress up to 20 videos
Compress one video or add up to 20 videos at once. The same preset can apply to every file, and each video is processed locally in your browser so you can download files one by one or together when the batch is done.
Up to 1 GB per video
Large videos are welcome. You can compress files up to 1 GB each without sending them to a server, making the tool useful for phone videos, screen recordings, client clips, course videos, webinars and social media exports.
100% local processing
Your videos stay on your device. Compression happens inside your browser using WebAssembly based video processing, so the file content is not uploaded, stored or inspected by Remove Audio.
No watermark, no signup
Download clean compressed videos with no watermark, no forced outro and no account required.
Compress for real upload limits
Choose presets for Gmail, Discord, WhatsApp, website uploads and social media instead of guessing the right settings. Custom mode lets you enter a target size in MB when you need a specific file limit.
Simple controls, advanced when needed
Most users only need one dropdown. When you want more control, Custom mode gives you target size, quality balance, resolution and audio options without turning the tool into complicated editing software.
How to compress a video in three steps
Three steps, all in your browser.
Choose your videos
Drop MP4, MOV, MKV, AVI or WebM files into the box, or browse your device. You can add up to 20 videos at once, with files up to 1 GB each.
Pick where the video needs to fit
Use Balanced for everyday compression, or choose Gmail, Discord, WhatsApp, Website upload, Social media, Smallest file or Custom target size.
Download the smaller video
Your browser compresses the video locally and creates a smaller MP4. Download each result individually or save the full batch when compression is finished.
What goes in, what comes out
| Input | Output |
|---|---|
| iPhone 4K MOV (390 MB) | 1080p MP4, roughly 60 to 90 MB |
| 1080p screen recording (184 MB) | Under 25 MB with the Gmail preset |
| Gameplay clip (45 MB) | Under 10 MB with the Discord preset |
| Any supported video | H.264 MP4 that plays everywhere |
Choose the easiest compression preset
Every preset answers one question: where does this video need to go? Platform limits change over time, so the target presets aim to fit under the cap rather than promise it.
| Option | Best for | What it does |
|---|---|---|
| Balanced | Everyday sharing | Good quality with strong size reduction |
| Gmail / Email | Email attachments | Tries to keep each video under 25 MB |
| Discord | Free Discord uploads | Tries to keep each video under 10 MB |
| Chat sharing | Uses WhatsApp friendly compression around 720p and under 100 MB | |
| Website upload | Forms, CMS, portals | Creates a smaller MP4 with safe compatibility |
| Social media | Instagram, TikTok, YouTube, LinkedIn | Keeps good visual quality for posting |
| Smallest file | Maximum reduction | Strong compression when size matters most |
| Custom | Exact control | Choose target size, quality balance, resolution and audio |
Presets try to fit common limits, but the final size depends on video length, motion, resolution and how compressed the original file already is.
Custom compression without complicated settings
Need a specific file size? Choose Custom and enter a target size in MB. Then adjust the quality balance between Smaller file and Better quality. For extra control, open Advanced settings to choose the output resolution or decide what happens to the audio.
Target size: try to fit the video under a specific MB limit
Quality balance: move toward smaller file or better quality
Resolution: Auto, keep original, 1080p, 720p or 480p
Audio: compress audio, keep original audio or remove audio
Smaller files usually require more compression. For the best looking result, start with Balanced or Custom, then use Compress more or Try better quality after seeing the output.
What actually changes when you compress video?
A video file is mostly made of video data, audio data and metadata. Compression reduces the amount of data needed to store the video. The tool can lower bitrate, adjust resolution, compress audio or remove audio when you choose that option. The result is a smaller MP4 that is easier to send, upload, store and share.
Original video
- 🎬 Video stream
- 🔊 Audio track
- 📄 Metadata
Compressed MP4
- 🎬 Smaller video stream
- 🔊 Optimized or removed audio
- 📦 Smaller file
Video compression is a tradeoff: smaller files can mean lower quality. The goal is to reduce file size while keeping the video looking good for where it will be used.
Your videos are not uploaded. Ever.
Most online video compressors upload your file to a server before processing it. Remove Audio works differently. Your video is opened and compressed locally in your browser using WebAssembly based processing, so the file stays on your device.
This is especially useful for family videos, client work, business recordings, school projects, job applications, private screen recordings and any file you do not want to upload to a third party server.
What that means in practice
- We do not receive your videos
- We do not store your videos
- We do not inspect your files
- You can compress private clips locally
- Processing speed depends on your device and browser
What people compress videos for
Most people compress a video for one reason: it is too big for where they want to send it. These are the walls this tool clears.
Compress video for Gmail
Make a video small enough to send as an email attachment instead of turning it into a cloud link. The Gmail preset aims to fit under the 25 MB attachment limit.
Compress video for Discord
Reduce video size for Discord chats, servers and communities, especially when you need to fit under free upload limits. The Discord preset aims for under 10 MB.
Compress video for WhatsApp
Create a smaller, chat friendly MP4 that is easier to send from your phone or desktop, around 720p so WhatsApp does not degrade it further.
Compress video for website upload
Job portals, school platforms, CMS forms and client portals often reject large videos. Compress before uploading so the file goes through on the first try.
Compress video for social media
Make videos easier to post on Instagram, TikTok, YouTube Shorts, Facebook, X or LinkedIn while keeping good visual quality.
Compress iPhone videos
Phone videos can become huge very quickly. Compress MOV or MP4 clips before sending or storing them, without uploading anything.
Compress screen recordings
Long screen recordings from tutorials, demos, Loom style clips or webinars are much easier to share after compression.
Save storage space
Reduce large local videos before archiving, sharing or backing them up, then delete the bulky originals.
Browser based vs upload based video compressors
| Feature | Remove Audio | Typical upload based compressor |
|---|---|---|
| Upload required | No, files stay on your device | Usually yes |
| Batch compression | Up to 20 videos | Often limited or paid |
| Max file size | Up to 1 GB each | Depends on plan or server limit |
| Watermark | No | Sometimes |
| Signup | No | Sometimes |
| Private videos | Better, nothing leaves your browser | Depends on provider |
| Processing cost | Uses your device | Uses their servers |
| Very large files | Depends on device memory | Depends on upload limit and plan |
| Advanced options | Simple Custom mode | Sometimes more technical |
Fair note: because compression runs locally, large 4K videos can take time and may use a lot of browser memory. For very large files, a desktop browser is usually better than a phone.
Smaller without looking worse
Compression is a tradeoff, but a well chosen one is hard to notice. The presets aim for the sweet spot where the file shrinks a lot before the picture visibly suffers.
Modern H.264 encoding
Every preset re-encodes with H.264 at quality first settings, capping bitrate only when a size target demands it. Many everyday videos, like phone clips, screen recordings and social exports, can shrink a lot before quality loss becomes obvious.
You keep the last word
Not happy with the result? Try better quality and Compress more re-run the job with the tradeoff shifted, and Custom gives you an exact target size, resolution and audio handling.
Best for quick, private video compression
| Great fit | Not ideal |
|---|---|
| Compressing videos without upload | Professional color grading or studio mastering |
| Batch compressing up to 20 files | Huge multi hour 4K videos on weak devices |
| Making videos smaller for Gmail, Discord or WhatsApp | Exact broadcast encoding workflows |
| Reducing iPhone videos and screen recordings | Downloading videos from links |
| Private client, school or business files | Files you do not own or have permission to process |
| Simple presets instead of technical settings | Frame accurate professional editing suites |
