Free Online Video Compressor

"In six years of editing—from phone clips to Fortune 500 brands—I've learned one thing: the tool doesn't matter if you can't hit 'send.' A compressor that gets your file under Discord's 10 MB limit without killing the story is worth more than any $2,000 plugin." — Ethan Brooks, Video Editor & Motion Designer

How to Compress Video Online in 3 Simple Steps

For batch jobs, repeat the upload for each file; the queue processes them one by one.

Compress Video to 10 MB, 8 MB, or Any Target Size

Our 10 MB video compressor gives you a slider to set your desired file size—down to the megabyte. The tool auto-adjusts bitrate, resolution, and codec settings to hit that number without manual trial-and-error.

Perfect for:

• Discord (non-Nitro: 10 MB max per file; source: Discord Support article "File Attachments FAQ", Discord Help Center, 2024–2025)
• Email (Gmail 25 MB per message per Google Workspace/Gmail Help 2025; Outlook ~20–34 MB depending on service—Outlook.com 34 MB, Exchange/Office 365 standard 20 MB per Microsoft Support 2025)
• Quick shares where bandwidth matters more than 4K glory

You get a smaller file size with predictable compressed video size and full control over quality trade-offs.

No guessing. No re-uploads.

Benchmark: How We Compare to Competitors (Q3 2025)

We tested our compressor head-to-head against leading online services using a standardized 1-minute 1080p 30fps H.264 clip (original size: 180 MB). Here's how we stack up.

Test Configuration:

• Source: 1-minute talking-head 1080p 30fps H.264, 180 MB
• Target: 10 MB output
• Date: August 2025
• Hardware: Standard cloud VM (4 vCPU, 8GB RAM)

Methodology: Three independent reviewers rated quality on a 5-point scale (5 = indistinguishable from source). Size accuracy calculated as (actual - target)/target × 100%. We update these benchmarks quarterly.

"The compressor nailed the 10 MB target within 2% and processed 16% faster than the nearest competitor—critical when you're on deadline." — Internal QA Report, August 2025

Top Free Online Video Compressors: Detailed Reviews

More Than Compression: Edit Before You Shrink

Before you compress, polish your clip with our built-in video editor. Here's what you can do:

• Trim & Cut

  Remove dead air, awkward pauses, or out-takes. Every second you delete = instant file-size drop.

• Crop

  Reframe to 16:9, 9:16, or 1:1 for platform specs.

• Rotate & Flip

  Fix phone orientation mistakes in one click.

• Merge

  Stitch multiple clips into a single export, then compress the whole thing.

• Add Music

  Layer background tracks, adjust volume, fade in/out.

• Add Text

  Overlay titles, captions, or burned-in subtitles for accessibility.

• Video Watermark

  Protect your work with logo overlays (position/opacity controls).

• Blur Video

  Obscure faces, license plates, or sensitive info with mask-based blur.

• Change Video Speed

  Create time-lapses (2×–4×) or slow-motion (0.25×–0.5×) before compressing.

• Video Enhancer

  Auto-denoise and sharpen for cleaner detail before bitrate reduction kicks in—resulting file stays small without looking muddy.

Each tweak stacks. Trim 20 seconds + crop to 1080p + denoise = smaller source = better compressed output at the same target size.

Bitrate Calculator: Hit Your Target Size First Try

Stop guessing. Enter your video duration, target file size, and audio bitrate—our calculator tells you exactly what video bitrate to use.

Example:

• Duration: 60 seconds
• Target size: 10 MB
• Audio: 128 kbps stereo

Calculation:

Video bitrate ≈ (10 MB × 8 - 128 kbps × 60 sec / 1000) / 60 sec
             ≈ (80 - 7.68) / 60
             ≈ 1.2 Mbps

Set your encoder to ~1.2 Mbps video bitrate and you'll land within 2% of 10 MB.

"This calculator saved me hours of trial-and-error exports. I punched in my numbers and the first render hit 9.9 MB—perfect for Discord." — Sarah M., Content Creator

Support for All Major Video Formats

We handle popular video formats and major video formats out of the box:

• MP4

  H.264/H.265/AV1

• MOV

  QuickTime, ProRes-friendly

• MKV

  Multi-track archives

• AVI

  Legacy Windows workflows

• WEBM

  VP9/AV1 for web streaming

The tool auto-detects your video format and file type, then optimizes codec settings. You don't need to convert first—just upload and compress.

Why Our Video Compressor Is the Best Choice

Perfect for YouTube, TikTok, Social Media & Mobile

Prep YouTube video and TikTok videos under platform limits—faster uploads, no server re-encoding that kills your grade. For Discord (10 MB non-Nitro), hit the 8 MB preset. For email (Gmail 25 MB, Outlook ~20 MB), compress to 20–22 MB to stay safe.

As an iOS video compressor (works in Safari) and general mobile compress videos tool, our service runs in any browser—no App Store download, no Android APK hunt. Just open, upload, compress, share video from your phone's camera roll.

How to Choose Optimal Compression Settings

Output Quality vs. File Size

Start with your target file size. If the preview shows blocky artifacts (especially in fast motion), bump bitrate +1–2 Mbps or reduce compression level. If file size is still over, lower resolution (1080p → 720p) before lowering bitrate further.

Rule of thumb: Resolution cuts file size dramatically; bitrate fine-tunes quality within that resolution.

What Is Bitrate and How Does It Affect Results?

Bitrate = bits per second (e.g., 8 Mbps = 8 million bits/sec). Higher bitrate = more data to describe each frame = better detail, especially in motion.

Static scenes (talking head, slideshow) compress easily—low bitrate works fine. Dynamic scenes (sports, action, pans) need higher bitrate to avoid blur/blocking.

CBR (Constant Bit Rate): Sends the same number of bits per second, no matter the scene. Predictable bandwidth for live streams, but wastes bits on easy scenes and starves complex ones.

VBR (Variable Bit Rate): Allocates more bits to complex scenes, fewer to simple ones. Better average quality for the same file size. Recommended for offline files (YouTube uploads, archived footage).

Resolution Recommendations by Platform

• YouTube: 1080p (1920×1080) is the sweet spot for most creators. 4K if you have the bandwidth and audience.
• Instagram Reels / TikTok: 1080×1920 (9:16 vertical). Don't go lower—platforms auto-crop, and 720p looks soft.
• Email: If you're hitting size limits, drop to 720p (1280×720) at 3–4 Mbps. Keeps file under 20 MB for 1–2 minute clips.

Codec Showdown: H.264 (AVC) vs. H.265 (HEVC)

Why HEVC saves space: Advanced motion compensation, larger coding tree units. Result: ~50% bitrate reduction for equivalent visual quality.

Why H.264 still wins for web: Every device decodes it; no licensing headaches for browsers; hardware acceleration everywhere. HEVC needs fallback or explicit browser support.

Bottom line: Use H.264 for broadest reach. Use HEVC if your audience is modern (iPhone 7+, recent Android) and you need the smallest file for 4K.
