iMovie Alternatives for Windows and Browser — Free Video Editing Tools

iMovie is free on Mac and iOS but does not exist for Windows, ChromeOS, or Linux. If you need to compress, crop, resize, change speed, merge, add subtitles, or extract audio from video — browser-based tools do all of these on any platform with no install.

Compress Video (iMovie Makes This Harder Than It Should Be)

In iMovie, there is no "compress" button. You export the project and choose a lower quality preset — but you cannot target a specific file size or bitrate. The result is often still too large for email or messaging.

A dedicated compressor lets you upload any video, choose a target (720p, 480p, or specific file size), and download the compressed result. A 200MB iPhone video typically compresses to 20-40MB at 720p.

• Video Compressor — precise size and quality control

Crop Video for Instagram, TikTok, or Square

iMovie crops video by applying a "Crop to Fill" effect and repositioning within a fixed 16:9 frame. Getting a 9:16 vertical crop for Instagram Reels or TikTok requires workarounds. Browser crop tools let you pick any aspect ratio directly.

• Crop Video — 16:9, 9:16, 1:1, 4:5, or custom crop
• Resize Video — change resolution without cropping

Change Video Speed

iMovie supports per-segment speed changes with a nice visual interface. If you only need to speed up or slow down an entire clip, the browser tool is faster — upload, set speed, download. No project setup required.

• Video Speed — 0.25x to 4x speed adjustment

Merge Multiple Clips

iMovie's timeline is great for arranging clips with transitions. If you just need to concatenate files — clip A followed by clip B — the browser tool joins them without opening a full editor.

• Merge Video — combine multiple video files into one

Add Subtitles

iMovie has "Titles" — text overlays with animations and effects. It does not support SRT subtitle files or timed captions. For burning proper subtitles into video (for social media, accessibility, or foreign language content), use a dedicated subtitle tool.

• Add Subtitles — burn SRT captions into video frames
• Speech to Text — generate transcript from audio to create SRT file

Extract Audio from Video

In iMovie: import video → right-click → detach audio → delete video → share as audio. Four steps. In a browser tool: upload video → click extract → download MP3. One step.

• Video to MP3 — extract audio instantly
• Audio Converter — convert between MP3, WAV, OGG, FLAC

When iMovie Is Still Better

• Multi-clip timeline editing — arranging clips, adding transitions, layering audio
• Color correction — adjusting exposure, contrast, saturation per clip
• Trailer templates — cinematic templates with placeholder shots
• Background music library — royalty-free tracks built in
• Per-segment speed changes — different speeds within one clip

For actual video editing (assembling a project from multiple clips), iMovie remains excellent and free on Apple devices. For individual tasks — compress, crop, convert, extract — browser tools are faster because you skip the project setup entirely.
