How it works

01

Browser-native

Squish uses FFmpeg compiled to WebAssembly. Your video is processed entirely by your own CPU — nothing ever leaves your device.

02

Pick your target

Choose a platform preset or manually set quality, resolution, output format, and exact file size.

03

Instant download

The compressed video is handed straight to your browser. No queues, no waiting, no account, and no server upload.

04

Realistic limits

Squish runs in browser memory (RAM). Use a desktop or newer 6GB+ RAM phone for best results; older 4GB phones may fail before compression because the engine itself needs RAM. Hard cap: 2GB.

Platform presets

Every platform has different file size limits. Squish knows them all.

𝕏
Twitter / X
≤ 512 MB · max 2:20
Keeps 720p so your video doesn't get double-compressed by Twitter's encoder.
💬
WhatsApp
≤ 16 MB
WhatsApp rejects videos over 16 MB. Squish compresses to 480p to fit comfortably.
◎
Instagram Reels
≤ 50 MB · 1080p
Keeps vertical clips crisp while avoiding giant camera-roll exports.
▯
iPhone clips
1080p · share-ready MP4
Turns large camera videos into lighter H.264 files that preview and share cleanly.
🎮
Discord
≤ 8 MB (free tier)
Discord free tier caps at 8 MB. Squish hits that target precisely with bitrate-controlled encoding.
📧
Email
≤ 5 MB
Most email providers block attachments over 5–10 MB. Squish makes your video email-safe.

Questions answered

Is Squish completely free?

Yes — free with no account, no subscription, no watermarks, and no upload. Because it runs purely in your browser, our server costs are nearly zero. We may introduce a pro version for teams later, but this core tool stays free forever.

Does my video get uploaded to a server?

Never. Squish runs entirely in your browser using WebAssembly. Your files are never transmitted over the internet — they stay on your device the whole time.

How much can Squish compress a video?

Typically 50–90% depending on the original. Phone footage is often over-encoded and compresses dramatically. At Tiny quality + 480p you'll get the smallest file possible.

Will the video lose quality?

At Excellent (CRF 18) quality loss is imperceptible. At Balanced (CRF 24) it's barely noticeable. For social media, Balanced is the sweet spot.

What browsers does Squish work in?

Chrome, Edge, Firefox, Brave and Safari. Chrome and Edge have the fastest WebAssembly engines and give the best compression speed.

Is there a file size limit?

Squish blocks files over 2 GB. Use a desktop or newer 6GB+ RAM phone for best results. Older 4GB phones may fail before compression, even with small files.
