Compress MP4 to 8 MB
Shrink MP4 videos to under 8 MB so you can drop them into Discord's free-tier uploader, Slack DMs, or tight email attachments. Runs entirely in your browser.
Compress MP4 to 10 MB
Compress MP4 videos to under 10 MB for email, Discord Nitro Classic, and chat apps that cap short video uploads. Private, browser-based, no signup.
Compress MP4 to 25 MB
Reduce MP4 videos to under 25 MB for Gmail attachments, Discord Nitro, and most corporate email systems. Fully client-side, no uploads.
Compress Video for WhatsApp
Shrink videos to fit WhatsApp's 16 MB sharing sweet spot and the 30-second Status limit. Private, free, and runs 100% in your browser.
Compress Video for Discord
Shrink any clip to fit under Discord's 10 MB free upload cap — no Nitro needed. Private, free, and runs 100% in your browser.
Compress Video for Email
Shrink any video to about 12 MB so it sends as a real attachment through Gmail and Outlook — not a Google Drive link. That extra headroom absorbs the ~33% Base64 overhead email adds, so it still clears the recipient's 20-25 MB cap. Free, private, and runs 100% in your browser.
Compress Video for iMessage
Shrink any clip under iMessage's ~100 MB ceiling so it sends as a sharp inline video — not an expiring iCloud link or a stalled blue send bar. Private, free, and 100% in your browser.
Compress Video for Slack
Shrink clips to a courteous ~10 MB so they upload in seconds and play inline on the first click for the whole channel. Slack streams your exact upload and never re-compresses it — so a smaller file is simply faster for everyone. Private, free, and runs 100% in your browser.
