Free online video compressor — private by design
ShrinkMyVid is a free online video compressor that helps you reduce video file size so you can email, message, or upload your clips without hitting an attachment limit. Unlike most tools, every step happens locally on your device — your video is never uploaded to a server, so it stays completely private.
Compress video for email without the 25 MB headache
Gmail, Outlook, and iCloud Mail cap attachments at around 20–25 MB, and chat apps are often stricter. ShrinkMyVid lets you pick a target size and automatically works out the right bitrate and resolution to compress your video under 25 MB — or 10 MB for messaging — while keeping it as watchable as possible.
Works with the formats you already have
Drop in just about anything and get back a universally compatible MP4:
- Compress MP4 from phones, cameras, and screen recordings
- Convert and shrink MOV, MKV, AVI, and WebM
- Output is always H.264 MP4 — it plays on every device and email client
Why client-side compression matters
Because ShrinkMyVid runs in WebAssembly inside your browser, there is no upload wait, no queue, and no privacy risk. Your files never touch our servers — there are no servers in the loop at all. That makes it faster for large videos and safe for sensitive footage, and it even keeps working after you go offline.
Frequently asked questions
Is ShrinkMyVid free to use?
Yes. ShrinkMyVid is completely free with no account, no sign-up, and no watermarks. Compress as many videos as you like.
Do my videos get uploaded to a server?
No. All compression happens locally in your browser using WebAssembly. Your video never leaves your device and is never uploaded anywhere, which makes it completely private.
How do I get a video under 25 MB to email it?
Drop your video in, choose the Email (25 MB) preset, and click Shrink. ShrinkMyVid automatically calculates the right bitrate and resolution to land your file under the 25 MB Gmail and Outlook attachment limit.
What video formats can I compress?
You can drop in MP4, MOV, WebM, MKV, AVI, and most other common formats. The compressed result is always an MP4 (H.264), which plays on virtually every phone, computer, and email client.
Will compressing my video reduce the quality?
Compression trades a little quality for a much smaller file. ShrinkMyVid shows you the original and the compressed video side by side so you can compare before downloading, and you can choose a larger target size for higher quality.
Is there a file size or length limit?
There is no hard limit. Because processing happens on your own device, very large or long videos depend on your computer or phone's available memory rather than any server cap.
Does it work on my phone?
Yes. ShrinkMyVid runs in any modern browser, including Safari on iPhone and Chrome on Android. No app install is required.
Is ShrinkMyVid safe and private?
Yes. Since nothing is ever uploaded, there is no risk of your private videos sitting on someone else's server. The tool is privacy-first by design and works even after you go offline.
