Choose one video, up to 10 minutes and about 2 GB. Compression can reduce picture quality. If your file is already small enough, you can keep the original.
Email services usually allow about 25 MB per message, but a video grows by about a third when it’s attached, so 18 MB is a safe size for email. It also fits Discord’s free limit. Limits change, so check the app if you’re close.
10 MB means 10 million bytes, the way most apps measure file limits. We check the finished file and try once more if needed. If it’s still too big, you’ll see its size before you download.

Questions
How small will my video be?
Smaller file aims for about half the original size. Under 18 MB and Under 10 MB aim for those sizes: we check the finished file and try once more if needed. If it’s still too big, you see its size before you download, and you can choose a lower quality to make it fit.
Will it lose quality?
Some. Compressing makes a new MP4 at up to 720p and 30 frames per second, and smaller sizes look blurrier. A short video keeps more detail at the same size, so trim it first if you only need part of it.
What size fits email?
Email services usually allow about 25 MB, but an attached video grows by about a third, so Under 18 MB is the safe choice. Limits change, so check your email service if you’re close.
Which videos can I compress?
One video at a time, up to 10 minutes and about 2 GB: the MP4 and MOV videos phones and cameras make, including iPhone HEVC. You always get an MP4 with H.264 picture and AAC sound.
Does Compress Video work on iPhone and Android?
Yes, in Safari on iPhone and iPad and in Chrome on Android, kept up to date. iPhones need iOS 26 or later. If your phone or browser can’t do a video, you’ll see a message instead of a broken file.
Why is it slow on my phone?
Your phone does the work itself instead of sending the video to a server, so the time depends on your phone and the video’s length. Making a new video can take several minutes on a phone; as a guide, an iPhone 15 took about 5 minutes to merge a 9.6-minute video. Keep the page open until it’s done. Stop and edit lets you go back without losing your settings.
Is my video uploaded?
No. Your video is made on your phone or computer and never leaves it, so a big video doesn’t need a fast connection. We only collect anonymous usage counts and error reports, listed on the privacy page.
