How to compress video
- Sign in — 500 free credits a month.
- Drop the video, pick a size.
- Run Compress and download the MP4.
What happens to your file
The video is re-encoded with H.264 at a bitrate chosen for the mode, audio as AAC, and the file is written with the index at the front so it starts playing before it has fully downloaded.
Resolution is kept unless "small" is chosen, which also caps it at 720p. A phone recording at 4K compresses by five to ten times.
Questions
How do I make an MP4 smaller?
Drop it here and pick a mode. Two things shrink a video: encoding it at a lower bitrate, and reducing the resolution. The "small" mode does both, capping the picture at 720p, which is where most of the saving comes from on a phone recording.
Which mode for WhatsApp, email or a message?
"Small". It targets the size limits messaging apps and mail servers actually enforce, which are usually somewhere between 16 and 25 MB.
How much smaller will it get?
A 4K phone recording typically compresses by five to ten times, because phones record at bitrates far above what the picture needs. Something already compressed once — a download, a clip from a messaging app — has much less to give up.
Will it lose quality?
Some, by definition. At the default mode the difference is hard to see at normal viewing distance. At "small" you will notice it on fast motion and in dark scenes, which is the trade for a file that will actually send.
Would trimming help more than compressing?
Often, yes, and it costs nothing in quality. Half the length is half the file. If the clip has thirty seconds nobody needs, trim it first and you may not need to compress at all.
What does it cost?
Two credits per megabyte of input, so a 100 MB clip is 200 credits, and the first 500 credits each month are free. Video is priced by input size because that is what the work scales with.
Do it once, not on every form
Fixing a file here means downloading it and going back to the form. The Fylane extension does this work inside the form instead, on the file you already have.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
