How to compress a video so you can email it
Email providers cap attachments at around 25MB (Gmail and Outlook both sit near there). A phone video blows past that in seconds. Here is how to shrink a clip to fit an email attachment in your browser — without uploading it to a third-party compressor.
Open fqfit →Know your provider’s limit
Gmail allows attachments up to 25MB; Outlook.com is similar; many corporate mail servers are stricter at 10MB. Set whichever number applies as your target. fqfit takes a custom MB value, so you can dial in exactly 25, 20, or 10.
Set the target and trim
Open fqfit, drop the video, and type your size limit (for example, 25). Trim to the part the recipient actually needs — a shorter clip fits the same size at higher quality. Downscaling to 720p helps a lot for phone footage shot at 4K.
Send it on the first try
fqfit fits the encode to your target and downloads a standard MP4 (H.264 + AAC) that plays everywhere — in the email preview, on a phone, on any desktop. No more bounce-backs for an attachment that is too large.
How to do it, step by step
- Open fqfit. Go to yarimati.com/fqfit — no signup or install.
- Drop your video. Drag the clip onto the page; it stays on your machine.
- Type your size limit. Enter a custom MB target, e.g. 25 for Gmail.
- Trim and downscale. Cut to the needed part; pick 720p for 4K phone footage.
- Compress and attach. Click Compress and save, then attach the downloaded MP4 to your email.
Compression happens in your browser via FFmpeg.wasm and WebCodecs. The video you are emailing never passes through fqfit — it stays on your machine until you attach it yourself.
Frequently asked questions
How big a video can I email?
Most providers cap attachments around 25MB (Gmail, Outlook). Compress the video to just under your provider’s limit, or use a custom lower target for stricter corporate mail servers.
What if my video is still too big after trimming?
Lower the target MB value and/or downscale to 720p or 480p in fqfit. For very long videos, a share link from a file tool may suit better than an attachment.
Is fqfit free?
Yes — free, no signup, no upload to a server.
