No sign-up. No upload. No size limit.
Nothing is uploaded — the file is compressed on your device.
Attachment limits by provider
All checked September 2026. Gmail allows 25 MB of attachments per message and turns anything larger into a Google Drive link (Gmail Help). Outlook.com allows 25 MB per attached file (Microsoft Support). Yahoo Mail allows 25 MB for all attachments in one message together (Yahoo Help). iCloud Mail's message limit is 20 MB, or up to 5 GB with Mail Drop turned on (Apple Support).
Work accounts follow whatever the administrator set, and Outlook's default for Exchange accounts is 10 MB (Microsoft Support). Exchange counts the encoded message, which Microsoft says is about 33% larger than the files in it (Microsoft Learn). Under a 10 MB limit, that leaves room for a video of about 7 MB. The recipient's server has its own limit, which you cannot see.
How this page sets the size
The target starts at 25 MB, and the compressor aims 1.5% under the size you set. If the clip is too long for 25 MB at its current screen size, the panel picks a lower resolution itself and shows "Resolution set to W × H to reach this size." For a limit other than 25 MB, click the After size (the pencil icon) and type the number, for example 20 for iCloud Mail.
The compression runs in your browser with your device's video encoder. The result is written to disk as it is produced, so a recording of several GB works, and nothing is sent anywhere before you attach it yourself.
Fitting more into the attachment
Cut what the recipient does not need: Trim Video ↗ removes the first seconds of a screen recording before you compress. In Advanced, Audio at 64 kbps leaves more room for the picture when the sound is only speech, and Remove audio gives the whole size to the picture. MP4 (H.264) is the default format. If one frame is enough, Video to Image ↗ saves it as a picture that shows inside the email.
Frequently asked questions
Which size should I type for my provider?
25 for Gmail, Outlook.com and Yahoo Mail. 20 for iCloud Mail without Mail Drop (both checked September 2026). For a work account, ask the administrator for the limit and aim at about three quarters of it to allow for encoding.
Gmail turned my video into a Drive link. Why?
The attachments in that message added up to more than 25 MB. Remove other attachments, or type 24 as the size and compress again.
Does the recipient need this site?
No. The result is an ordinary video file.
Is my video uploaded to compress it?
No. It is read and compressed on your device, and the original file is not changed. See the privacy policy.
