Compress a video to attach in an email. Free, no upload, no signup. SammaPix shrinks your MP4 under the 25 MB Gmail and Outlook limit right in your browser.
Gmail, Outlook and most email providers cap attachments at 25 MB. Compress your clip to fit instead of fighting with cloud links.

MP4, MOV, WebM, MKV, AVI — shrink files by up to 80%
100% in your browser — your video never leaves your device · up to 500 MB
Gmail and Outlook both cap attachments at 25 MB. Larger files are usually offered as a cloud link instead. Compressing your video to 1080p under 25 MB lets you attach it directly so the recipient does not need to open a separate link.
Set the target size to 25 MB and keep the 1080p downscale on. SammaPix re-encodes locally and shows the estimated size live so you can confirm it fits before downloading.
No. Compression runs entirely in your browser with WebCodecs. The file never leaves your device.
Very long clips may not fit at a watchable quality. In that case, trim the video shorter rather than crushing the bitrate, which keeps the part you care about sharp.
