Video too large to send from iPhone

Written by Ahmet Karaca, developer of SnapSlim at Akaya Labs · Updated: October 31, 2026

The limit usually belongs to the app you're sending through, not to your iPhone. So first check whether you can send the video another way without losing quality. Compress it only when that doesn't work.

Limits by service

Figures come from each provider's help pages, checked in October 2026. They can change, so see the sources below.

Send it without shrinking

Compress it with SnapSlim

SnapSlim is my app, so weigh this section accordingly. It's useful here because it shows an estimated size before you start, so you can pick an option under the limit. The video is compressed on the device and isn't uploaded.

  1. Open SnapSlim, tap Video Compress and choose the video.
  2. Compare the estimated sizes of Low, Medium and High, and pick one under your limit.
  3. Tap Compress.
  4. Tap Share and choose the app you want to send it with.

If it's still too large

For long videos, sending a link usually works better than compressing further. Upload to iCloud Drive or Google Drive and share the link, but keep in mind that this does put the file on that service.

  1. Trim it: in the Photos app, open the video, tap Edit and drag the ends of the timeline. Then compress the shorter copy.
  2. Choose Low (720p), which gives the smallest file.
  3. Remove the audio if you don't need it. In SnapSlim this is a Premium feature.

Compress on your iPhone

SnapSlim is free to download and includes 5 operations a day, with ads. Your files are compressed on the device and never uploaded.
