How to Attach Long Video in Gmail (Over 25MB)

Gmail has a 25MB attachment limit, which means most videos — even short ones — are too large to attach directly. Whether you’re on desktop or trying to send a video in Gmail more than 25MB using your phone, you’ll hit a wall pretty quickly. The good news is there are a few reliable workarounds to get your video delivered without hassle.

Here are the 3 best options:

Option 1: Compress the Video with TinyFile

If you want to keep things simple and send the video as an actual email attachment (rather than a link), compressing it first is your best bet.

TinyFile is a video compressor app that intelligently calculates the correct compression settings and resolution needed to bring your video size down to the limit required for email attachments. Instead of manually guessing bitrate or resolution settings, TinyFile does the math for you — you just set your target file size, and it handles the rest while preserving as much quality as possible.

How to use it:

1. Download TinyFile on your phone or desktop.
2. Import the video you want to send.
3. Set your target file size to under 25MB.
4. Let TinyFile automatically calculate and apply the optimal compression settings.
5. Save the compressed video, then attach it to your Gmail as normal.

This is the best option when the recipient needs the video as a direct attachment rather than a link.

Option 2: Share via Google Drive

Google Drive is built right into Gmail, making this one of the easiest options — especially on mobile.

How to use it:

1. Open Google Drive and upload your video (tap + New > File Upload).
2. Once uploaded, right-click the file (or tap the three dots on mobile) and select Share or Copy link.
3. Set the sharing permission to “Anyone with the link can view.”
4. Open Gmail and compose your email.
5. Tap the Google Drive icon in the compose toolbar (or paste the link directly into the email body).
6. Send — your recipient will get a link to stream or download the video.

Gmail will often prompt you automatically to use Google Drive when it detects an attachment over 25MB, so this process can be nearly seamless.

Option 3: Share via Smash

Smash is a free file transfer service with no file size limit, making it a great option for large or high-quality videos you don’t want to compress.

How to use it:

1. Go to fromsmash.com on your browser (or download the Smash app on your phone).
2. Upload your video by dragging and dropping it or selecting it from your files.
3. Once uploaded, Smash will generate a unique download link.
4. Copy that link and paste it into the body of your Gmail message.
5. Send the email — your recipient clicks the link to download the video directly.

Smash links typically stay active for 14 days on the free plan, which is plenty of time for most use cases.
