How to Send Large Video Files (From a Phone, by WhatsApp or Email)

By Thiago · Updated October 3, 2026 · 4 min read

You recorded a great video, try to send it, and the app says it is too big, cuts it, or turns it into a blurry mess. There are two ways out: make the video smaller, or pick a way of sending that accepts big files. Which one is right depends on who receives it and how good it needs to look.

First question: does it need to stay in full quality?

Most videos are watched once on a phone screen. For those, a smaller copy at 720p looks just as good and arrives in seconds. But if the person is going to edit the video, print frames from it or show it on a big TV, send the original and choose a route without size problems. The table shows what each route allows.

The WhatsApp and Mail Drop figures come from the official WhatsApp and Apple help pages. Email limits depend on the service and account: personal Gmail accounts allow 25 MB, while Outlook limits vary by account or service.

Option 1: make the video smaller, then send it anywhere

This is the best choice for chats, email and quick sharing. A phone records at a very high bitrate, so most of the file size can go away with little visible difference.

1. Open the video compressor and add your video (MP4, MOV, M4V, WEBM, MKV or AVI, up to 100 MB).
2. In Quality, choose Smallest file (up to 720p) for WhatsApp or email. Choose Balanced (up to 1080p) if you have more room and want a sharper picture.
3. Click Compress video, wait for the bar to finish and download the MP4.
4. Check the new size in your file manager. If it is under the limit of the app you are using, send it as usual.

The result is a standard MP4 (H.264 video, AAC audio) that plays on iPhone, Android, Windows, Mac and smart TVs. If the video is still too big, trim it in your phone's gallery first: length is the one thing a compressor cannot change. Our guide to reducing video file size explains what each quality level does.

Option 2: use a document or link for larger files

On WhatsApp: send it as a document

When you send a video from the gallery, WhatsApp may compress or resize it. WhatsApp allows documents up to 2 GB.

1. Open the chat and tap the attach icon (the clip or the +).
2. Tap Document and choose the video file.
3. On iPhone, the video must be in the Files app first: in Photos, tap Share, then Save to Files.

The person receives a file instead of a preview and has to tap it to download it, so warn them if they have little data or space left. A 1 GB video costs 1 GB of their mobile data.

From iPhone: Mail Drop or AirDrop

In the Mail app, attach the video and send. If it is too big for a normal email, Mail offers to use Mail Drop, which uploads it to iCloud and sends a download link that lasts 30 days. If the other person has an Apple device and is next to you, AirDrop is the fastest route of all.

Anything else: a cloud link

Upload the video to Google Drive, OneDrive or iCloud Drive and share the link. Before sending, open the sharing settings and make sure anyone with the link can view it, otherwise the person will see an "access denied" page.

iPhone to Android or Windows: check the format

iPhones usually record in the HEVC format inside a MOV file. Some Android phones, Windows PCs and TVs refuse to play it, even when it arrives in one piece. If you are sending to someone outside the Apple world, convert it first with MOV to MP4, or simply run it through the compressor, which also produces a compatible MP4. Videos from screen recorders or older cameras (WEBM, MKV, AVI) can be turned into MP4 with the MP4 converter.

Tips that save time

• Don't zip a video to make it smaller. It is already compressed, so a ZIP saves almost nothing.
• Don't compress the same video twice. Each round loses a little more detail. Always start again from the original.
• For email, aim lower than the limit. Attachments grow by about a third in transit; our guide on attachments that are too large explains why.
• Record smaller next time. If you mostly share videos, 1080p at 30 fps is plenty. It takes up a fraction of the space of 4K at 60 fps.

Common questions

Why does my video look blurry after sending it on WhatsApp?

WhatsApp usually compresses media shared normally, and its default video size and resolution depend on your connection: up to 100 MB at 720p on faster connections, or 64 MB at 480p on slower ones. Sending it as a document uses the separate 2 GB document limit; compressing it yourself first lets you control the result.

My video is over 100 MB. Can I still compress it here?

Not in one piece: the compressor accepts files up to 100 MB. Trim it into shorter parts on your phone and compress each part, or send the original as a WhatsApp document or a cloud link.

Will the person receiving it need a special app?

No. An MP4 with H.264 video opens in the default player of practically every phone, computer and TV.

Is it better to send many short videos or one long one?

For chats, short clips are easier: each one fits the limit on its own and the person can watch them as they arrive. For something to keep, one file through a cloud link is tidier.
