How to Compress a Video to Send for Email

Sending videos through email can be a hassle due to strict attachment size limitations. For example, platforms like Gmail and Outlook typically cap attachment sizes at 25 MB or less, making it difficult to share even moderately sized video files. What’s particularly frustrating is when your video is just a few megabytes over the limit, leaving you unable to send it.

Fortunately, compression offers a straightforward and effective solution. By reducing the file size, you can keep your video attachments within the allowable limits while ensuring the process remains secure and under your control. This blog outlines a few practical methods to compress your videos for email, so you can share your files easily without compromising quality or security.

Why Don’t Email Servers Compress Your Video for You?

At first glance, it might seem logical for email providers to automatically compress large video files into a size that meets their attachment limits. However, there are several challenges that make this impractical:

Image Quality and File Size Trade-Off

Compression often leads to a reduction in image quality, which is a subjective matter. What looks acceptable to one person might be unacceptable to another. For email providers, it’s nearly impossible to set a universal standard for acceptable quality that works for all users. Read more about how large should a video be.

High Computational Costs

Video compression is a resource-intensive process that requires significant computational power. For email servers, handling this for millions of users would be both costly and time-consuming. Additionally, uploading large files to these servers consumes considerable network bandwidth, which further adds to operational costs for the provider.

These limitations are why email providers enforce strict size limits instead of attempting to compress videos on your behalf. Fortunately, there are user-friendly tools and methods available to help you compress videos before sending them—ensuring your files stay within attachment limits while maintaining control over quality.

Online Video Compression Services for Emails

When it comes to compressing videos quickly and efficiently, online tools are an excellent choice. They are accessible, easy to use, and require no additional software installation. Here are two reliable options:

Freeconvert.com is another versatile website that supports video compression with customizable settings. It allows users to adjust parameters like resolution, bitrate, and file size limits, giving more control over the final output.

Using Temporary Storage for Large Videos for Emails

If your video file is too large to send directly via email, temporary storage services can be a practical workaround. These platforms allow you to upload your video to a temporary space and share a download link with the recipient. Here are three popular options:

Google Drive: Google Drive is a widely used cloud storage service that integrates seamlessly with Gmail. You can upload your video to Drive and share a link directly within your email. While convenient, managing access permissions (e.g., ensuring the recipient has the right to view or download the file) can be an extra step. Additionally, if the recipient is unfamiliar with Google Drive, it may create unnecessary friction.

Dropbox: Dropbox is another trusted option for sharing large files. It offers features like password protection and link expiration for added security, making it suitable for professional use. However, Dropbox’s free plan has storage limitations, and the presence of ads or branding on shared links can come across as less polished in certain professional settings.

WeTransfer: WeTransfer is a straightforward platform that allows you to send large files without requiring an account. Simply upload your video, enter the recipient’s email address, and WeTransfer will handle the rest. However, the free version includes ads, and recipients may find the branding or promotional content unprofessional. Additionally, files are only available for a limited time, which may require careful coordination.

While these services can be convenient, they do come with downsides, such as added management for accessibility settings and potential distractions from ads. For situations where professionalism is key, compressing your video to fit email attachment limits may be a better option.

Find the Right Solution for Your Situation

Sending large video files through email doesn’t have to be a frustrating experience. By understanding the challenges of size limitations and the options available, you can choose the right solution for your needs. Whether you use a precise compression tool like Redpandacompress.com, opt for versatile platforms like Freeconvert.com, or temporarily store your video on services like Google Drive, Dropbox, or WeTransfer, there’s a method to ensure your files are sent efficiently and professionally. With these tips, you can keep your video sharing simple and stress-free.

iPhoneで動画を圧縮する方法

iPhoneで撮影された動画は、特に4Kなどの高解像度の場合、短いクリップでも数百メガバイト以上になることが多く、ストレージをすぐに圧迫し、共有が難しくなります。さらに、WhatsApp、Discord、メールなどの多くのソーシャルプラットフォームでは、数メガバイトに制限されたファイルサイズの上限が設けられているため、大きな動画は圧縮が必要です。

この記事では、iPhoneで動画を迅速に圧縮する3つの方法をご紹介します。

 iPhone内蔵の圧縮ツール


iPhoneには、動画圧縮専用の内蔵ツールはありません。唯一可能なのは、「写真」アプリを使用して動画を短くトリミングすることですが、これはファイルサイズを削減するものの、動画全体を保持したい場合には実用的ではありません。

サードパーティ製アプリ

App Storeから動画圧縮機能を提供するサードパーティ製アプリをインストールできます。以下は人気のあるオプションです:

これらのアプリは一般的に良好な圧縮結果を提供しますが、以下の点に注意が必要です:

  • コスト: 多くのアプリは無料トライアルや有料版であり、最終的には支払いが必要です。中には、特定の機能をアンロックするために5つ星のレビューを要求するものもあり、プロフェッショナルとは言えません。
  • 利便性とセキュリティ: アプリのインストールは手間であり、多くは小規模な企業や個人によって開発されているため、データセキュリティに関する懸念が生じる可能性があります。

オンライン動画圧縮ツール

ブラウザを通じてオンラインで動画を圧縮する方法は、追加のソフトウェアをインストールせずに動画サイズを削減する便利な選択肢です。これらのツールは2つのカテゴリに分類されます:

アップロード、圧縮、ダウンロード型:

この方法では、動画をサーバーにアップロードし、サーバー側で圧縮を行い、圧縮後のファイルをダウンロードします。効果的ですが、以下の欠点があります:

  • 時間がかかる: 大きな動画のアップロードとダウンロードには時間がかかります。
  • モバイルデバイスでのコスト: データ転送が多くのモバイルデータを消費する可能性があります。
  • プライバシーの懸念: プライベートな動画を外部サーバーに共有することは、セキュリティリスクを伴う可能性があります。

信頼できるオプションとして、Freeconvert.comがあります。無料で最大1GBの動画をサポートし、高速で高品質な圧縮を提供します。
videosmaller.comも同様のパターンに従っており、最大500MBの動画圧縮に対応しています。

ブラウザ内圧縮型:

この方法では、動画の圧縮が直接ブラウザ内で行われ、サーバーへのアップロードは不要です。以下の利点があります:

  • 大きなファイルに対して高速: アップロードやダウンロードが不要なため、時間を節約できます。
  • より安全: 動画はデバイス上に留まり、プライバシーの懸念が軽減されます。

ブラウザベースのツールは、ブラウザの制約により処理が遅くなることがありますが、最大2GBまでのファイルサイズに対応しています。おすすめのツールとして、Redpandacompress.comがあります。安全で効率的な圧縮を提供し、最大2GBの動画に対応しています。また、動画の最適なサイズを計算する自動化ツールも提供しています。

最適な方法の選択

最適な方法の選択は、以下の優先事項によります:

  • 速度と手軽さ: サードパーティ製アプリやサーバーベースのオンラインツールが適しています。
  • プライバシーと大きなファイルの処理: ブラウザベースのオプションであるRedpandacompress.comが優れた選択肢です。

各方法には利点と欠点があり、ニーズに合わせて最適なものを選択してください。

How to Compress a Video on iPhone

Videos shot on an iPhone, especially in high resolutions like 4K, are often very large, with even short clips taking up hundreds of megabytes or more. This can quickly fill up storage space and make sharing difficult. In addition, most social platforms, such as WhatsApp, Discord, and email, impose strict file size limits on uploads, often capping videos at a few megabytes. This means large videos need to be compressed before they can be shared.

In this article, we’ll explain how to quickly compress videos on your iPhone using three methods: the built-in iPhone tools, iOS apps, and online video compressors.

Built-in iPhone Compression Tool

As far as I know, iPhones do not have a built-in tool specifically designed for video compression. The only option available is to trim the video into shorter clips using the Photos app. While this reduces the file size, it’s not a practical solution for most cases where the entire video needs to be preserved.

Third-Party Apps

You can install third-party apps from the App Store that offer video compression functionality. Some popular options include:

These apps generally deliver good compression results, but there are some downsides:

  • Cost: Most of these apps are either free trials or paid, meaning you’ll eventually need to pay. Some even require a 5-star review to unlock certain features, which feels unprofessional.
  • Convenience and Security: Installing an app can be inconvenient, and many are developed by small companies or individuals, which may raise concerns about data security.

Online Video Compressor

Online video compression through a browser is a popular and convenient choice for reducing video sizes without installing additional software. These tools fall into two categories:

1. Upload, Compress, and Download

With this method, you upload your video to a server, the server compresses it, and you download the compressed file. While effective, it has some drawbacks:

  • Time-Consuming: Uploading and downloading large videos can take a long time, especially with slower internet connections.
  • Costly for Mobile Devices: Data transfer can consume a significant amount of mobile data.
  • Privacy Concerns: Sharing private videos to external servers may pose security risks.

A reliable option in this category is Freeconvert.com. It supports videos up to 1 GB for free and offers fast compression with good quality.

2. In-Browser Compression

This method performs the compression directly within your browser, without uploading the video to a server. It has several advantages:

Faster for Large Files: Avoids the need to upload or download, which saves time.

More Secure: Videos remain on your device, reducing privacy concerns.

In-browser compression can be slower due to the limitations of browser-based tools but supports larger file sizes, often up to 2 GB.

Redpandacompress.com: A great choice for this category, offering secure and efficient compression for videos up to 2 GB. It also provides an automated size calculation tool for you to know the right size for your video. Learn how large should a 5 minute HD video be.

Both types of online compressors have their pros and cons, and the best choice depends on your priorities—speed, security, or file size limits.

Find the Best Method for Your Needs

Choosing the right method depends on your priorities. If you value speed and ease, third-party apps or server-based online tools might be the way to go. For those concerned about privacy and handling larger files, browser-based options like Redpandacompress.com are excellent choices.
