How to Send Large Files from Your Phone via Email

Your phone is full of files you need to share — project documents, high-resolution photos, presentation decks, scanned contracts, even videos from a site visit. You open your email app, attach the file, and... it's rejected. Too large.

On mobile, this problem is even more frustrating than on desktop. Phone email apps have tighter attachment limits, fewer workarounds, and often default to cloud sharing without asking. Whether you're using the Gmail app, Outlook mobile, or Apple Mail, the result is the same: files over 20–25MB simply won't attach.

SendSplit solves this. It lets you send files up to 200MB from your phone as real email attachments — no app installation required, works entirely in your mobile browser.

Why sending large files from your phone is difficult

Mobile email apps impose strict limits:

  • Gmail app (Android/iOS): 25MB attachment limit — files over this are automatically uploaded to Google Drive as a link
  • Outlook mobile: 20MB limit — large files get redirected to OneDrive
  • Apple Mail: 20MB default — offers "Mail Drop" which sends an iCloud link instead of a real attachment
  • Samsung Email / other apps: Varies, typically 20–25MB

The common fallback — cloud links — creates problems for your recipients:

  • They may not have the right cloud account to access the file
  • Corporate firewalls often block Google Drive, OneDrive, or iCloud links
  • Links expire after a set period
  • Recipients on their own phones may struggle with cloud download pages

How to send large files from your phone with SendSplit

SendSplit works entirely in your mobile browser — Safari, Chrome, Firefox, or any other. No app download needed.

  1. Open sendsplit.com/upload-to-send on your phone
  2. Tap "Choose File" or "Browse" to select a file from your phone's storage, camera roll, or file manager (up to 200MB)
  3. Select a split size: 10MB, 20MB, or 25MB
  4. Enter the recipient's email address
  5. Tap send

SendSplit compresses and splits your file into smaller parts, then delivers each part as a real email attachment. Your recipient opens the emails, downloads the attachments, and extracts to get the original file.

Sending a large file from your phone with SendSplit

What types of files can you send from your phone?

SendSplit handles any file type your phone can produce or store:

  • Photos and videos — High-resolution images (HEIC, JPEG, PNG) and videos (MP4, MOV) from your camera roll
  • Documents — PDF contracts, Word files, Excel spreadsheets, PowerPoint presentations
  • Scanned documents — Files from scanning apps like Adobe Scan, CamScanner, or your phone's built-in scanner
  • Audio files — Voice memos, podcast recordings, music files
  • Archives — ZIP or RAR files containing multiple items
  • Design files — CAD drawings, Photoshop files, or other creative assets saved to your phone

Tips for sending from mobile

  • Use Wi-Fi when possible — Uploading files over 50MB on cellular data can be slow and may use significant data allowance
  • Choose the right split size — If you're unsure about the recipient's email provider, 10MB or 20MB is safest
  • Check your file size first — On iPhone, use the Files app to check size. On Android, use the file manager's "Details" option
  • Bookmark SendSplit — Add sendsplit.com to your home screen for quick access (works like an app without installation)

Why not just use a cloud app?

You could upload to Google Drive, Dropbox, or iCloud and share a link. But:

  • It requires the recipient to have the matching cloud service or deal with web downloads
  • Shared links can expire, get blocked by firewalls, or require authentication
  • You lose control once a link is shared — the file sits on cloud servers indefinitely
  • SendSplit delivers real attachments that stay permanently in the recipient's inbox and can be opened offline

With SendSplit, your files are processed temporarily and automatically deleted after delivery. Optional password protection adds extra security for sensitive files.

Who needs this?

  • Field workers and contractors sending site photos, inspection reports, or documentation from job sites
  • Sales professionals emailing proposals and presentations while traveling
  • Healthcare workers sharing medical images or records from mobile devices
  • Students and educators submitting or distributing large assignments
  • Anyone who needs to send a file that's too large for their phone's email app

Send files from your phone without the hassle. Try SendSplit — upload from your mobile browser and deliver up to 200MB as real email attachments.
