Key Takeaways

Email (Gmail, Outlook, Yahoo): 25 MB per message. Photos should be compressed to 500–800 KB each to batch multiple images in one email.
Cloud Storage (Google Drive, Dropbox): Very high limits (2–5 TB). Desktop apps handle large uploads more reliably than web browsers.
Professional Services: Slack (1 GB), SharePoint (250 GB). Slack is the bottleneck for team file sharing.
Why Compress? Even though upload limits are generous, compressed images load faster, save bandwidth, and are easier to share via email or messaging.

How to Prepare Images for Upload

Check the platform's limit (use this guide).
Compress to 50–80% quality using Compress Image. Quality 75% usually looks identical on screen but cuts file size 3–5×.
Choose the right format: JPEG for photos, PNG for graphics with transparency, WebP for highest compression.
Test on the destination device before relying on a compressed image (phone, email client, web browser).
For batch uploads, use Pro mode to compress 50+ images at once.

When to Use This Guide

You're uploading to an unfamiliar platform and need to know the file size limit.
Your image was rejected as "too large" and you need to compress it.
You're batch-uploading (e.g., 50+ photos to Google Photos) and want to optimize file sizes first.
You're integrating a web service and need to document upload limits for users.
