How to Reduce Photo Size for Email and WhatsApp

Image Compressor · Guide

Phone photos have quietly grown into 3–12 MB files. Attach four of them to an email and you can blow past the limit; drop a few into a chat and they upload slowly and eat data. The fix is simple: shrink them before you send. Here's how to do it without them looking bad.

Why they're too big to send

Most email providers cap attachments at around 20–25 MB total. Chat apps like WhatsApp are more generous but re-compress your photo their own way — often making it look worse than if you'd prepared it yourself. In both cases, a little compression up front gives you smaller files and more control over quality.

For email

  1. Add your photos to the compressor.
  2. Keep quality around 75–80 — invisible loss, big savings.
  3. If you're attaching several, aim for roughly 1–2 MB each so the whole email stays comfortably under the limit.
  4. Download and attach the compressed versions.

For documents and scans where text must stay crisp, keep quality a little higher or use PNG.

For WhatsApp and social

If you want your photo to survive the app's own compression, send it close to the size the platform displays it at. Resizing the width to around 1080–1600px and compressing to a few hundred KB usually looks sharp and uploads instantly. Sending a raw 12 MB file just gives the app more to crush.

Sharing on a slow connection? A 300KB photo sends in a second where a 6 MB one stalls. Your recipients on limited data will thank you.
