How to Reduce Photo Size for Email (Without Losing Quality)

Modern phone photos are often 3–10 MB each. Attach a few and you hit the 20–25 MB limit of Gmail, Outlook and most email services, and even when they fit, big attachments are slow to send and download.

The good news: a photo for viewing on screen needs a fraction of that size.

The quick way: compress for email

1. Open Compress Image for Email.
2. Drop in your photos, up to 30 at once.
3. Click Compress Image. Each photo comes out under 500 KB.
4. Download them as a ZIP and attach it, or attach the photos individually.

The compressor keeps the highest quality that fits, so photos still look sharp on phones and laptops.

Need a specific size?

Some forms and services have their own limits. Use a preset:

• Compress to 100 KB
• Compress to 200 KB
• Compress to 1 MB

Or open Compress Image and type any target size in KB.

Also shrink the dimensions

A 12-megapixel photo (about 4000 × 3000 pixels) is far bigger than any screen. Resizing to around 2000 pixels on the long side cuts the file size dramatically while looking identical on screen. Use Resize Image, then compress.

Remove hidden location data first

Photos from phones often contain the exact GPS location where they were taken. Before emailing photos to people you don't know well, remove the EXIF data.

When not to compress

If the recipient needs to print large photos or edit them professionally, send the originals through a cloud link (Google Drive, iCloud, OneDrive, Dropbox) instead of compressing them.
