Email services cap attachment sizes. Here's how to shrink photos so they send quickly and don't bounce — free and private, in your browser.
Why emails bounce on large photos
Modern phone photos can be several megabytes each. Attach a handful and you can easily exceed the 20–25MB limit most email providers enforce — or just make the message slow to send and download. Compressing first solves both.
Shrink your images
Set a comfortable target — a few hundred KB per photo is usually plenty for email — and compress each image before attaching.

Best practices for emailing photos
- Resize huge photos to around 1600px on the long edge before compressing.
- Aim for 200–500KB per photo for a good balance of quality and speed.
- For many photos, compress each and consider zipping them together.
- Keep the originals — send compressed copies, not your only version.
Compression runs on your device, so your photos are never uploaded to a third-party server.
