How to Compress a Photo for Email (Free)

Attachment limits are the silent killer of email. Here's how to shrink photos so they actually send — free, and still sharp enough to look good.

Most email providers cap attachments around 20–25 MB, and a handful of high-res phone photos blow past that fast. Instead of fighting with cloud links for a couple of pictures, it's usually quicker to compress them so they slip under the limit and just send.

How small do email photos need to be?

For something the recipient will view on screen — not print — a few hundred KB per photo looks great. That means you can comfortably attach a dozen compressed photos in a single email. Only bump the quality up if the person genuinely needs print-resolution files.

Compress your photos for email — free

Open the compressor, add a photo, drag the quality slider until the size read-out shows a few hundred KB, and download. Repeat for each photo, then attach the smaller versions. It's free, runs in your browser, and adds no watermark.

A quick tip for lots of photos

If you're sending many images, resize them to around 1600px on the long edge before compressing — screens don't need more than that, and the files get much smaller. You'll fit far more into one email without anyone noticing a quality difference.
