Compress an Image for Email — Free & Private

Email has two size problems. The first is the hard cap: Gmail stops attachments at 25 MB, Outlook.com at 20 MB, and many company mail servers bounce anything above 10 MB, often without telling the sender why. The second is quieter: a message carrying 30 MB of photos sits in the recipient's mailbox for years, chokes a phone on a weak connection and gets held back by some corporate filters. This page is preset to 250 KB per image, which keeps a dozen photos under 3 MB in total and well clear of every common limit.

At 250 KB a photo from a phone looks essentially unchanged when viewed in a mail client or opened on a laptop. The dimensions are usually left alone and only the quality is trimmed; very large originals may come back somewhat smaller in pixels. What the recipient cannot do is print the image at poster size or crop in heavily, so if you are sending photos to a designer, a printer or anyone who will edit them, share the originals through a file link instead and use this page for everything else. Compress each photo here, then attach the results; the work happens on your own computer, so there is no waiting for an upload before you can send.
