Most email providers limit attachments to 10–25MB total. Compress your photos to under 500KB each so they send quickly and don't clog up inboxes.

Why large email attachments bounce
Email providers like Gmail, Outlook, and Yahoo enforce strict attachment limits, typically capping total email size at 20MB to 25MB. If you try to send a handful of original photos from your phone, you will quickly hit this limit and your email will fail to send or bounce back.
Even if an email barely sneaks under the limit, sending massive attachments is inconsiderate to the recipient. It clogs up their inbox storage and can take a long time to download on slower mobile connections. Compressing images to under 500KB solves this problem entirely.
By reducing the file size, you can easily attach 20 or 30 photos to a single email without relying on clunky third-party cloud storage links. Our tool automatically resizes and optimizes your images directly in your browser, ensuring they remain clear enough for viewing while keeping your emails lightweight.
