How to Convert HEIC to JPG for Email Attachments

Why Convert HEIC to JPG for Email?

Most email services — Gmail, Outlook, Yahoo, and others — do not support HEIC image attachments. When you try to attach a .HEIC photo from your iPhone to an email, the recipient on Windows or Android will likely see a "file format not supported" error or a generic file icon instead of your photo. Converting HEIC to JPG solves this: JPEG is the most universally supported image format for email. Every email client, operating system, and device can display JPG attachments inline. Additionally, JPEG files are typically smaller than HEIC at display resolution, making them faster to upload as email attachments.

How to Convert HEIC to JPG for Email in 3 Steps

Making your iPhone photos email-friendly takes just a few seconds:

• Open our converter in your browser (works on iPhone, Mac, or PC)
• Select the HEIC photo(s) you want to email — drag and drop or browse to choose
• Choose JPEG output format. For email, quality 80-85% is recommended: good visual quality with small file size for faster attachment uploads

The Right JPEG Quality Settings for Email

For email attachments, you don't need maximum quality — email services often compress images anyway. Our recommended settings:

• Quality 85% — excellent visual quality, ~60% smaller than quality 100. Ideal for most email attachments
• Quality 70% — good quality, ~75% smaller. Suitable when file size matters (e.g., multiple attachments)
• Quality 50% — acceptable quality, ~85% smaller. Use only if you need to squeeze under attachment size limits

Email Attachment Size Limits (2026)

Different email services have different attachment size limits. Here's a quick reference: Gmail allows up to 25 MB per email, Outlook (Hotmail) allows up to 20 MB, Yahoo Mail allows up to 25 MB, and iCloud Mail allows up to 20 MB. A typical iPhone HEIC photo (2-3 MB) converted to JPEG at 85% quality becomes roughly 1-2 MB — well within any service's limit, even when attaching multiple photos. If you need to send many photos, consider our batch converter with ZIP download: compress them into a single archive under the size limit.
