Yes—when a photo is attached as a file, email normally transports the file data rather than sanitizing it. MIME specifies reversible transfer encodings, and a 2025 controlled study found identical hashes and complete tested EXIF retention for email attachments. Photo-app resize options can be an exception.
The strongest reading of the current sources
RFC 2045 defines transfer encodings such as Base64 so a receiver can restore the original encoded octet sequence. The independent study then observed matching hashes and retained EXIF for its email-attachment transfers, providing implementation-level support for the standards-based expectation.
Email transport and the app used to prepare the attachment are separate stages. A mail or photo app may offer Small, Medium, Large, compatibility conversion, or inline-image choices that alter the file before MIME transport begins.

RFC 2045: Multipurpose Internet Mail Extensions (MIME) Part One
The MIME standard defines reversible content-transfer encodings: valid encoded octets decode to the original encoded octet sequence rather than becoming a metadata-cleaning step.
Forensic Value of Exif Data: An Analytical Evaluation of Metadata Integrity across Image Transfer Methods
A controlled Android, iOS, and reference-image study compared hashes and EXIF fields after multiple transfer methods, separating compressed image modes from file or document modes.
What remains uncertain
- A sender can resize, convert, or recompress an image before it becomes an attachment, especially through a mobile photo share sheet.
- Security gateways and unusual mail systems can transform attachments; the MIME standard does not promise that every intermediary preserves every file unchanged.
- Inline previews are not necessarily the same object as the downloadable attachment.
What to do before you share
- 01
Assume a file attachment preserves EXIF and GPS unless you deliberately clean or convert it first.
- 02
Choose an explicit file attachment rather than a resized photo option when original fidelity is required.
- 03
For sensitive sharing, clean a copy first and inspect the downloaded attachment after delivery.
Quick clarifications
Does Gmail remove EXIF data from attachments?
This brief does not claim a Gmail-specific guarantee. Standard file attachments are designed to carry file data reversibly, but the safest privacy workflow is to remove sensitive metadata before attaching the file.
Does emailing a photo remove its GPS location?
Do not assume so. The reviewed study found GPS and other EXIF preserved in its email attachments, while a photo app’s resize or conversion option could produce a different result.
