How do I send an original photo without losing its quality?

Prefer a route that sends the original file or clearly identifies an original-data option. A photo displayed in a chat or email preview is not enough to tell you how that app handled the file, so don’t assume that a normal message preserves the original. Check the specific app’s sharing choices before sending, especially if the recipient needs to edit, print, or keep the file. For iPhone Photos, Apple describes an All Photos Data option that shares the original file with edit history and metadata; Apple says this option is available with AirDrop and iCloud Links. That is a product-specific feature, not a guarantee for other apps. [S1]

Either can work as a delivery method, but the route alone does not establish that the recipient gets an original-quality file. For iCloud Mail on iCloud.com, you can attach files from iCloud Drive, iCloud Photos, or your device. If an attachment is too large, Mail may offer Mail Drop, which uploads it to iCloud; recipients can download it for up to 30 days. Apple also notes that the recipient’s email-service size limit may still cause a message to be returned. [S2] Before relying on a link, consider whether the recipient can open it and whether its access settings suit your situation. Google Photos warns that anyone with a shared link can view the shared album, so treat link access as part of your choice. Its instructions describe sharing methods but do not establish that each one preserves original quality. [S3]

In iPhone Photos, open the sharing options and look for All Photos Data if you need the original file with edit history and metadata. Apple documents that option for AirDrop and iCloud Links; its guide says iCloud Links can be downloaded for 30 days. [S1] If you choose another app, look for a setting or send mode that explicitly describes original quality, full resolution, or sending as a file. App menus and behavior differ, and the sources here do not establish how other messaging apps compress photos. If the option is unclear, send a test photo to a device or recipient you can check first; don’t treat that test as proof about every file or future app update.

Use a note that tells the recipient what you intended to send and asks them to check the result. For example:

“Please download this photo using the link/attachment rather than saving a preview. I intended to send the original file. Could you confirm you can open it and that it suits your needs? If not, tell me which file-sharing method works for you.”

Replace “link/attachment” with the route you used. The note is a practical check, not a guarantee that the app preserved quality. If you need the photo’s edit history or metadata, name that requirement explicitly and use a route that documents support for it. The available product guidance does not establish the behavior of every recipient device, email service, or messaging app.
