It is not the photo — your iPhone camera is fine
The first thing to understand is that your iPhone is taking excellent photos. The 48-megapixel cameras in recent iPhones capture more detail than most people will ever need. When your Android friend receives a blurry, pixelated image, the problem is not the camera — it is what happens to the photo between taking it and it arriving on the other side. There are three distinct causes, and each one needs a different fix.
Cause 1: SMS/MMS compression by carriers
This is by far the most common reason iPhone photos arrive blurry on Android. When you send a photo in a standard text message (the green bubble in iMessage), you are not sending it via iMessage — you are using MMS, a standard that predates smartphones by over a decade. Mobile carriers impose strict file size limits on MMS messages, typically 300KB to 1.2MB depending on the carrier and country.
Your iPhone photo is probably 4–12MB. The phone silently compresses it down to fit the MMS limit — often reducing it by 90% or more. A 10MB photo becomes 600KB, and the quality loss is brutal: fine details disappear, colours wash out, and text in images becomes unreadable. The recipient has no way to know they received a compressed version — it just looks blurry.
The fix for this cause is simple: stop using SMS/MMS for photos. Use a messaging app that sends photos over data rather than through the carrier's MMS system. WhatsApp, Telegram, and Signal all send photos at full quality over an internet connection. Regular email also works well for full-quality attachments.
Cause 2: The HEIC format Android cannot read properly
Apple switched its cameras to HEIC format by default several years ago. HEIC (High Efficiency Image Container) produces photos roughly half the size of equivalent-quality JPEGs, which is why Apple uses it — it saves storage space on your phone. The problem is that Android support for HEIC has historically been inconsistent.
When an Android phone receives a HEIC file it cannot display natively, it falls back to either showing a placeholder, rendering a very low-quality thumbnail, or requesting a conversion from the OS — any of which can produce a blurry result. Even when Android does display HEIC, some older phones and apps do it imperfectly.
The cleanest fix is to convert the HEIC file to JPG before sending. My HEIC converter does this entirely in your browser — no upload, no account, no quality loss from server-side processing. Drop in the file, get a JPG out, send that. It takes about five seconds.
Cause 3: Low Quality Image Mode in iMessage
Apple added a Low Quality Image Mode setting to iMessage that, when enabled, compresses all photos sent through iMessage to save data. If you have a limited data plan or turned this on at some point and forgot about it, every photo you send through iMessage arrives compressed.
Check: Settings → Messages → scroll to the bottom → Low Quality Image Mode. If it is toggled on, turn it off. This setting only affects iMessage (blue bubble) conversations — MMS is always compressed by the carrier regardless of this setting.
Cause 4: AirDrop compression quirks
AirDrop generally transfers files without compression, but there are edge cases. If you AirDrop a Live Photo to an Android user (via a bridge app or file transfer), the Live Photo component may not transfer correctly and the fallback still image can be lower quality. Converting to a standard JPG first avoids this entirely.
The permanent fix: change your camera format
If you are tired of managing this case by case, the permanent solution is to change what format your iPhone shoots in. Go to Settings → Camera → Formats → and select "Most Compatible" instead of "High Efficiency." Your iPhone will now shoot JPG by default. JPGs are slightly larger files, but they work everywhere — Windows, Android, every app, every website — with no conversion needed.
The downside is that JPGs take more storage space. On a 256GB iPhone this rarely matters, but if you are on a 64GB model and shoot a lot of video, it is worth considering. HEIC exists because it is genuinely better at compression — you just sometimes pay a compatibility price for it.
Quick summary: which fix to use
If photos look blurry when texted: switch to WhatsApp or email. If someone can't open your HEIC file: convert it to JPG using my free converter before sending. If iMessage photos are blurry: check the Low Quality Image Mode setting. If you want to never deal with this again: change camera format to Most Compatible in Settings.
