How to send photos and videos without compression

The short answer: in almost every messaging app, the way to send a photo or video at full original quality is to send it as a file or document, not through the photo picker. WhatsApp, Telegram and Signal all leave documents untouched, and Messenger accepts files up to 100 MB. The "HD" switches that WhatsApp, Messenger, Instagram and Signal now offer give you a sharper copy, but it is still a recompressed copy. On iPhone, Messages keeps quality well between Apple devices as long as low-quality options are off, and an iCloud link is the cleanest way to share originals with anyone else.

Why the apps compress in the first place

A photo from a current phone camera is often 3 to 12 MB, and a minute of 4K video can run to several hundred megabytes. Messaging services handle billions of images a day, many of them on slow or metered mobile connections, so they resize and re-encode media by default. Standard-quality WhatsApp, for example, reduces a 12-megapixel iPhone photo to 960 × 1280 pixels. That is fine on a phone screen and useless for printing, editing or archiving.

Compression also strips or rewrites some metadata and can change formats: HEIC photos often arrive as JPEG, and videos are re-encoded at a lower bitrate. When you send something as a file, the app treats it like any other attachment, such as a PDF, and passes the bytes through as they are.

WhatsApp

Middle ground: HD

1. Open the chat and tap the attach or plus button, then pick the photo or video.
2. In the editor, tap the HD icon at the top and choose HD quality.
3. Send.

To make HD the default, go to Settings > Storage and data > Media upload quality and select HD. HD photos keep close to the original resolution with lighter compression; HD video is sent at 720p rather than 480p. Good enough for viewing, not a true original.

True original: send as a document

1. In the chat, tap the attach or plus button and choose Document.
2. Browse to the photo or video. On iPhone, save it to the Files app first if it does not appear; on Android, look in the DCIM or Pictures folder.
3. Send. The recipient sees a file with a name and size instead of an inline preview.

WhatsApp allows files up to 2 GB, according to its own announcement when it raised the limit from 100 MB.

iMessage (the Messages app on iPhone)

Between Apple devices on iMessage, photos usually arrive at good quality unless a data-saving option is on. Check Settings > Apps > Messages (on older iOS versions, Settings > Messages) and make sure Low Quality Image Mode is off. On recent iOS releases the related switch is labelled along the lines of "Send Low Quality Photo Previews": it sends a small preview first, and if Low Data Mode is also on, only the preview may be delivered. Turning off Low Data Mode for your Wi-Fi or cellular connection avoids that.

Large videos are still reduced in Messages, and anything sent to an Android phone goes over RCS or MMS, where quality drops further. For full originals from an iPhone:

• To another Apple device nearby: AirDrop. In the share sheet, tap Options and turn on All Photos Data if you also want the edit history and metadata.
• To anyone, anywhere: in Photos, select the items, tap Share, then Copy iCloud Link and paste it into any chat. The recipient downloads full-resolution files from a web page. The link expires after 30 days, and you need iCloud Photos turned on.
• To Android in person: see our guide on sending files from iPhone to Android.

Telegram

1. Open the chat and tap the paperclip.
2. Switch to the File tab (not Gallery).
3. Choose Gallery or Photo or Video inside the File tab, select the items, and send.

Files sent this way are not compressed. Telegram allows up to 2 GB per file, or 4 GB with a Premium subscription. Sending through the normal gallery picker compresses photos even when they look fine in the preview.

Signal

Signal compresses by default. Two settings help:

• Per message: after selecting a photo, tap the quality icon in the lower-left of the editor and choose High.
• Always: Settings > Data and storage > Sent media quality > High.

High sends photos at roughly 4K resolution, which is a big improvement on Standard but still recompressed. For an exact original, tap the plus button, choose File rather than Gallery, and pick the photo or video. Signal's attachment size limit is far lower than WhatsApp's or Telegram's (reported as around 100 MB), so long 4K videos may not fit.

Facebook Messenger

1. Pick a photo from the chat composer.
2. Turn on the HD toggle and send. HD photos are labelled "HD" in the chat.

For originals, tap the plus button and send the photo or video as a file. Meta says Messenger accepts files up to 100 MB in chats. Its HD option covers photos only; videos sent the normal way are still compressed.

Instagram and Facebook posts

Instagram added an HD icon to the photo picker in direct messages in early 2025; tap it before sending for a higher-resolution copy. There is no option to send an untouched original file in Instagram DMs. Posts, Stories and Reels on Instagram and Facebook are always re-encoded for streaming, so treat them as a way to publish, not a way to deliver a file someone will edit or print.

What arrives at the other end

How to check that the original actually arrived

It is easy to assume a photo came through intact because it looks sharp on a phone screen. A quick check on the receiving side settles it:

1. Compare file sizes. Ask the sender for the size shown on their device. If a 6 MB photo arrived as 400 KB, it was compressed.
2. Check the resolution. On iPhone, open the photo in Photos and swipe up (or tap the info button) to see the dimensions. On Android, Google Photos shows details when you swipe up. A 12-megapixel original is around 4000 × 3000 pixels; a compressed chat copy is often 1600 pixels or less on the long side.
3. Check the format. If an iPhone sent HEIC and you received JPEG, it was converted along the way. That is not always bad, but it is not the original.
4. For video, check bitrate and resolution. A desktop player such as VLC shows codec information. A 4K clip that arrives as 720p has been re-encoded.

Another tell: a file that saves straight into the camera roll was usually sent as media, and one that lands in a Downloads or Documents folder was usually sent as a file.

When a chat app is the wrong tool

Sending as a file solves quality, but chat apps still have per-file caps, and every file is uploaded to the service and downloaded again. For a whole shoot, a long 4K clip or anything over a couple of gigabytes, other routes are faster and less fiddly:

• Shared cloud folders or albums (iCloud links, Google Drive, Dropbox) when the recipient will download later. Google Photos sharing keeps originals only if your library is backed up in Original quality rather than Storage saver.
• Nearby transfers like AirDrop or Quick Share when you are in the same room on compatible devices.
• A direct browser transfer when the recipient is online now. With TransferFiles.net you pick the original files in your phone's browser and the recipient receives them byte-for-byte, with no recompression and no upload to a storage server. Both screens need to stay on until it finishes, and on phones very large multi-gigabyte files can fail because mobile browsers assemble the download in memory, so split big batches into smaller sends. Our guide to sending large video files goes deeper on video specifically.

Sending originals over mobile data adds up quickly; see how much data large transfers use before you send a 4K video on a capped plan.
