When you shoot in RAW, you capture far more image data than a JPG can hold, but that comes with a tradeoff: RAW files are large, need editing software to view properly, and aren’t accepted everywhere. That’s why photographers export JPG copies for sharing. It keeps your original editable file safe while giving you a small, universal format for email, social media, and upload forms.

What RAW Files Give You (and Why You Export JPG)

Camera RAW files (like CR2, NEF, ARW, and DNG) store 12 or 14 bits of data per channel, compared to JPG’s 8 bits. That extra bit depth gives you real headroom to recover highlight details, adjust white balance, and pull back shadows without banding. But that power comes at a cost: RAW files are large, and most photo viewers and email systems can’t display them directly. You need dedicated editing software to open them.

So when you finish editing a RAW file, you export a JPG copy for everyday sharing. JPG uses lossy compression to shrink file size, and it’s accepted almost everywhere, from email attachments to online forms. The key is to keep the original RAW file untouched and export a separate JPG for sharing. That way, you can always go back to re-edit the RAW later without losing quality.

How to Balance Quality and File Size

When you export a JPG, you choose a quality level. A common starting point is quality around 80 for web photos. That gives you a good mix of visual quality and small file size. But the right setting depends on what you’re sharing.

  • Email: A mid-range quality setting usually keeps files under a few megabytes, which is fine for most email limits.
  • Social media: Platforms often recompress images anyway, so a high-quality JPG is usually fine.
  • Print: If you’re sending to a print lab, use the highest quality setting and don’t resize down too aggressively.

Resizing to the size an image is displayed at usually saves more space than lowering quality. A very large photo downscaled to a smaller size will shrink dramatically, often more than dropping quality. So think about where the photo will be seen.

What About AI Upscaling?

Sometimes you have a small JPG and wish it were bigger. Upscaling software enlarges an image by predicting new pixels, but it cannot recover detail the camera never captured. That’s a hard limit: if the detail isn’t in the original file, no algorithm can invent it truthfully.

Modern AI Upscalers Are Cleaner, Not Magic

That said, modern AI upscalers produce cleaner results than simple resizing. They add plausible texture and sharpen edges, which can make an enlarged image look acceptable for screen use. But don’t expect them to turn a blurry 1-megapixel crop into a tack-sharp 20-megapixel print. They work best when you’re upscaling a reasonably detailed image by 2x or 3x.

For sharing, you’re usually better off exporting a properly sized JPG from your RAW file in the first place. That way, you keep all the original detail and only lose what the compression removes.

Why You Shouldn’t Edit and Re-save JPGs Repeatedly

JPG uses lossy compression, which means every time you save, it throws away some detail. If you edit a JPG, save it, open it again, edit, and save again, you lose a little more quality each time. This is often called generation loss. Over many generations, you’ll start to see artifacts, banding, and softness.

The fix is simple: always keep your original RAW file as the master. When you need a JPG, export a fresh copy from the RAW. If you must edit a JPG, do all your edits in one session and save once at the end. But the best practice is to treat JPGs as final output, not as working files.

PNG Isn’t the Best Choice for Photos

PNG is a lossless format that supports transparency, which makes it great for graphics, logos, and screenshots. But for photos, PNG files are much larger than JPGs. A typical photo saved as PNG can be two to five times bigger than the same photo as a JPG at quality 80. That extra size rarely buys you anything for photos, because the eye can’t easily see the difference between a high-quality JPG and a lossless PNG in normal viewing.

So if you’re sharing a photo online or via email, stick with JPG. Reserve PNG for images with text, transparency, or when you need an exact pixel-perfect copy.

Exporting JPG Copies: a Simple Workflow

Here’s a practical way to handle sharing without cluttering your workflow:

  1. Edit your RAW file in your chosen software.
  2. Export a full-size, high-quality JPG and keep it in an “Exports” folder if you might need it later.
  3. If you’re sharing online, create a second JPG resized to the display size at a moderate quality.
  4. Name files clearly, like “event_photo_01_web.jpg”.
  5. Never overwrite the original RAW or the high-quality JPG.

When you need to convert files quickly, a free JPG converter like jpg.now can handle the job. It converts RAW, HEIC, PNG, WebP, and PDF to JPG, and also compresses JPG files, all without sign-up. That’s handy when you receive a RAW from a friend or need to shrink a JPG for email.
