Every mirrorless camera, DSLR, and even most smartphone camera apps now offer a “RAW” shooting mode alongside JPEG. It’s presented as the “professional” option, which makes a lot of casual photographers feel like they should be using it — right up until they see the file sizes and realize their memory card fills up ten times faster. Here’s what RAW format actually is, what it genuinely gets you, when it’s worth the tradeoff, and what to do with a RAW file once you’ve got one and just want to post it somewhere.
What RAW Actually Is
A RAW file is essentially the unprocessed data captured directly by a camera’s image sensor — the raw brightness and color values recorded at each pixel location, before the camera applies any of the processing decisions that turn that data into a finished-looking photo.
When a camera saves a JPEG, it’s making a series of permanent decisions on your behalf: white balance, contrast curve, sharpening, noise reduction, color saturation, and lossy compression — all baked in and largely undoable afterward. A RAW file skips all of that. It stores the sensor data either completely uncompressed or losslessly compressed (meaning no image information is discarded, unlike JPEG’s lossy approach), leaving every one of those processing decisions open for you to make later, in software, instead of the camera making them permanently at the moment of capture.
This is also why a RAW file isn’t really a single standardized format — it’s closer to a family of formats, each tied to a camera manufacturer’s own sensor: Canon’s .CR2/.CR3, Nikon’s .NEF, Sony’s .ARW, and the vendor-neutral .DNG (Adobe’s attempt at a universal RAW standard) are all “RAW,” but they’re not interchangeable file formats in the way JPEG or PNG are.
Why RAW Files Are So Big
| Format | Typical file size (24MP camera) | Why |
|---|---|---|
| JPEG (standard quality) | 5–12 MB | Lossy compression discards imperceptible detail; processing already baked in |
| RAW (compressed) | 25–45 MB | Losslessly compressed, but no data discarded — every sensor reading preserved |
| RAW (uncompressed) | 60–100+ MB | No compression at all applied |
The gap is large — often 5–10x — because RAW is deliberately keeping everything: full sensor bit depth (typically 12–14 bits per channel versus JPEG’s 8-bit), no discarded detail, no baked-in processing. A single day of RAW shooting on a modern camera can easily produce tens of gigabytes, which is the single most common reason people back away from shooting RAW after trying it once.
RAW vs JPEG: What You Actually Get
| Factor | RAW | JPEG |
|---|---|---|
| File size | Large (20–100MB+) | Small (2–15MB typical) |
| Processing | None applied — you decide everything afterward | Baked in by the camera at capture time |
| Editing latitude | Full — recover blown highlights, shift white balance, pull up shadows with minimal quality loss | Limited — aggressive edits reveal banding, artifacts, color shifts |
| Bit depth | 12–14 bits per channel (billions of color values) | 8 bits per channel (16.7 million color values) |
| Ready to share immediately | No — requires conversion/export first | Yes — usable straight off the camera |
| Software needed to view/edit | A RAW-capable editor (Lightroom, Capture One, or free tools like RawTherapee/darktable) | Opens natively everywhere |
The single biggest practical advantage of RAW is editing latitude — specifically, the ability to recover detail that looks lost. A photo where the sky is blown out white, or a subject’s face is too dark in shadow, often still has real recoverable data in a RAW file that simply isn’t there anymore in a JPEG, because the camera already discarded it during JPEG compression. Pull the exposure slider on a RAW file and detail reappears; do the same to a JPEG and you mostly get noise and banding.
When RAW Actually Matters
Shoot RAW when:
- You’re photographing in genuinely difficult or unpredictable lighting (harsh sun, mixed indoor lighting, sunset/golden hour) where you’ll want to correct exposure or white balance afterward
- You plan to seriously edit the photo — professional retouching, significant color grading, print production
- You’re shooting something you can’t reshoot (a wedding, an event, a one-time moment) and want maximum recovery options if you got the exposure slightly wrong
- Storage and processing time genuinely aren’t a constraint for you
JPEG is the better call when:
- You’re shooting casually — family photos, travel snapshots, social media content
- You want to share images quickly without an editing/export step in between
- Storage space or upload speed matters (a phone, a small memory card, a slow connection)
- Your camera’s built-in processing already produces a result you’re happy with
For the average person taking photos day to day, JPEG is genuinely not a compromise — it’s the correct, faster choice. RAW is a tool for a specific kind of control, not an automatic upgrade over JPEG the way “higher resolution” or “more megapixels” tend to be.
What to Do With RAW Files for Web Use
This is the part that trips people up: a RAW file can’t be used directly on a website, in an email, or on social media. No browser renders .CR2 or .NEF files, and most platforms won’t even accept them as an upload. RAW has to be converted to a standard image format — typically JPEG, PNG, or WebP — as an export step, whether that happens automatically in your camera app or manually in editing software.
The practical workflow:
- Edit the RAW file in whatever software supports it (Lightroom, Capture One, or free options like RawTherapee and darktable) — this is where you actually use the extra editing latitude RAW gives you.
- Export to JPEG, PNG, or WebP once editing is done — most RAW editors have a built-in export function, but if you’re starting from an already-exported file in the wrong format, AllMediaTools Image Converter handles converting between standard web formats afterward.
- Compress before publishing. A freshly exported JPEG from RAW editing software can still be unnecessarily large for the web — see why large image files slow down a website for why this matters, and run the export through AllMediaTools Image Compressor before uploading it anywhere.
Note that AllMediaTools’ tools work with standard raster formats (JPEG, PNG, WebP) — they don’t open camera RAW files directly, since RAW processing requires interpreting sensor-specific data, not just converting between already-decoded pixel formats. You’ll always need a RAW-capable editor for the first step; AllMediaTools picks up once you’ve exported to a standard format and want it web-ready.

Frequently Asked Questions
Is RAW actually better quality than JPEG?
RAW captures more data (higher bit depth, no lossy compression, no baked-in processing), which gives you more room to edit without visible quality loss. But a well-exposed JPEG straight out of camera can look just as good as a RAW file for casual viewing — the difference shows up specifically when you need to significantly edit or recover detail, not in a side-by-side glance.
Do I need special software to open RAW files?
Yes — standard photo viewers and web browsers can’t open camera RAW formats directly. You need a RAW-capable editor: Adobe Lightroom or Photoshop (paid), Capture One (paid), or free alternatives like RawTherapee and darktable.
Why are RAW files so much bigger than JPEG?
RAW preserves the full sensor data — typically 12–14 bits per color channel versus JPEG’s 8 bits — with no lossy compression discarding detail, and no processing decisions baked in yet. That’s roughly 5–10x more data retained per pixel compared to a standard JPEG.
Can I convert a RAW file straight to JPEG without editing it?
Yes — most cameras and RAW editors can export a RAW file to JPEG using default or automatic settings with no manual adjustment. You lose the point of shooting RAW in the first place if you never touch the extra editing latitude, but it’s a valid option if you shot RAW as a safety net and the default result already looks fine.
Should a beginner shoot RAW or JPEG?
JPEG, in most cases — it’s simpler, faster to work with, and doesn’t require learning RAW editing software just to get a usable photo. RAW becomes worth learning once you find yourself regularly wishing you could recover a blown-out sky or fix white balance after the fact, which is usually a sign you’re ready for the extra step.
