RAW vs JPEG

What Is a RAW File?

A RAW file holds unprocessed data captured directly from your camera's image sensor. It is not a finished photograph — it is more like a digital negative. RAW files preserve everything the sensor recorded: full bit depth (typically 12–14 bits per channel), complete dynamic range, zero in-camera processing decisions. Nothing has been baked in. You make all the exposure, colour, and detail decisions yourself in editing software afterward.

Common RAW formats include CR2 and CR3 (Canon), NEF (Nikon), ARW (Sony), RAF (Fujifilm), ORF (Olympus), RW2 (Panasonic), PEF (Pentax), and DNG (Adobe's open standard). Every manufacturer names their format differently, but they all capture the same fundamental thing: raw, unprocessed sensor data.

What Is a JPEG?

JPEG is a finished image format. When your camera produces a JPEG, it applies a complete processing pipeline internally: demosaicing, white balance correction, colour grading, noise reduction, sharpening, and finally lossy compression. The result is a universally compatible image ready to share, print, or post immediately. The trade-off is permanence — some image data is discarded to keep file sizes small, and the decisions the camera made cannot be fully undone.

Most consumer cameras default to JPEG because the results need no additional software. Images come out looking good straight from the camera, and file sizes are manageable.

RAW vs JPEG: Key Differences

File size: RAW files are large — typically 20–50 MB each — because they retain all sensor data. JPEGs from the same camera are usually 3–10 MB after in-camera compression.

Editing headroom: RAW files can absorb heavy adjustments without quality loss because all the original data is intact. With JPEG, aggressive edits degrade quality quickly — there is less data to work with, and the compression artefacts already present get amplified.

Compatibility: Every browser, app, and device opens JPEGs natively. RAW files require dedicated software — Lightroom, Capture One, Darktable, or a browser-based converter like JustConvertRAW.

Colour depth: RAW captures 12–14 bits per colour channel, allowing fine tonal gradations. JPEG stores 8 bits per channel — sufficient for most uses, but less forgiving when you push the edit hard.

White balance: In a RAW file, white balance is metadata — it can be changed freely in editing without touching image quality. In a JPEG, white balance has been applied and compressed in; changing it costs quality.

When to Use Each

Choose RAW when maximum editing control matters: professional assignments, challenging lighting, studio work, portraits where skin tone accuracy is critical, or landscapes with high dynamic range. If you are not sure you will get it right in-camera, shoot RAW so you can fix it later.

Choose JPEG when speed and simplicity matter: casual photography, events where you need to deliver images quickly, or situations where storage is tight. Many photographers shoot RAW+JPEG simultaneously — the JPEG for quick turnaround, the RAW for archiving and detailed post-processing later.

Converting Between Them

Converting RAW to JPEG is straightforward — that is exactly what JustConvertRAW does. Head to the home page, drop any RAW file into JustConvertRAW, and download a high-quality JPEG in seconds, processed entirely in your browser with no upload required.

Converting JPEG to RAW is not possible. When your camera created the JPEG, it discarded the original sensor data permanently. No software can reconstruct what was never saved. If you have been looking for a JPEG-to-RAW converter, the explanation of why that does not exist — and what to do instead — is covered in the linked guide below.
