RAW vs JPEG: Which Should You Shoot to Save Storage?

If your only goal is saving storage, shoot JPEG (or HEIC on iPhone) and reserve RAW for the handful of photos you actually plan to edit — a single RAW or ProRAW file is often 20-50MB or more, while the same shot as a JPEG is roughly 3-6MB and as HEIC closer to 2-3MB. On iPhone you control this under Settings > Camera > Formats, and on most Android phones inside the Camera app > Settings. This guide is for anyone whose photo library is ballooning and who wants to know whether RAW is worth the space it costs.

TL;DR

  • RAW stores unprocessed sensor data, so files are huge: typically 20-50MB+ each.
  • JPEG and HEIC are compressed: usually 2-6MB for the same 12MP shot.
  • For pure storage savings, shoot HEIC (iPhone) or JPEG/HEIF (Android), not RAW.
  • Shoot RAW only for photos you'll genuinely edit; it gives editing headroom JPEG can't.
  • Switching format only affects new photos — your existing RAW files stay large until you clear them.

What's the real difference between RAW and JPEG?

The difference comes down to how much the camera throws away. A JPEG is a finished photo: the phone processes the sensor data, applies color and sharpening, then compresses it into a small, ready-to-share file. A RAW file keeps the unprocessed sensor readout instead, so nothing is baked in and nothing is discarded — which is exactly why it's so large.

That extra data buys you editing flexibility. With RAW you can recover blown-out skies, lift deep shadows, and change white balance after the fact with far less quality loss. With a JPEG, those decisions are already locked in, and pushing them hard introduces banding and artifacts. On Apple devices the modern middle ground is HEIC (compressed like JPEG but roughly half the size) and ProRAW (RAW with some Apple processing layered on).

For storage, the takeaway is blunt: RAW is the most expensive format you can choose, and you pay that cost on every single frame whether you ever edit it or not.

How much storage does each format really use?

Here's a realistic 2026 reference for a 12-48MP phone or camera shot. Exact sizes vary with resolution and scene detail, but the ranking never changes.

Format Typical size (per photo) Editing headroom Best for
HEIC / HEIF 2-3MB (12MP) Low Everyday shots, max storage savings
JPEG 3-6MB (12MP) Low Universal sharing, compatibility
HEIC (high-res) 5-12MB (48MP) Low-medium Detailed shots without RAW bloat
JPEG (48MP) 10-25MB Low High-res capture, wide compatibility
ProRAW / RAW 20-50MB+ High Serious editing, professional work

The gap is dramatic. Shooting RAW instead of HEIC can multiply your per-photo footprint by ten or more. Over a few hundred shots that's the difference between a couple of gigabytes and tens of gigabytes.

When is RAW actually worth the space?

RAW earns its size only when you'll use the data it preserves. Shoot RAW when:

  1. You edit seriously. You pull photos into Lightroom, Photos, or another editor and adjust exposure, color, and shadows.
  2. The lighting is hard. Bright skies over dark foregrounds, mixed indoor light, or sunsets benefit most from RAW's recovery range.
  3. The shot matters. A wedding, a once-in-a-lifetime trip, or a portrait you'll print is worth the storage.
  4. You want maximum quality for a few keepers, not your whole camera roll.

Shoot JPEG or HEIC instead when:

  1. You just want to capture and share. Screenshots, receipts, memes, quick snaps, and social posts gain nothing from RAW.
  2. Storage is tight. If your phone is already full, RAW will refill it fast.
  3. You won't edit beyond a filter. A JPEG handles light cropping and basic tweaks fine.

The practical rule: most people should default to HEIC/JPEG and switch on RAW deliberately for the rare shoot that needs it — not leave it running for every photo.

How do I set RAW or JPEG on my phone?

On iPhone, the format controls live in two places:

  1. Open Settings > Camera > Formats.
  2. Choose High Efficiency for HEIC (smallest) or Most Compatible for JPEG.
  3. To enable ProRAW, turn on ProRAW & Resolution Control (on supported Pro models) in the same screen.
  4. In the Camera app, tap the RAW badge at the top to switch ProRAW on or off per shot — leave it off by default and tap it on only when you need it.

On most Android phones:

  1. Open the Camera app and tap the Settings gear.
  2. Look for Picture format, RAW, or a Pro/Expert mode that exposes a RAW (DNG) toggle.
  3. Pick JPEG or HEIF for everyday shooting; enable RAW only inside Pro mode when you plan to edit.

Samsung, Pixel, and others place these under slightly different labels, but the logic is identical: RAW lives behind a Pro/manual mode, and the compressed format is the default for a reason.

Is it safe to switch formats or delete RAW files to save space?

Yes — switching formats is completely safe and only changes how new photos are saved; it never touches the ones you already have. Deleting old RAW files is also safe as long as you keep a copy of anything you still care about.

What your phone does natively: iOS and Android let you choose the format and will keep deleted photos in Recently Deleted (iOS) or Trash (Android/Google Photos) for around 30 days so you can recover mistakes. iOS also offers Optimize iPhone Storage under Settings > [your name] > iCloud > Photos, which keeps lighter copies on-device while full-resolution originals (including RAW) live in iCloud. None of this finds your oversized or duplicate RAW files for you.

What a tool like Cleanor adds: It scans your library on-device to surface your largest files, exact duplicates, and near-identical bursts — exactly where stray RAW and ProRAW shots hide — so you can review and batch-delete the heavy ones you'll never edit, instead of scrolling for an hour. Cleanor processes photos locally rather than uploading your whole roll.

What no app can do: Nothing can losslessly shrink a true 40MB RAW file down to JPEG size while keeping all its editing headroom — compression always trades data for size. And once the Recently Deleted window passes, a photo with no other copy is gone for good. So back up first, then clear. If you're deciding what's safe to remove, duplicate vs similar photos what to delete to free up space and storage full what should I delete first lay out a sensible order.

FAQ

Does RAW take more storage than JPEG?

Yes, by a wide margin. A RAW or ProRAW file is typically 20-50MB or more because it stores unprocessed sensor data, while a JPEG of the same shot is usually 3-6MB and a HEIC closer to 2-3MB. That's often a 10x or larger difference per photo, which adds up fast across a full camera roll.

Should I shoot RAW or JPEG to save space?

Shoot JPEG, or HEIC on iPhone, if saving space is your priority. Reserve RAW for the specific photos you intend to edit seriously, since that's the only situation where its extra size pays off. Most everyday snaps gain nothing from RAW but cost many times the storage.

Can I convert RAW to JPEG to free up space?

You can export a RAW file as a JPEG, which produces a much smaller copy, but the JPEG won't carry RAW's editing flexibility. If you keep both, you've saved nothing; the space is only freed once you delete the original RAW. Keep RAW only for shots you'll genuinely re-edit.

Is HEIC a good middle ground between RAW and JPEG?

For storage, HEIC is excellent: it stores JPEG-like quality in roughly half the size, so it's the most space-efficient everyday format on iPhone. It does not, however, give you RAW's recovery range for heavy edits. Use HEIC as your default and switch to RAW only when a specific shot needs serious post-processing.

Where to start

The fastest win is to stop the bleeding and then clear the backlog. First, set your camera to HEIC (iPhone) or JPEG/HEIF (Android) as the default and reserve RAW for deliberate shoots, so new photos stop eating storage at RAW rates. Second, clear the heavy files you've already accumulated.

For that second step, Cleanor for iOS scans your library on-device to surface your largest files, duplicates, and bursts — the stray RAW shots and redundant copies doing the real damage — and our clean up phone storage walkthrough lays out the full safe routine. If you're unsure what to remove first, start with storage full what should I delete first, and if duplicates are your bottleneck, duplicate vs similar photos what to delete to free up space shows what's genuinely safe to delete.
