RAW to JPG Converter
Convert RAW to JPG in your browser. The camera's embedded JPEG preview is what gets converted, not the sensor data; it matches what the camera showed on its screen. No raw development happens here. You get a standard JPEG at the quality you choose. Nothing is uploaded.

How to use RAW to JPG
- 1
Add your RAW files: drop them here, choose them, or paste from the clipboard.
- 2
Set the quality. 85 to 92 looks identical to the original for most photos; 70 to 80 saves much more with little visible change.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.
- 4
Download the .jpg files one at a time or together as a ZIP.
Why use Aback Images for raw to jpg
Where the JPG goes next
JPG opens in every operating system, browser, phone, photo kiosk and image editor.
JPG next to RAW
The JPG is made from the camera's 8-bit preview, so it is a small fraction of a 20 to 80 MB raw file.
A second JPEG generation
The pixels come from the JPEG preview the camera embedded in the RAW, so they have been compressed once already; keep the quality at or above the default.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
RAW vs JPG
What changes from RAW to JPG
Encoding: the RAW uses uncompressed, lossless JPEG or vendor-specific coding of the sensor data, depending on the maker; JPG uses lossy DCT coding in 8×8 pixel blocks, with colour usually stored at half resolution, and the download is a standard JPEG at the quality you choose.
Bit depth: 12 to 16 bits per channel in the RAW; JPG allows 8 bits per channel, and the JPG written here has 8 bits per channel. The sensor's 12 to 16 bits are not used: the camera's 8-bit preview is converted.
Colour: camera-native RGB from a colour filter mosaic in the RAW; JPG supports YCbCr shown as RGB, greyscale, or CMYK from print software, written here as 8-bit sRGB.
Metadata: the RAW can carry EXIF and vendor maker notes, almost always with an embedded JPEG preview; JPG can carry EXIF (camera, date, GPS), XMP, IPTC and an ICC profile in APP segments, but nothing is copied across.
About RAW
Camera RAW files (CR2, CR3, NEF, ARW, DNG, ORF, RW2, RAF and others) hold the unprocessed sensor data from a camera along with an embedded full-size JPEG preview rendered by the camera.
.RAW is an extension rather than one format. Panasonic and Leica compacts wrote TIFF-like .RAW files before Panasonic moved to RW2, and scanners and scientific cameras use .raw for headerless dumps with no width, height or layout recorded, which nothing can read without being told those values.
RAW files usually come from older Panasonic and Leica compacts that saved .RAW, and scanners or scientific cameras that use the extension for pixel dumps.
About JPG
JPEG is the universal photo format. It compresses by discarding fine detail the eye is least sensitive to, which makes photos small but blurs sharp edges and text if pushed too far.
A JPEG starts with the bytes FF D8 and is a run of marker segments: APP1 carries EXIF and often a thumbnail, APP2 an ICC profile, DQT the quantization tables that decide the quality, and SOS the compressed scan, which ends at FF D9.
When converting RAW to JPG makes sense
JPG is the better choice for photographs that need to open anywhere, while RAW suits editing in Lightroom, Capture One or darktable.
JPG strengths: Opens everywhere: every browser, phone, camera, printer and app; Small files for photographs; Adjustable quality from tiny to near-lossless. Drawbacks to weigh: No transparency; Lossy: every re-save loses a little more; Blocky artifacts around text, logos and sharp lines.
Limitations
- A headerless .raw pixel dump has no preview and no size information, so it cannot be converted here.
- JPG has no transparency and no animation; it is the safest choice when a file must open on any device or upload form.
- Each time a JPG is edited and saved again it loses a little more detail, so keep your original for further editing.

Frequently asked questions
Does converting RAW to JPG lose quality?
JPG is lossy, so detail the eye barely notices is discarded to save space. The RAW's preview is a camera JPEG already, so keep the quality high to avoid stacking artefacts. The sensor's 12 to 16 bits are not used: the camera's 8-bit preview is converted.
Does this process the RAW sensor data?
No. Camera RAW files carry a JPEG rendered by the camera when the picture was taken, and that is what gets converted, so the result matches what you saw on the camera screen. For full development (white balance, highlight recovery, lens corrections) use a RAW editor.
What quality should I choose for JPG?
85 to 92 looks identical to the original for most photos. 70 to 80 saves a lot more with little visible change. Below 60, blocking appears around edges and in skies.
Which apps open JPG files?
Every operating system, browser, phone, photo kiosk and image editor.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
