# RAW to JPG — Extract Full-Resolution Embedded Preview

> Loft RAW to JPG is a free online converter that extracts the full-resolution JPEG your camera embedded inside a RAW file, entirely in your browser. It reads Canon CR2/CR3, Nikon NEF, Sony ARW, Adobe DNG, Fujifilm RAF, Olympus ORF, Panasonic RW2, and more, then pulls out the preview JPEG in one click — no upload, no software, no signup. Files never leave your device.

## What it does

- Extract embedded JPEG from Canon CR2, CR3
- Extract embedded JPEG from Nikon NEF, NRW
- Extract embedded JPEG from Sony ARW, SR2, SRF
- Extract embedded JPEG from Adobe DNG
- Extract embedded JPEG from Fujifilm RAF
- Extract embedded JPEG from Olympus ORF
- Extract embedded JPEG from Panasonic RW2
- Export to JPEG, PNG, or TIFF — pick the output container
- JPEG quality slider and chroma subsampling control
- Resize the embedded preview (native, medium, or full)
- Custom batch filename patterns with {name}, {n}, {date} tokens
- Per-file batch status (queued, processing, done, failed) with thumbnails
- Batch convert multiple RAW files — download as ZIP
- Instant — pure byte-scan, no WASM demosaic
- Browser-only — files never leave your device

## How it works

1. **Upload RAW file(s)** — Drop your CR2, CR3, NEF, ARW, DNG, RAF, ORF, RW2, or other RAW file, or click to browse. Up to 200 MB per file.
2. **Choose output format and options** — Pick JPEG, PNG, or TIFF. Set JPEG quality and subsampling, the preview size, and a filename pattern for batch output.
3. **Convert and download** — Click Convert. The tool extracts the largest embedded preview and re-encodes it to your chosen format. Single files download directly; batches are packaged into a ZIP.

## FAQ

### What RAW formats does this support?

The tool works with any RAW format that embeds a JPEG preview, which includes virtually all modern camera RAW formats: Canon CR2/CR3, Nikon NEF/NRW, Sony ARW/SR2/SRF, Adobe DNG, Fujifilm RAF, Olympus ORF, Panasonic RW2, Pentax PEF, Samsung SRW, and others.


### How does it extract the JPEG?

Camera RAW files always embed one or more full-resolution JPEG previews so your camera's LCD and software can display them quickly. This tool scans the RAW file's binary data for JPEG start (FF D8 FF) and end (FF D9) markers, then extracts the largest JPEG found. No demosaic or RAW decoding is performed — it simply pulls out what the camera already put in.


### Is the extracted JPEG full quality?

Yes. The extracted JPEG is the same file your camera embedded — it is the camera's own fully processed, full-resolution preview. It has not been re-encoded or compressed by this tool.


### Can I export to PNG or TIFF instead of JPEG?

Yes. Choose JPEG, PNG, or TIFF as the output format. JPEG keeps the camera's original bytes untouched at full size (zero re-encode, EXIF preserved); PNG and TIFF re-encode the extracted preview to a lossless container. You can also resize the preview and set a custom filename pattern for batch output.


### Will my files be uploaded to a server?

No. All processing is done by JavaScript running in your browser tab. Your RAW files never leave your device.


### What about full RAW development (demosaic)?

This tool extracts the embedded JPEG preview — instant and zero-loss. Full RAW development (LibRaw-based demosaic that processes the raw sensor data for maximum control over exposure, white balance, and tone) is planned as a future premium feature.


### Can I convert multiple RAW files at once?

Yes. Drop several RAW files and they are all processed. The extracted JPEGs are packaged into a single raw-previews.zip download.


## Tips

- **Works with any camera brand** — Canon, Nikon, Sony, Fujifilm, Olympus, Panasonic, Pentax, Samsung — all embed JPEG previews in their RAW files. Drop any format and it just works.

- **The JPEG is already there — extraction is instant** — Your camera embeds a full-resolution JPEG inside every RAW file for quick display on the LCD. This tool extracts it in milliseconds — no decoding or conversion needed.

- **Batch convert your shoot** — Drop an entire folder of RAW files and download a ZIP with all JPEGs. Ideal for quickly sharing a shoot before doing full RAW editing.


## Privacy — what we do not do

This tool runs entirely in the browser via WebAssembly. Your file never reaches a Loft Tools server. Specifically:

- **No upload.** The file bytes load into the browser tab's memory and process on your own CPU. Open DevTools → Network and observe zero outbound requests carrying file data while RAW to JPG — Extract Full-Resolution Embedded Preview runs.
- **No AI training on your file.** Loft does not train models. We could not train on a file we cannot see.
- **No content scanning.** No virus, copyright, or content-moderation pass against your file. The bytes are not accessible to us.
- **No server-side log of file contents, filenames, or EXIF metadata.** Cloudflare edge captures URL and truncated IP for abuse defense (standard CDN behaviour). Cloudflare Web Analytics records anonymous page hits, no cookies, no PII. Nothing about your file content reaches any log.
- **No retention.** Close the tab and the file leaves browser memory. No backups exist on our side because no copy ever existed on our side.
- **No account.** No email, no signup, no auth, no telemetry tied to you.
- **Offline-capable after first visit** (PWA). Once you've loaded a tool, it caches; later sessions work without internet. For high-sensitivity files, run the tool once online to warm the cache, then disconnect before processing.

Compare with upload-based services: each transmits your file to a processing server. Even over HTTPS, each has logs, retention windows, and subpoena exposure. Loft has none of these because the server architecture does not include your file.
