DNG to TIFF Converter

DNG (Digital Negative) is a raw image format created by Adobe as a standard file type for digital cameras. It holds the sensor data before it is turned into a finished picture, which gives the most editing flexibility. TIFF (Tagged Image File Format) is a raster format widely used in publishing and printing that stores finished pixels without lossy compression. DNG suits editing and archiving raw captures, while TIFF suits finished images, printing and moving files between programs without the artifacts JPEG compression can add.

Click the area labeled Click or Drag DNG Files Here, or drag files onto it. Each DNG appears in a list with its size and a Ready status. Click Convert to TIFF and the files are developed one after another. When a file is finished, a Download TIFF button appears next to it; click it to save the image with the original name and a .tiff extension. Clear All empties the list, and files already converted are skipped if you click Convert to TIFF again.

TIFF avoids the lossy compression JPEG uses to shrink files, which can leave artifacts and soften fine detail, especially after repeated saves. This converter writes uncompressed TIFFs, so every pixel of the developed image is stored exactly and you can open, edit and resave the file without generational loss. The TIFF is 8 bits per channel in sRGB, the same bit depth as a JPEG, so it suits retouching, layout and print handoff rather than heavy tonal edits, where a 16-bit export from a raw editor gives more room.

This converter develops each DNG with the camera's own defaults: the as-shot white balance, the file's color matrix and baseline exposure, and the default crop. It does not apply edits made in a raw editor. Use it when you need a TIFF straight from the raw file, for example to hand a neutral image to a retoucher or layout designer, or to open a DNG in software that does not read raw files. If you have already made exposure and color adjustments, export the TIFF from your raw processor so those edits are included.

It is normal for the TIFF to be much larger than the DNG. A DNG stores one value per pixel from the sensor, often with lossless compression. The converter's TIFF stores three full color values for every pixel with no compression at all, so its size is roughly width times height times three bytes. A 24 megapixel image comes to about 72 MB, and a 7008 by 4672 pixel file to about 98 MB. That is the trade-off for a file almost any program can open without decoding.

To some degree, yes. DNG files usually hold 12-bit or 14-bit data from the sensor, and this converter writes an 8-bit TIFF, with 256 levels per channel, after applying white balance and the sRGB tone curve. Highlights that clip in that rendering cannot be recovered from the TIFF, and heavy edits later may show banding in smooth gradients. For a TIFF that keeps the full tonal range, export a 16-bit TIFF from your raw processor, and use this tool's output for viewing, review and light retouching.

Yes. You can select several DNG files at once or drag a group onto the upload area, and add more before converting. Click Convert to TIFF and the files are processed one after another, each showing Processing until its Download TIFF button appears. Downloads are not automatic, so click each button to save the files you want. Because every DNG is developed on your own device and each TIFF is large, a long batch of high-resolution files depends on your computer's memory.

If a file shows Error, the tool could not read it, either because the file is damaged or not a standard DNG, or because your browser ran out of memory while developing a very large image. Close other tabs and try the file on its own. When the raw data is in a form the converter cannot develop, it automatically uses the largest preview image embedded in the DNG instead, so you may get a smaller, camera-rendered result rather than an error. Files without a .dng extension are not accepted.

Many smartphones can save DNG files, and the converter handles them the same way as camera DNGs. It develops both mosaic raw data and the already demosaiced linear raw data some phones produce, applying the white balance and color matrix stored in the file. Some phone DNGs keep their raw data in a compression format the tool cannot read; in that case it uses the preview embedded in the file. Either way you get a TIFF ready for desktop editing at the resolution the file provides.

No. The TIFF is written from the developed pixels, so camera details such as model, lens, focal length, aperture, shutter speed, ISO, GPS location and copyright are not carried over. The file records only its dimensions, color layout and a nominal resolution of 72 pixels per inch. Keep your original DNG alongside the TIFF so you always have the full sensor data and metadata record, and set the print resolution and copyright in your editing software when you prepare the file for delivery.
