Whereas, a “RAW” image format store every single bit of data from your camera sensor. You can use this format to modify your photo to a greater extent.

But, not all photo editing programs can open and edit a RAW file.

Therefore, we brought you the 10 best free photo editors that you can use to enhance your RAW image.

Without further ado, let’s get started.

1. Darktable

2. Rawtherapee


RawTherapee is a free open source photo editor that edits RAW files. It provides deep photo color correction, high dynamic range (HDR) tone mapping, histogram matching, and other useful picture adjustments. Besides, it offers pre-processing, pattern noise, and chromatic aberration correction for your RAW images.

It is best to use it for quick cataloging of your images. Besides that, it does have some essential tools from photoshop and presents a more in-depth color correction option.

It supports a variety of images from different cameras. And developers are adding more formats to it frequently. However, there are some adjustments that Rawtherapee lacks. Some essential features like layers are not available in Rawtherapee and stop it from becoming a full-fledged photo editor.

Rawtherapee does come with some drawbacks. The processing speed could have been better as compared to Photoshop and Lightroom. The change in value does not reflect in real-time. Although it is not a problem if your editing pictures for fun, but it can be an issue if you are doing it for business. Also, the user interface is quite confusing. Besides, there aren’t many free tutorials for this editor available for learning. A new user might find it challenging to get a hold of it.

If you are using open-source photo editors for a while now, then you can give Rawtherapee a shot. We would not recommend a beginner to start their journey from this editor. Lack of free tutorials and information regarding this editor makes the learning curve gradual.



GIMP features some professional-quality functions that can easily rival giants like Photoshop. Besides, it is an open-source, free image editing platform. It is a full-packed solution for photographers, graphic designers, and illustrators.

It has a standard User interface that adheres to the high-end graphics editor layout. The editor has three parts: toolbox, main editing area, and layer, paths, undo, and channels.

Although GIMP being free lacks the intensity of the commercial photo editor, it provides all the necessary commands, editing features, and tools. It has the layers feature like photoshop that allows you to work nondestructively.

GIMP allows the user to improve productivity via many customization choices and its support for third-party plug-ins. It is the most maintained open-source photo editor of all. Developers work continually in the betterment of GIMP’s source code. 

Also, it has an in-depth help and support. There are several free youtube tutorials that you can watch. Therefore it has a steep learning curve. That means even a beginner won’t find it challenging to learn the functions. 

GIMP does not have an inbuilt RAW photo feature. But you can install the free UFRaw plug-in. You can also use UFRaw individually to open RAW files. It supports almost every RAW file format. Although it lacks in-depth editing features, therefore using it as a GIMP plug-in delivers excellent results. It is the best free, open-source photo editor in general.

4. Capture One Express for Sony and Fujifilm


If you are using a Sony or Fujifilm camera to click your RAW photo, then you should use Capture One Express to process your images.

Capture One Express is the free version and has the full editor’s cataloging tools. That means, once you’ve imported your raw pictures into the catalog, you can order them by folder or into Albums and Smart Albums. Moreover, you get a full collection of search and keyboarding functions too.

The editing tools are simple to understand and effective. You can find ‘tool tabs’ for Quick adjustments, Color, Exposure, Lens corrections, Adjustments (Styles and Presets), Details, and Metadata. Each tool tab possesses collapsible adjustment panels. So the Quick tool tab, for example, has Exposure, High Dynamic Range (shadow and highlight adjustment), White Balance, Black & White, and Clarity panels. 

For downside, you don’t get the advanced controls and local adjustments like Pro version in the free one. Therefore, there is only so far you can do with your raw images before you need to swap to another image-editor. That is for in-depth effects, layers, and local enhancements. Besides, it supports only Sony and Fujifilm RAW files in the free version. That means you can not use it with other cameras.

However, Capture One Pro can still produce the best high-quality, processed raw files. Therefore, you can import them to Photoshop, Elements, Affinity Photo, or any other photo editor of your choice. We have discussed better free Photoshop alternatives in further sections.

Capture NX-D has no browsing and batch conversion tools. It’s quite confined compared to other editors, but it may be sufficient for most of your needs. It doesn’t have cataloging tools – there’s no centralized database for organizing and searching within your whole photo collection. Still, you can skim the folders containing the photos on your hard disk, and for many photographers, that’s acceptable.

Unlike other raw conversion editors, Capture NX-D does not make changes to your original raw files, or JPEG images. Its adjustments are saved only as processing directions in data stored alongside your photos. However, to make the change permanent, you have to use the Convert files button. By doing so, you create a new JPEG or TIFF photo with the adjustments applied.

You don’t have to edit and transform each photo individually. Instead, you can use the batch processing option to convert an entire folder. As a result, it applies adjustment parameters to all images in the folder. Also, you can perform individual adjustments to each photo if you like. Moreover, you are free to create a new folder with different filenames while doing batch processing.

For the downsides, Nikon Capture NX-D does not support other RAW file formats. However, you can carry out advanced and wide-ranging adjustments, from automatic lens corrections to detailed selective color shifts. Additionally, it can make your images as pleasant as possible. But, it would have been better to provide more image editing functions. Apart from that, the editor freezes quite often.

  1. All these opensorce tools are terrible slow, when You manipulating with large RAWs. Poor denoise algoritm, slow image loading, slow conversion, simply every is slow.
    When I click on the image in Rawtherapee, it took second to open it in the editor. In AfterShot – image is in the editor almost instantly.
