The 10 best free photo editors
It’s here! Our detailed list of the best open source photo editors. We’ll begin with the strongest and work our way down to the easiest and most specialized.
1. GIMP stands for “GNU Image Manipulation Program.”

GIMP is the best free picture editor there is, without a doubt. It is the world’s most powerful, well-known, and flexible open source photo editor. It’s been the best free option to Adobe Photoshop for more than 25 years and has grown into a huge set of tools that can do any job you give it.
Who Should Get It:
The Would-Be Professional: GIMP is a great way to learn the skills needed for professional photography and graphic design without having to pay a lot of money.
The Small Business Owner: Create your own banners, marketing materials, and graphics for social media and your own website without hiring a graphic artist or forking over a monthly payment for software.
The Digital Artist: If you’re more into painting, then Krita is better, but GIMP has some great drawing tools that make it an easy choice for artists who work with photos, too.
The Student: This software is good for art, design and photography students in need of proper tools and who don’t want to spend any money.
What’s Great About It (Key Strengths):
This program is very powerful and has all the professional tools you could want. It has advanced layers with masks, strong selection tools, color correction curves, filters, and a lot more.
You can change just about everything to get it working to your requirements. There are even themes you can get for it that will make it look and feel more like Photoshop.
Very Powerful: The real strength of it comes from the thousands of free apps that people have made for it. You can add new filters and functions that some paid programs don’t even have.

Opens Almost Any File: It can open and change files from a lot of different apps, even Photoshop PSD files.
Making a “double exposure” effect is a fun first project
Open a headshot picture of a person. The background should be simple and clean.
Open a second picture that shows a scenery or cityscape, like a forest of trees or the skyline of a city. Copy this picture.
Look at your face picture again. Put the scenery picture on a new layer that you just made.
Select the person and right-click on the portrait layer in the layers box. Then, choose “Alpha to Selection.” This will make “marching ants” follow the person.
Before you press the Delete key, choose your landscape layer and go to the menu. Then, click Select > Invert. This will get rid of everything in the scenery that isn’t the silhouette of the person.
Remove all of your choices (Select > None). Now, change the “blending modes” for the landscape layer in the layers panel. “Screen” or “Lighten Only” modes often make the scenery look like it’s inside the person, which is a beautiful and artistic effect. This method is very famous and stylish!
The learning curve is steep. There are so many tools and choices in GIMP because it’s very powerful. With time and effort, you will reap the rewards.
2. Krita

If you want to make digital art, Krita is the best program you can get for free. It is known around the world as one of the best programs for digital painting and drawing. It is also a great and very powerful open source image editor that anyone can use to give their photos a creative, artistic touch.
Who Should Get It:
Krita: For the Digital Artist. If you wish to make art rather than edit images, Krita is the best program you can get for free, an internationally known program for painting and drawing digitally.
For the Creative Photographer: Great if you consider photography only the starting point for your art.
That’s right, Krita’s fantastic brush engine will allow for high-end skin smoothing and retouching techniques such as “frequency separation.”
The Fantasy Artist: The best tool for combining photographs with hand-drawn fantasy-themed imagery.
Who it’s for: Anyone who likes to draw.
What’s Great About It (Great Feature):
The legendary brush engine: Krita packs more than 100 professional-quality brushes in its free package, all of which come with it right out of the box and all of which can look like charcoal, ink, oil paints and pastels, etc.

While “painting” on a picture to add light, shadow, or color, this gives you a lot of control.
Excellent Layer Management: Krita’s layer system is up-to-date and strong. When you work with paint layers, filter layers, and transform masks, you can do so without editing the original picture in any way.
Made for Artists: Krita is made to feel natural and easy to use for creative work. Its tools and clean interface are all meant to do this.
Making a “watercolor painting” out of a picture is a fun first project
Open a picture you like, like a scenery or flower picture.
Making a copy of the background layer will give you another one to work on.
Find Filter > Artistic > Watercolor in the menu. Slide the bars around until you get an artistic, soft look that you like.
You can find a paper texture picture online to make your pictures in open source photo editing look even more real. Search for “watercolor paper texture” to find it.
Place this image of a paper pattern on top of everything else, as a new layer. Change the blending mode of the paper texture layer to “Overlay” or “Multiply”.
The paper will blend in with your painted picture, creating a real folk art effect. This is the creative kind of open source photo editing that Krita does really well.
The learning curve is not so steep. It is easier to learn than GIMP, especially if you are already knowledgeable about art. It still takes time to get good at everything.
3. Darktable

With darktable, you can process photos on your computer like a professional, and it’s free. A lot of people think it’s the best open source photo editor for photographers. For organizing and creating RAW files from high-end cameras, it is the best. It’s not made for general graphic design.
Who Should Get It:
Serious Amateur Photographer: If you have a DSLR or compact camera and shoot in RAW, darktable is the best tool for getting the most out of your photos.
The Event Photographer: If you take a lot of pictures at events like weddings, sports games, or shows, darktable’s organizing and batch processing features will save you a lot of time.
The Landscape Photographer: tools for changing dynamic range, color, and level of detail make scenes look epic and dramatic.
What’s Great About It (Key Strengths):

Professional RAW Processing: darktable uses the best picture data, which lets you make changes to colors, exposure, and details with amazing accuracy.
Fully Undeletable: Your original photos are never, ever changed. You can change or remove any edit at any time. It’s just a list of steps.
Open source photo editing has tools for organizing your photos: You can organize libraries of photos using star ratings, color labels, keywords and powerful search filters in open source photo editing.
Advanced masking is also easy in open source photo editing: It’s easy to make changes to some part of a photo. For instance, you could make the sky a deeper blue or brighten the subject’s face.
“Day for Night” is a fun first project
Open any picture of a scenery shot on an appropriately cloudy but still bright day, and then go to the “darkroom” and under “Exposure,” drag the slider all the way down to the bottom. The entire dark scene will look like night.
Track down the “Color Balance RGB” part. This is a strong tool for professionals. Use the color wheel on the “Master” tab to make the whole picture a deep blue or cyan. It will look and feel like a classic movie “night” with this.
Now comes the magic. Track down the “Tone Equalizer” part. Click on a bright part of the sky with the eyedropper tool. First, move that part of the curve up on the Tone Equalizer’s graph. This will make the “moonlit” sky brighter while leaving the ground dark. You’ve just turned daytime into night!
The learning curve is steep. Darktable is a very complicated tool made for photographers. It takes a long time to learn how to use its features and workflow.
4. Raw Therapee

Like darktable, RawTherapee is a top-notch program for working with RAW pictures. This makes it one of the best candidates for the title of best open source photo editor. The picture quality is really important to some people. They want to be able to control everything.
The picture editor is for photographers who pay attention to details and love to mess around with settings to get the best results.
What makes it unique: It is famous for having complex algorithms that can pull out beautiful details from pictures. You’ll like how powerful this open source image editing software is if you like to zoom in to 400% to make sure the picture is clear.
5. DigiKam

DigiKam knows how to keep things in order. Its main goal is not to be an open source photo editor, but to be the best photo management app in the world. It’s meant to make even the most disorganized picture collections look better.
The picture editor is for people who feel like they cannot keep track of their photos. It works great for family historians, amateur photographers and anyone else who wants to find any picture they have ever taken.
