Photo Editor Without AI: GIMP and Krita Ship None (2026)

Short Answer

GIMP and Krita ship no artificial intelligence (AI) features at all, so either one is a photo editor without AI in the strictest sense. In the guides we publish here we go by what each project documents rather than what its marketing page claims. Every quote below comes from the project's own site as published on 2 September 2026.

GIMP stands for GNU Image Manipulation Program, runs under the GNU General Public License, and costs nothing. Krita's own feature page says it "is, and will always be, free software" and lists no generative tools. Both run entirely on your machine, so nothing you open leaves the computer. For raw photos the answer is darktable or RawTherapee. darktable calls itself "an open source photography workflow application and raw developer" and ships under GPL 3.0. Neither site mentions AI or machine learning anywhere.

"Without AI" means two different things to two different readers. The tools sort into a different order depending on which meaning you hold.

What AI Free Means in a Photo Editor

Two very different things get called AI inside a photo editor, and only one of them invents pixels that were never in your file. A segmentation model looks at your image and labels each pixel as subject or background. A generative model produces new pixels from a text prompt or from surrounding content. One-click background removal is the first kind. Generative fill is the second.

Readers most often treat those two as one request. Someone who wants no AI because they distrust invented detail is fine with a segmentation cutout, since every pixel that survives came out of their own photograph. Someone who wants no AI because they do not want a neural network touching their files at all is not fine with it, and needs the manual tools instead.

The third question is whether the file is uploaded at all. digiKam ships AI classification and states on its own site that "All AI-powered tools run only on your computer." Photopea routes its AI work through Dezgo, a third-party service, which means an upload. Local AI and cloud AI are not the same risk. Treating them as one sends people to the wrong tool.

Photo Editors Without AI Ranked by Exposure

Five of the editors we checked publish documentation with no AI feature in it. The table is ordered by how much of a model your file passes through, from none at all to a cloud service tied to your account.

Paint.NET deserves a note, because its published roadmap is unusually explicit about what is coming. That plan covers version 5.2 in the second half of 2026 and version 6.0 in 2027, and neither entry mentions AI, machine learning, or generative tools. That is a Windows editor you can hand to a teenager without a lecture.

Affinity is the odd one out and the one worth a second look if you want a full design suite. Its own site says every tool in the Pixel, Vector and Layout studios is free to use with no payment needed. The AI tools, including generative fill and background removal, arrive only with a Canva premium plan. Skip the subscription and the generative features never appear in the interface at all.

Pixelmator Pro, now owned by Apple, sits in the middle. Its AI runs on your Mac, so nothing uploads, but Super Resolution genuinely reconstructs detail rather than interpolating it.

Krita's community forum applies a stricter rule than the software does. In an October 2023 policy post, its moderators wrote that "we will no longer allow posts that promote AI tools. This includes plugins whose objective is to add generative AI to Krita." The program still loads third-party plugins that add image generation, so the forum rule is about what gets promoted rather than what the code allows.

The same question arrives one step earlier, at capture. Open Camera calls itself "an Open Source Camera app for Android™ phones and tablets" and is "released under the GPL v3 or later". Its site names no AI or machine learning feature anywhere. It gives you manual controls, exposure bracketing and raw capture, without the scene-detection and face-beautifying models that ship on most stock camera apps.

Interior design is the one category where we could not find a clean answer. Every room visualiser we checked builds the feature on a generative model and publishes no documented way to switch it off. Draw the plan in a traditional floor-plan tool instead. Sweet Home 3D describes itself as "a free interior design application which helps you draw the plan of your house, arrange furniture on it and visit the results in 3D". It ships under the GNU General Public License and names no AI feature on its site.

How to Remove a Background Without an AI Model

GIMP's Foreground Select tool cuts a subject out of its background using matting algorithms, with no trained network involved anywhere. The GIMP documentation gives five steps.

1. Roughly select the object with a little background around it.
2. Press Enter to build the mask.
3. Draw a line through the foreground with the brush.
4. Toggle the preview to check the result.
5. Click Select to finish.

Two engines are offered, Matting Levin and Matting Global. The docs say Matting Levin "usually gives the best results, but is slower, especially on larger images when there are large unknown areas". Switch to Matting Global on a big file if the preview crawls. Windows users may have no choice: the same page warns that "Matting Levin has been temporarily removed on Windows due to crashes. When it is available, it is the default."

For a hard-edged product shot, the Paths tool beats both. You click your way around the object, close the path, convert it to a selection, and delete. It takes longer than a click, and it gives you an edge you chose rather than an edge a model guessed at. Krita's selection tools and quick mask do the same job for illustration work, and Photopea's lasso, polygonal lasso and magic wand are available without touching its AI menu.

Nearly every one-click background remover on the market is a segmentation model, including Photopea's Remove BG and the one inside Affinity. The open-source rembg project makes this visible: its README lists selectable models including U-2-Net, ISNet and BiRefNet, each a neural network trained to separate subject from background. None of them writes new pixels. If your objection to AI is invented content, these are safe and fast. If your objection is the model itself, Foreground Select and the Paths tool are your two options, and both are free.

What a No AI Upscaler Can and Cannot Do

Classic interpolation enlarges an image without inventing a single detail, and it still ships in every serious editor. ImageMagick exposes it directly through the -filter option, which accepts Point, Box, Triangle, Hermite, Gaussian, Cubic, Catrom, Mitchell and the windowed filters including Lanczos. Its documentation states the default plainly: "If you do not select a filter with this option, the filter defaults to Mitchell for a colormapped image, an image with a matte channel, or if the image is enlarged. Otherwise the filter default to Lanczos." Running magick in.jpg -filter Lanczos -resize 200% out.jpg gives you a clean double-size file in under a second.

GIMP offers the same choice in the Scale Image dialog, and its docs describe each one in a sentence. Of None they say: "The color of each pixel is copied from its closest neighboring pixel in the original image." Linear averages the four closest pixels. Cubic averages the eight closest. NoHalo and LoHalo are the newer pair, and GIMP's interpolation reference publishes two rules for them that disagree. Its instruction says to "Use the NoHalo method when you downscale an image to less than a half of the original size and the LoHalo method when you do not reduce the size much (rotate, shear)." A note further down the same page, from Nicolas Robidoux, who wrote both filters, recommends LoHalo for reductions and NoHalo for enlargements and rotations. We follow the Robidoux note, because he wrote the code. Try both on your own file, since GIMP publishes the two statements side by side and resolves neither.

Pixel art is the one case where the ordinary advice inverts. Lanczos will blur a sprite into mush, so use None or Point instead and keep the hard edges. For a smoothed enlargement that respects the original shapes, use xBRZ. It is a dedicated pixel-art scaler under the GNU General Public License v3, and emulator front-ends have shipped it for years.

The arithmetic decides whether interpolation is enough for you. Take a 1,000 pixel wide photo and scale it to 2,000 pixels with Lanczos. You now have four times as many pixels and exactly the same amount of information, spread thinner. Licence plate text that was unreadable at 1,000 pixels is still unreadable at 2,000. A generative upscaler will hand you readable text, and that text is a guess. Apple's own guide to Super Resolution in Pixelmator Pro puts it as enlarging "any photo while preserving sharpness and detail", which is a different promise from copying pixels around.

The same split applies to anything sold as a quality enhancer. Unsharp masking, contrast curves and wavelet noise reduction are arithmetic you can audit, and darktable and RawTherapee are full of them. A one-click enhance button that fixes a blurred face is not.

What Adobe and Canva Publish About Your Files

Adobe's Terms of Use, dated 3 October 2025, address model training in section 2.2: "We will not use your Local or Cloud Content to train generative AI models except for Content you choose to submit to the Adobe Stock marketplace". Its separate Content Analysis FAQ, last updated 4 June 2026, repeats the point and adds an opt-out: "You are in control over whether Adobe may analyze your content that is processed or stored on our servers when using Creative Cloud and Document Cloud apps to improve our products and services." The FAQ names the setting but does not contain it. The switch sits in your Adobe account privacy settings.

Generative Fill is a separate question from training. Adobe's Photoshop documentation, last updated 18 June 2026, shows a model picker. It offers Firefly Image 5, Firefly Fill and Expand, and Firefly Image 1, plus partner models from Google and Black Forest Labs. Pick a partner model and your selection goes to a company that is not Adobe.

Canva's AI Product Terms, effective 26 June 2026, are blunter about the handoff: "You agree and acknowledge that your Input may be shared with our Technology Partners, for the specific purpose of providing you with the functionality." The same document names the control: "Your Privacy Settings control whether Canva and our Technology Partners, may use your data to improve our AI services for everyone." Canva owns Affinity, so those terms are the ones that govern Affinity's AI tools too. Leave the Canva plan unpurchased and the question does not arise.

Who a Photo Editor Without AI Does Not Suit

Event and wedding photographers running thousands of high-ISO frames a week should not go fully AI free, because the time cost is real. Lightroom's denoise and Pixelmator Pro's Super Resolution turn a salvage job into a two-minute fix, and no wavelet slider in darktable matches them on a badly underexposed reception shot. The sane middle is to split the work. Keep one paid tool for rescue frames, and switch content analysis off in your Adobe account privacy settings. Do culling, colour and export in darktable, where no model touches the file.

The same applies to anyone whose client requires a specific PSD round-trip. Photopea opens PSD files well and Affinity handles them, but if a studio has a Photoshop-only pipeline, an editor swap is a fight you will lose. Turn the AI features off inside the app instead, the way you would turn off Apple Intelligence on a Mac.

What Would Change Our Answer

Three specific events would move GIMP and Krita off the top of this list.

1. Either project merges a generative feature into the core program instead of leaving it to third-party plugins. That would drop them into the same tier as Photopea.
2. Affinity makes a Canva account a requirement for non-AI work. That would take the free suite off the table for anyone avoiding cloud accounts.
3. A paid vendor ships a documented offline build with the model files removed, verifiable by inspecting the install. A professional could then keep a familiar toolset and give a client a straight "no".

None of the three has happened as of 2 September 2026. We recheck the release notes and terms pages on each pass and update this page when one moves.

Verdict

Install GIMP if you edit photographs, Krita if you paint or draw, and darktable if you shoot raw. All three are free, all three run offline, and none of them documents a single AI feature. Add ImageMagick if you resize in bulk, because one command line beats any web upscaler for a batch of 400 files. Keep Paint.NET on the list for Windows machines where GIMP feels heavy.

If you are stripping AI out of the rest of your setup, our AI-free apps index collects every category we have checked. That includes browsers without AI, phones without AI and note-taking apps without AI. Two related guides sit next to this one: how to spot AI slop, and which AI art detectors hold up on real images.

If your wider worry is what happens to your files, start with protecting your privacy online. Download GIMP from its own site and make it your default photo editor without AI before your next edit.
