Editing photos on a Chromebook works through three routes: the native Gallery app, web editors like Photopea, and Android or Linux apps for pro work.
Most Chromebooks can edit photos the moment you open the lid — the Gallery app built into ChromeOS handles cropping, lighting, and rotation without a single download. Learning how to edit photos on a Chromebook beyond these basics reveals three routes that cover every skill level: the native app for quick fixes, web-based editors that rival desktop software for serious edits, and Android or Linux programs for professional-grade work.
What Can the Native Gallery App Do?
The Gallery app (previously called Photos) on ChromeOS handles everyday edits like cropping, rotating, adjusting brightness and contrast, and applying lighting filters — all free and built into the operating system. On ChromeOS 115 and later, additional AI-powered tools appear, including “Edit with AI” for background expansion, object erasing, and making stickers from photos.
These AI features are currently limited to select devices. Google’s documentation lists the Lenovo Chromebook Plus (14″, 10-core) as one model where “Expand Background” and similar tools are officially available. Users on other Chromebooks will see the standard editing toolbar without the AI section.
The Gallery app supports JPEG, PNG, WebP, and GIF files. WebM video files cannot be edited here — those need a different tool.
Web-Based Editors Offer Desktop-Class Power
Web editors run entirely inside Chrome and require no installation. Three stand out for Chromebook users.
Photopea (photopea.com) is a free browser-based editor that mirrors Adobe Photoshop’s interface and file format support. It handles PSD, XCF, and Sketch files, supports layers and masks, and works with RAW images. Almost anything you can do in Photoshop translates directly to Photopea.
Polarr offers a free tier for basic exposure, curves, and sharpness adjustments, plus full RAW file support. Its browser app is lightweight and fast — ideal for quick color grading.
Pixlr provides a free version with crop, resize, and basic color tools. The interface is simpler than Photopea’s, making it a good middle ground for users who found the Gallery app too limited but don’t need a full Photoshop clone.
All three process images on their own servers. Avoid uploading sensitive personal photos to any web-based editor you don’t trust.
Android and Linux Apps for Serious Work
For the heaviest editing jobs, Android apps from the Play Store and Linux programs bring full desktop capabilities to ChromeOS.
Adobe Lightroom runs as an Android app on Chromebooks that support the Play Store. The free mobile version handles exposure, color grading, and preset effects. A subscription unlocks masking, healing brush, and cloud syncing. Performance depends on the Chromebook’s RAM — older models with 4GB or less may stutter on large RAW files.
Snapseed, also an Android app, is completely free and offers selective adjustments, curves, and a useful “healing” tool for removing objects. Its interface is touch-first, so it works best on touchscreen Chromebooks.
GIMP is the heavyweight open-source option, installed through the Linux (Crostini) environment. It matches Photoshop in layer-based editing, color correction, and plugin support, and it costs nothing. The trade-off is the setup: Linux must be enabled, and the interface feels dated compared to modern editors.
Photo Editing Methods Compared
| Method | Best For | Limitations |
|---|---|---|
| Gallery (Native) | Quick crops, rotation, lighting fixes | No layers, no RAW support, AI limited to Plus models |
| Photopea (Web) | Full layer editing, PSD files, advanced compositing | Requires internet; UI dense for beginners |
| Polarr (Web) | RAW photo development, color grading | Free tier is basic; paid unlock needed for full tools |
| Pixlr (Web) | Simple touch-ups between Gallery and full editors | Ads in free version; no RAW support |
| Lightroom (Android) | Professional color work with presets | Pro features require subscription; RAM-heavy |
| Snapseed (Android) | Selective edits, object removal on touchscreens | No desktop-style interface; touch-only |
| GIMP (Linux) | Full Photoshop-equivalent work for free | Requires Linux setup; steep learning curve |
Editing a Photo Step by Step in the Gallery App
Open the Gallery app from the Launcher. Navigate to the folder containing your photo — it will typically be in Camera, Downloads, or My Drive. Double-click the photo to open it in the editor.
For cropping, click the Crop & rotate icon at the top. Drag the handles to frame your subject and click Apply.
For lighting adjustments, select the Lighting filters icon. Drag the Brightness and Contrast sliders until the exposure looks right.
To save your work, click Save in the top right corner to overwrite the original, or choose Save as to keep a copy alongside it. The saved photo appears in the same folder with your adjustments applied — that tells you it worked.
Using Polarr for Web-Based Edits
Navigate to polarr.com in Chrome. Click Open Polarr and select Upload Photo from your files. The editor loads your image in the browser window — RAW files are supported and appear with their full dynamic range.
Use the Exposure slider to brighten or darken the whole image. The Curves tool gives finer control over shadows, midtones, and highlights independently. The Sharpness slider pulls out detail in landscapes and product shots.
When you’re finished, click Export and choose the file format and quality. The exported file lands in your Downloads folder, ready to use.
Google’s official guidance recommends Polarr as a free web editor for Chromebook users who need more than the Gallery app provides. ChromeOS photo editing documentation covers this and the native Gallery steps in detail.
How Do You Install GIMP on a Chromebook?
GIMP requires the Linux environment on your Chromebook. Go to Settings > Advanced > Developers and turn on Linux (Beta). The system downloads the container and prompts you to set a username — this takes a few minutes.
Open the Terminal app (listed under Linux apps in the Launcher). Type the following command and press Enter:
sudo apt-get install gimp
The terminal downloads and installs GIMP along with its libraries. When the prompt returns, close the terminal and launch GIMP from the Launcher under Linux apps. GIMP’s multi-window interface opens, ready to load images — the install finished correctly.
Pick the Right Editing Tool for Each Job
| If You Need To | Use This | Why It Wins |
|---|---|---|
| Crop and brighten a single photo | Gallery app | Zero setup, built into every Chromebook |
| Edit a PSD file from a designer | Photopea | Full layer and format support in a browser tab |
| Process RAW photos from a camera | Polarr or Lightroom | Native RAW support with color grading tools |
| Remove an object from a photo | Snapseed or GIMP | Healing tool and clone brush available |
| Work with layers and masks for free | GIMP | Desktop-class editing with zero cost |
Each route serves a different part of the editing spectrum. The Gallery app handles the quick jobs that take ten seconds. Web editors like Photopea cover everything from casual touch-ups to production work without using local storage. Android and Linux apps fill the gaps when you need specialized tools — RAW processing, object removal, or layer-based compositing — and they run on the hardware you already own.
