Free Photo Editing Software That Works on Phone, Tablet and Laptop
Every workshop in Barga reaches the same moment on the first evening. The day's photographs are on the table alongside the wine, and someone asks what they should edit them with, because they are not paying Adobe every month for a hobby. A second question follows straight after. Will it also work on their partner's Android phone, the iPad and the old Windows laptop at home?
No single free photo-editing app supports every device, but two programs together cover a wide range. Snapseed offers a consistent interface across iPhone, iPad, and Android. Meanwhile, Affinity by Canva, free with a Canva account, works well on both Windows and Mac and offers features like layers, masks, and RAW support. For laptop users seeking a free alternative to Lightroom, darktable is an excellent choice for RAW photography.
That leaves the obvious question. If paid software manages one app across every device, why can't free options do the same?
Why no free photo editing software covers every device
Phone editors and desktop editors are built on different assumptions about screen size, file handling and processing power, and the free ones rarely try to bridge both.
A phone app is designed for touchscreen use, letting users work with one photo at a time and access files stored in the camera roll. In contrast, a desktop editor is optimised for mouse input, requires a folder of RAW files, and needs enough memory to manage multiple versions of an image at once. Developing a single program that effectively serves both platforms while ensuring compatibility across iOS, Android, Windows, and macOS can be costly to maintain. As a result, companies that offer this type of software typically charge for it, with Lightroom being a notable example.
Google Photos is the only free exception. Its editing tools are available on iPhone, Android, and any laptop browser, and the one-tap suggestions provide a good starting point. However, its editing capabilities are limited, and it works only with photos uploaded to your Google account, offering only basic support for RAW files.
So instead of teaching one compromised app, I teach two good ones and a single workflow that carries across both. Learn the order once, and only the buttons change.
On a phone or tablet, use Snapseed
Snapseed is the free photo editor I recommend for any phone or tablet, iPhone and Android alike. It costs nothing, has no adverts, adds no watermark, and requires no account.
In May 2026, Google released version 4.0, and for the first time, the iPhone and Android versions of the app share the same layout. This is significant because when a group consists of both iPhone and Android users, having a consistent interface means that one set of instructions can be used for everyone. As a result, no one wastes time during the session searching for a tool that may be in a different spot on their screen.
The app can open JPEG files from cameras or phones, as well as DNG files, which is the RAW format commonly used by smartphones. However, it does not support RAW files from Sony, Canon, or Nikon cameras directly, so photographers using these brands will need to rely on JPEG files or use a laptop for those images.
The recent redesign has received mixed reactions from long-time users. Now, Snapseed imports photos directly into the app instead of allowing users to open them from a folder. Additionally, some Android users have reported crashes when using the masking feature since the update. So, export your finished edits before trying more complex tasks.
On a laptop, use Affinity by Canva or darktable
On Windows or Mac, Affinity by Canva is the free editor with the most to offer, and darktable is the better choice if you shoot RAW and already think in Lightroom terms.
Affinity by Canva combines photo editing, vector drawing, and page layout into a single application. The photo editing capabilities support RAW files, layers, masks, and retouching, and the app can be used offline once you’ve signed in with a free Canva account. The generative AI tools are available through a paid Canva Pro subscription, but the features I'll teach don't rely on them. There is no mobile version, so this application is designed for laptop use. Also, if you decide to purchase software, DxO PhotoLab 10 lets you send files directly to Affinity with one click.
darktable is open source and works much like Lightroom Classic. It keeps a library of your photographs and records every edit as a set of instructions, so it never changes the original file, and you can always step back. It is dense on first opening, and I wouldn't hand it to someone who's never edited before without sitting beside them. For an experienced Lightroom user who has cancelled a subscription, it is the closest free match.
If a laptop will not install anything, Photopea runs in any web browser on Windows or Mac and opens Photoshop files. It is funded by adverts and cramped on a small screen, but it is a useful fallback for a locked-down work laptop.
My shortlist by device looks like this:
iPhone, iPad or Android, use Snapseed
Any device with a Google account, use the Google Photos editor for quick fixes
Windows or Mac laptop, use Affinity by Canva
Windows or Mac laptop with RAW files, use darktable
A laptop that will not install software, use Photopea in the browser
The order of work matters more than the app
Whichever free photo editing software you choose, edit in the same order every time, because each step changes how you judge the next.
Straighten the horizon, then crop.
Set the overall brightness first, then contrast.
Adjust colour lightly, starting with white balance, then saturation.
Fix local problems, such as a dust spot or a bright patch in one corner.
Export a full-size copy for printing or a smaller one for sharing.
Cropping first means every later adjustment is judged on the picture you are actually keeping. Setting white balance before saturation stops you from pushing colour to compensate for an uncorrected cast. These five steps work the same way in Snapseed, Google Photos, Affinity and darktable.
Where to start
Pick the device you actually edit on, install the matching app and work through those five steps on a photograph you already like. You will learn more from one image taken through the whole sequence than from ten given a filter.
If you reach the point where you want one catalogue across every device, or the best possible RAW conversions, that is where paid software earns its keep. I cover Adobe Lightroom and DxO PhotoLab in my companion post. Try the free route first and let me know in the comments which app you settled on.
