Like most of us, you likely have dozens, if not hundreds of pictures stored on your phone or your camera's SD card. But are you making the most of them? Most of them probably look okay, but with a free photo editor and a little time you can transform them into something amazing.
Whether you're looking for a total Photoshop alternative that gives you fine control over every minuscule detail of your photos, or a basic Instagram-style free photo editor that offers a range of one-click filters, you’ll find something interesting here.
If you're already happy with the general look of your photos and just want to tweak them a little before sharing them, a simple free photo editor that allows you to resize, crop and apply filters will be ideal. Many of these have social media sharing built in, removing the hassle of uploading your snaps manually later. They also have the benefit of being easier to use.
If you're planning to print your work, you'll be better off considering a more nuanced free photo editor that will give you the fine control you need to make your photos look perfect, even at high resolutions.
A free photo editor that's a worthy rival to premium software
GIMP (the GNU Image Manipulation Program) is the most powerful free photo editor around. It's packed with the kind of image-enhancing tools you'd find in premium software, and more are being added every day.
GIMP’s interface will be instantly familiar if you have ever used Photoshop – especially if you select the single-window mode, which lays out all its toolbars and canvases in an Adobe-style layout.
The photo editing toolkit is breathtaking, and features layers, masks, curves, and levels. You can eliminate flaws easily with the excellent clone stamp and healing tools, create custom brushes, apply perspective changes, and apply changes to isolated areas with smart selection tools.
GIMP is an open source free photo editor, and its community of users and developers have created a huge collection of plugins to extend its utility even further. Many of these come pre-installed, and you can download more from the official glossary. If that's not enough, you can even install Photoshop plugins.
This combination of power and flexibility make GIMP the best free photo editor you can download – whether you're using Windows, macOS or Linux.
Fine manual controls packaged in an accessible interface
More is not, believe it or not, always better. Paint.NET's simplicity is one of its main selling points; it's a quick, easy to operate free photo editor that's ideal for trivial tasks that don't necessarily justify the sheer power of GIMP.
Don't let the name fool you, though. This isn't just a cheap copy of Microsoft's ultra-basic Paint – even if it was originally meant to replace it. It's a proper photo editor, just one that lands on the basic side of the curve.
Paint.NET’s interface will remind you of its namesake, but over the years, they’ve added advanced editing tools like layers, an undo history, a ton of filters, myriad community-created plugins, and a brilliant 3D rotate/zoom function that's handy for recomposing images.
It might not have every feature you can dream of, but if your machine is a little underpowered we can't think of a better free photo editor.
A superb photo editor that takes many of its cues from Photoshop
Photo Pos Pro isn't as well known as Paint.net and GIMP, but it's another top-quality free photo editor that's packed with advanced image-enhancing tools.
This free photo editor's interface is smarter and more accessible than GIMP's array of menus and toolbars, with everything arranged in a logical and consistent way. If it's still too intimidating, there's also an optional 'novice' layout that resembles Fotor's filter-based approach. The choice is yours.
The 'expert' layout offers both layers and layer masks for sophisticated editing, as well as tools for adjusting curves and levels manually. You can still access the one-click filters via the main menu, but the focus is much more on fine editing.
Photo Pos Pro also includes a clone brush for erasing unwanted blemishes, and there's extra support for batch-editing and scripts to help you save time when refining a whole folder of photos.
The free edition of Photo Pos Pro only has one drawback: files can only be saved at a maximum resolution of 1,024 x 2,014 pixels, which might be too small if you're planning to have them printed professionally. If you want to remove this restriction, Photo Pos Pro Premium is available for a license free of £24.50/US$24.90/AU$41.89.
Advanced tools and filters that are easy for beginners to master
PhotoScape might look like a rather simple free photo editor, but take a look at its main menu and you'll find a wealth of features: raw conversion, photo splitting and merging, animated GIF creation, and even a rather odd (but useful) function with which you can print lined, graph or sheet music paper.
The meat, of course, is in the photo editing. PhotoScape's interface is among the most esoteric of all the apps we've looked at here, with tools grouped into pages in odd configurations. It certainly doesn't attempt to ape Photoshop, and includes fewer features.
We'd definitely point this towards the beginner, but that doesn't mean you can't get some solid results. PhotoScape's filters are functional and not at all beginner-like, so it's if good choice if you need to quickly level, sharpen or add mild filtering to pictures in a snap.
One-click photo enhancement tools and advanced manual controls
Fotor is more a photo enhancer than a full-fat manual editing tool. If there's specific area of retouching you need doing with, say, the clone brush or healing tool, you're out of luck. However, if your needs are simple, its stack of high-end filters that really do shine.
There's a foolproof tilt-shift tool, for example, and a raft of vintage and vibrant colour tweaks, all easily accessed through Fotor's clever menu system. You can manually alter your own curves and levels, too, but without the complexity of high-end tools.
Fotor's most brilliant function, and one that's sorely lacking in many free photo editors, is its batch processing tool – feed it a pile of pics and it'll filter the lot of them in one go, perfect if you have a memory card full of holiday snaps and need to cover up the results of a dodgy camera or shaky hand.
