Choosing a free photo-editing app
Free apps change features, prices and restrictions regularly. Rather than treating one current list as permanent, choose an editor that performs the jobs you actually need and exports your photographs at useful quality.
What a beginner really needs
Look for crop and straighten, exposure, highlights and shadows, white balance or colour controls, and a way to compare the edit with the original. RAW support matters only if you intend to edit RAW files.
Check the catch before committing
Some free editors limit export size, add watermarks, lock useful tools behind subscriptions or store work only in their own cloud. Check those limits before building a workflow around the app.
Keep your original
Whatever you choose, keep the untouched original photograph. An editing app should be a tool, not the only place where your photographs exist.
