This wikiHow will teach you how to edit a JPG image using a mobile app as well as software on your computer. The best app for photo editing on the go is Google's Snapseed app (both Androids and iPhones can use it), but you might not want to download a new app. In that case, you can use the default photo app on Android, called Google Photos. For iPhones and iPads, you can use the Photos app to make basic edits. As for the computer, you can easily edit photos with photo editing software like GIMP, unless you have a subscription to, or have purchased, Adobe Photoshop. Both GIMP and Photoshop function similarly, so even though this article features more on the free version of GIMP, you can follow the same steps using Photoshop.
Easy Ways to Edit a JPG Photo

- For Android: Open Google Photos, choose the photo, and select Edit at the bottom of the screen.
- For computers: Download a photo editing software (like Adobe Photoshop or GIMP), open the photo in the program, and utilize the various editing tools.

Download an app that edits JPG images. There are plenty of free editing applications available in the Google Play Store or App Store, including Snapseed, PicsArt, VSCO, and Adobe Photoshop Express (which has a limited amount of free features).
-
Open the photo editing app. After you download and install a photo editing app from the App Store or Google Play Store, tap the app on your Home screen or apps menu to open the app.
- For some apps, you may need to permit it to access your phone or tablet's storage before continuing.
-
Open your JPG image. Most of these apps should have a clearly marked + for you to tap and access your camera roll. Once you open your camera roll, tap your JPG image to open it in the photo editor.
-
Edit the JPG image as much as you'd like. Since each app usually has a different setup or slightly different ways to do things, your best bet is to tap around the app and explore the variety of menus it offers. While most of the basic editing tools are free to use, any feature you see with either a lock icon or a dollar sign on it means you'll have to pay to unlock it.
- Cropping a photo is a good way to add more focus on the subject in the image by cutting out some background. The crop tool usually has an icon that resembles two right angles forming a square. To crop an image, select the crop tool and then drag the corners of the image inward so that the light part of the image is centered around the subject in the image. Then tap the icon that confirms the changes you made.
- Using the Snapseed app, you'll find this and many other editing features under the Tools tab.
- Some apps allow you to adjust the saturation, or intensity of color, in a photo. Increasing the saturation of a photo can make the colors pop and make the photo more eye-catching. Too much saturation, though, can make the photo look harsh and almost cartoon-like. You can adjust the saturation to highlight certain areas of an image, so use the sliders available to increase or decrease the saturation levels.
- In photography, exposure refers to the amount of light that falls on a photo. If the photo is too dark, then you might need to increase the exposure. If you want the photo darker, then lower the exposure. Drag the available sliders to increase or decrease the exposure levels.
- Cropping a photo is a good way to add more focus on the subject in the image by cutting out some background. The crop tool usually has an icon that resembles two right angles forming a square. To crop an image, select the crop tool and then drag the corners of the image inward so that the light part of the image is centered around the subject in the image. Then tap the icon that confirms the changes you made.
-
Test the filters and lenses (instead of adjusting everything manually). Many of the photo editing apps available have a variety of filters or lenses to choose from, which essentially do all of the editing for you. Look for tabs or icons at the bottom or top of the photo preview to see what adjustments you can make with the app you are using. Most photo editing apps display filters as thumbnail previews at the bottom of the screen. Tap a thumbnail image to see a preview of how it will affect your image. Look for slider bars or an icon with slider bars that you can use to adjust the intensity of the filter.
- In Snapseed, these are located in the Looks tab.
-
Save your work. Tap the checkmark or Done button to save your work. In Snapseed, you can also tap Export and share your edited JPG image with others.

Get photo editing software. You can do basic edits with programs like MS Paint or Photos (Windows only) and Photos (Mac only), but if you want to make your photos look amazing, you should get a program specifically designed for serious editing. Adobe Photoshop is the industry standard for professional photo editing, but you don't need to pay for an Adobe subscription to do professional photo editing.
- GIMP is a free and open-source photo editing program that has many of the same tools as Photoshop and can be downloaded for free .
-
Open your JPG image in your editing software, like GIMP. If the software doesn't offer an Import or Open button clearly, you can always go to File > Open . This should lead you to your file manager where you can browse for and open your JPG image.
-
Edit it as much as you'd like. Since each software has different menu setups and a different interface, your best bet is to click around the menus to familiarize yourself with that software.
- Cropping a photo is a good way to add more focus on the subject in the image by cutting out some background. The crop tool usually has an icon that resembles two right angles forming a square. To crop an image, select the crop tool and then drag the corners of the image inward so that the light part of the image is centered around the subject in the image. Then click the icon that confirms the changes you made.
- If you want to resize the image instead of cropping it, the resize feature is usually in the Edit menu and will let you adjust the overall size of the image.
- Increasing the saturation of a photo can make the colors pop and make the photo more eye-catching. Too much saturation, however, can make the photo look harsh and almost cartoon-like. You can adjust the saturation to highlight certain areas of an image, so use the sliders available to increase or decrease the saturation levels.
- In photography, exposure refers to the amount of light that falls on a photo. If the photo is too dark, then you might need to increase the exposure. If you want the photo darker, then lower the exposure. Drag the available sliders to increase or decrease the exposure levels.
