Edit means to change, fix, or improve something you have already created
When you edit something, you are opening it again to make changes. You might fix a typo in a document, crop a photo, rewrite a sentence, delete a line, or adjust the volume on a video. Editing is not creating something new — it is changing something that already exists.
You edit files on your computer, phone, or tablet all the time without thinking about it. When you correct a text message before sending it, you are editing. When you change the name of a photo or delete a paragraph from an email, you are editing. The word shows up in menus and buttons because programs need to let you know that clicking will let you make changes to what is already there.
Key Takeaways
- Edit means to open something you created and change it, rather than create something new from scratch.
- Most programs show an Edit button or menu option that lets you change text, images, videos, or other content you have already made.
- When you edit a file, you are usually working on the original unless you save it with a different name.
- Different programs use different tools for editing, but the basic idea is the same across all of them.
Where you see the word "edit" on your screen
The word Edit usually appears in a menu at the top of a program, or as a button or pencil icon somewhere on the screen. On your computer, look for "Edit" in the menu bar next to "File" and "View" — this is where you find options to undo changes, cut and paste text, or find and replace words. On your phone or tablet, you might see a pencil icon or an "Edit" button in the corner of the screen.
Right-clicking on a file or text often shows an "Edit" option in a small menu that pops up. This is a shortcut to open the file in a way that lets you change it. Some programs also show "Edit" as a button you tap or click to switch from viewing mode (where you can only look) to editing mode (where you can make changes).
The difference between viewing and editing
Many programs let you view a file without being able to change it. This is called read-only mode. You might open a document to read it but not be allowed to edit it because someone else owns it or locked it. When you want to make changes, you need to switch to edit mode or open the file in a program that lets you edit.
Some files are set to read-only on purpose — for example, a teacher might share a document that students can read but not change. If you need to edit a read-only file, you usually have to ask the owner for permission, or save a copy of it to your own account first. On your phone, some apps show a "View" button for looking at something and an "Edit" button for changing it.
How to edit different types of files
Text files and documents open in programs like Microsoft Word, Google Docs, or Notepad, where you can click anywhere and start typing to make changes. Photos and images open in programs like Photos, Preview, or Photoshop, where you crop, rotate, adjust colors, or add text. Videos open in video editors where you can trim, rearrange clips, or add music.
The program you use depends on what kind of file it is. A photo file (like .jpg or .png) will not open in a word processor. A video file (like .mp4) will not open in a text editor. Your device usually knows which program to use when you double-click a file, but you can also right-click and choose "Open with" to pick a different program if you want.
Saving your changes after you edit
When you make changes to a file, those changes stay in your computer's memory until you save the file. Saving writes your changes to the hard drive so they do not disappear if you close the program or turn off your device. Most programs remind you to save if you try to close without saving — you will see a message asking "Do you want to save changes?"
You can save over the original file (which replaces it with your new version) or save it with a different name (which keeps the original and creates a new file with your changes). Use "Save As" if you want to keep both versions. If you make a mistake while editing, you can usually undo your changes by pressing Ctrl+Z on Windows or Command+Z on Mac, or by clicking the undo arrow in the program.
Editing on your phone or tablet
Phones and tablets work the same way as computers, but the buttons and menus look different. When you open a photo in the Photos app and tap the pencil icon, you are entering edit mode. You can then crop, rotate, adjust brightness, or add filters. When you are done, you tap "Save" or "Done" to keep your changes.
For documents and notes, you might see an "Edit" button at the top of the screen. Tap it to switch from reading mode to editing mode, where you can type and make changes. Some apps on phones and tablets do not let you edit at all — they are view-only. If you need to edit something on your phone, you may need to use a different app or open it on your computer instead.
Common editing tasks and what they mean
When you edit, you might see terms like "cut," "copy," "paste," "find and replace," or "undo." Cut removes something and saves it so you can paste it elsewhere. Copy saves a version without removing the original. Paste puts what you cut or copied into a new spot. Find and replace searches for a word or phrase and changes it to something else throughout the whole document.
Undo takes back your last change. Redo puts it back if you change your mind. These tools are in the Edit menu on most programs, or you can use keyboard shortcuts: Ctrl+X to cut, Ctrl+C to copy, Ctrl+V to paste, Ctrl+Z to undo, and Ctrl+Y to redo on Windows. On Mac, use Command instead of Ctrl.
Frequently Asked Questions
What happens if I edit a file someone shared with me?
If you have permission to edit, your changes save to your version. If the file is shared in a program like Google Docs, everyone sees your changes in real time. If it is read-only, you cannot make changes unless you ask the owner to give you editing permission or you save a copy to your own account.
Can I edit a file after I close it?
Yes. You can open any file again and edit it as many times as you want. Each time you save, your new changes replace the old version (unless you save it with a different name). Files do not disappear after you close them — they stay on your device until you delete them.
What is the difference between edit and delete?
Edit means to change something that exists. Delete means to remove it completely. When you edit, the file stays on your device with new changes. When you delete, the file is gone (though you may be able to recover it from the trash or recycle bin for a while).
Why does some software say I cannot edit a file?
A file might be read-only because the owner locked it, because you do not have permission, or because the program you are using does not support editing that type of file. Check if you need permission from the owner, or try opening the file in a different program that is designed for editing that kind of content.
Do I lose the original if I edit a file?
No, unless you save over it. When you edit and click Save, you replace the original with your new version. To keep both, use Save As and give it a different name. This creates a new file with your changes while leaving the original untouched.
