How To Rebase Your Git Branch To Fix Merge Conflicts

Rebasing in Git sounds intimidating, especially when merge conflicts pop up. But once you understand what’s happening under the hood, it becomes a straightforward way to keep your work clean and up to date.

This guide walks through what rebasing is, how it helps with merge conflicts, and how to actually do it step by step—without assuming you’re already a Git expert.

What does “rebasing a branch” actually mean?

In Git, a branch is just a pointer to a series of commits (a line of history).

When you rebase your branch, you’re telling Git:

“Take my work (my commits) and replay it on top of some other branch, as if I had started there in the first place.”

Most commonly, that “other branch” is:

main or master
a shared feature or release branch

So if you have:

main with commits A - B - C
feature with commits A - B - X - Y

…then rebasing feature onto main (after main moves ahead) will:

Take X and Y
Replay them as new commits on top of the latest main (e.g., after C, D, E)

The end result is a clean, linear history:

main: A - B - C - D - E
feature (rebased): A - B - C - D - E - X' - Y'

Those ' marks mean: similar content to X and Y, but they are technically new commits.

Why rebasing can help with merge conflicts

Merge conflicts happen when:

Git tries to combine changes from two branches
The same part of a file was changed in both places
Git can’t automatically decide which version is correct

Rebasing helps because you:

Bring your branch up to date with the latest main (or another base branch)
Resolve conflicts once, as your commits are replayed
End up with a branch that’s easier to merge later, often with fewer conflicts at that time

You’re essentially dealing with conflicts earlier and in smaller chunks, commit by commit, instead of in one big, messy merge.

The basic rebase workflow to resolve merge conflicts

Here’s the standard sequence when rebasing a feature branch onto main.

1. Make sure your local `main` is up to date

git checkout main git pull origin main

This:

Switches you to main
Updates it with the latest changes from the remote

2. Switch to your feature branch

git checkout my-feature-branch

Now you’re on the branch whose history you want to replay.

3. Start the rebase

git rebase main

This tells Git:

“Take my commits from my-feature-branch that aren’t in main yet”
“Replay them on top of the current main”

If there are no conflicts, Git will:

Reapply your commits
Finish the rebase automatically

If there are conflicts, Git will:

Pause at the problematic commit
Ask you to fix the conflicts manually

4. Handle conflicts when they appear

When conflicts occur, Git will show messages in the terminal such as:

CONFLICT (content): Merge conflict in path/to/file.ext
Stopped at <commit-hash>... <commit message>

Your files will contain conflict markers like:

<<<<<<< HEAD code from main (or the base branch) ======= code from your commit >>>>>>> my-feature-branch

To resolve:

Open the file in your editor or IDE
Decide what the final correct code should be:
- Keep one side
- Combine parts from both
- Rewrite the section entirely
Remove the conflict markers (<<<<<<<, =======, >>>>>>>)
Save the file

Repeat this for each conflicted file.

5. Mark conflicts as resolved and continue the rebase

Once you’ve fixed the conflicts in all affected files:

git add path/to/file1.ext git add path/to/file2.ext # or just: git add .

Then tell Git to continue the rebase:

git rebase --continue

Git will:

Try to apply the next commit in your branch
Either succeed and move on
Or stop again if another conflict appears

Repeat the resolve → add → rebase --continue cycle until the rebase finishes.

6. If you make a mistake, you can abort

If the rebase is getting messy or you realize you don’t want to continue:

git rebase --abort

This:

Stops the rebase
Puts your branch back exactly how it was before you started rebasing

No history is changed, and you can regroup.

7. After rebasing, update the remote branch (with care)

Because rebase rewrites history, your rebased branch’s commits are now different from what’s on the remote. To push:

git push --force-with-lease origin my-feature-branch

--force-with-lease is safer than --force because it:

Refuses to overwrite the remote if it has new commits you don’t have locally
Helps avoid accidentally deleting teammates’ work

This step is where collaboration details start to matter a lot.

Key variables that affect how you should rebase

Rebasing isn’t one-size-fits-all. How you use it—and whether you use it at all—depends on several factors.

1. Repository type and team workflow

Solo project
You have more freedom to rebase and rewrite history often.
Small team
Some teams prefer a clean, linear history and use rebase regularly.
Large or highly regulated team
Some organizations avoid rebasing shared branches to preserve an exact audit trail of every commit and merge.

Team policies may dictate:

Whether you can rebase shared branches
When to use git merge vs git rebase
How to handle force pushes

2. Branch type

Rebasing makes more or less sense depending on the branch:

Feature branches (short-lived)
Commonly rebased onto main to stay current and reduce merge conflicts later.
Long-lived branches (e.g., develop, release)
Some teams prefer merging instead of rebasing to avoid rewriting widely used history.
Protected branches (main, master)
Usually not rebased in shared repos—these are often merge-only and protected from force pushes.

3. Collaboration level

You’re the only one using the branch
Rebasing and force pushing are low risk (as long as you know what you’re doing).
Multiple people share the branch
Rebasing becomes more complicated:
- Others may have based their work on “old” commits you’re rewriting
- Force pushes can disrupt their history and cause confusion

Some teams have a strict rule: “Never rebase public/shared branches, only local/personal branches.”

4. Your Git skill and comfort level

Your comfort with:

Reading and resolving conflicts
Understanding commit history
Recovering from mistakes (e.g., git reflog, git rebase --abort)

…will affect:

How often you’re willing to rebase
Whether you prefer simple merges instead
How granular you make your commits before rebasing

5. Tooling: CLI vs GUI

Your experience changes depending on tools:

Command line only
You’ll be reading conflict markers and messages in the terminal.
GUI tools / IDE integration
You may get:
- Side-by-side diff views
- Clickable conflict resolution
- Visual commit graphs

These tools don’t change how Git works, but they can make the process more approachable.

Different ways rebasing plays out for different users

Depending on your situation, rebasing to fix merge conflicts can look very different.

Scenario 1: Solo developer on a personal project

Typical pattern:

You work on my-feature-branch for a while.
main gets ahead (maybe from another machine or future you).
You run git rebase main, fix a few conflicts, and push with --force-with-lease.

In this world:

There’s no risk of breaking teammates’ history.
You can aggressively rewrite history to keep things tidy.
Rebasing is mostly a convenience and learning exercise.

Scenario 2: Small team with agreed “rebase-friendly” workflow

Common setup:

Each developer creates a feature branch from main.
Before opening or updating a pull request, they:
- git fetch
- git rebase origin/main
- Resolve conflicts
- Force push to update their feature branch

Benefits:

Pull requests are easier to review (clean history, fewer noisy merge commits).
Conflicts show up earlier and closer to the relevant commits.
Everyone understands that force pushes are expected on personal feature branches.

But this works only if:

The team is aligned on the rules.
People avoid rebasing branches that others already depend on.

Scenario 3: Larger or conservative team with merge-only policy

In some teams:

Rebasing a shared branch is discouraged or even forbidden.
Everyone uses git merge instead of git rebase for shared history.

In this world, you might:

Only rebase local, not-yet-pushed work
Or avoid rebasing entirely and resolve conflicts during merges instead

Merge conflicts still happen—but they’re handled differently:

During git merge main instead of git rebase main
Conflicts may all appear at once, at merge time, rather than commit-by-commit

Scenario 4: Advanced cleanup with interactive rebase

Beyond basic git rebase main, some people use:

git rebase -i main

(interactive rebase) to:

Reorder commits
Squash multiple small commits into one
Edit commit messages
Drop unwanted commits

Conflicts can still occur, but you get:

A chance to tidy your commit history while resolving conflicts
A more curated, readable history

This is powerful, but best suited for users already comfortable with normal rebase and conflict resolution.

Where your own situation becomes the deciding factor

The mechanics of rebasing to resolve merge conflicts are relatively consistent:

Update the base branch (main, etc.)
git rebase base-branch
Fix conflicts in files
git add the fixed files
git rebase --continue until done
Push, often with --force-with-lease if history changed

What varies a lot from person to person is:

Whether you should rebase at all on shared branches
How often you update your branch with the latest main
Whether your team prefers merges, rebases, or a mix of both
How comfortable you are with resolving conflicts and recovering from mistakes
What tools (terminal, IDE, GUI) you’re using to visualize and manage history

Understanding those moving parts is what turns rebasing from something scary into just another tool in your Git toolbox. The right way to use it depends heavily on your repo, your team norms, and your own workflow.
