How to Batch Resize Photos in Photoshop in Only 2 Minutes

How to Batch Resize Photos in Photoshop

Modern cameras produce enormous files, and most of the time nobody needs them at full size. A client wants proofs. Something is going to social media. A gallery needs 800-pixel-wide previews. Doing that one image at a time for a wedding or an event is an afternoon of work for a task the computer should be handling by itself.

Photoshop can process an entire folder unattended. You record yourself resizing and saving a single image once, then point that recording at a folder and walk away. It is one of the more useful features in the application and one of the least known.

Record an Action Once

An action is a recording of the steps you take. Everything from the moment you press record is captured and can be replayed on any other file.

1. Open one image from the set

   Any of them. This is the file you will demonstrate the process on.

2. Open Window > Actions

3. Create a new folder in the Actions panel

   Name it something you will recognize later — Resize works. This is the “set” the batch dialog will ask for.

4. Click the new action icon and name the action

   Name it for what it does, such as 800px. Being specific matters once you have several of these.

5. Press Record

Everything You Do Now Is Being Captured

From this point every step is written into the action, so work deliberately. Stray adjustments get recorded too and will be replayed on every file in the folder.

Resize and Save the One Image

6. Go to Image > Image Size and set the width

   800 pixels for this example. The action stores the instruction, not the result, so it will apply the same width to every file it processes.

7. Go to File > Save As

   The location genuinely does not matter — the desktop is fine. It is being overridden later, which is the part most people miss.

8. Choose JPEG and set the quality

   Around 10 gives a good balance for previews and client proofs.

9. Press Stop in the Actions panel

Point the Action at a Folder

10. Go to File > Automate > Batch

11. Choose your Set and Action

    The folder and action you just created — Resize and 800px.

12. Set Source to Folder and choose the images

    You can also run it on files already open, but a folder is the usual case.

13. Tick the suppress options

    Suppress File Open Options Dialogs, and Suppress Color Profile Warnings.

Why the Suppress Options Matter

Without them, Photoshop stops and asks a question every time it hits a file that raises one — which defeats the entire purpose of leaving it running. Ticking both is what makes the batch genuinely unattended.

Set the Destination and File Naming

14. Set Destination to Folder and choose where the results go

    Create a new folder for them — something like 800 px — so the resized copies never mix with the originals.

15. Build the file name

    Set the first field to Document Name, then add an underscore and a label such as 800. Set the remaining fields to None, and make sure the extension is included.

16. Tick Override Action Save As Commands

17. Press OK

Override Action Save As Commands Is the One That Matters

Your action contains a Save As pointing at wherever you saved that first test file. Left alone, the batch would obediently write every image to that same place with that same name. Ticking this box tells Photoshop to keep the file type and quality from the recording but take the destination and naming from the batch dialog instead. It is the reason the location you chose while recording was irrelevant — and forgetting it is the single most common way this goes wrong.

What Trips People Up

Leaving Override Action Save As Commands unticked is the big one, and the symptom is confusing: the batch appears to run correctly but the output folder is empty or holds a single file. After that it is forgetting the suppress options and returning to find Photoshop waiting on a dialog it hit two minutes in. And recording stray steps — a crop, an adjustment, a stray brush stroke — which then get faithfully applied to every image in the folder.

Why Recording Beats Repeating

The value here is not the resize itself — resizing a single image is trivial. It is that the work of deciding how to resize happens exactly once and is then applied identically to every file. Consistency is the real product: every proof in the set comes out at the same dimensions, the same quality and the same naming convention, which is precisely what falls apart when the same job is done by hand across two hundred images.

Build the Ones You Use Repeatedly

Once the pattern is clear, the same approach covers anything you find yourself doing to whole shoots — a different pixel width for a different client, a watermark, a particular export quality. Each one is a couple of minutes to record and saves that time back on the very first folder you run it against. Start with the size you send out most often and build from there.
