Reposition: put your image on a custom-sized canvas

Puts your image on a new canvas at the exact size you want — perfect for hitting size requirements on print-on-demand sites and Etsy.

The Reposition tool takes whatever the previous step gave it and puts it on a fresh, custom-sized canvas. It lets you set the exact width, height, and print quality you want. This is the step that makes your output ready to upload.

Why this step matters

Different websites want different image sizes.

Amazon Merch shirts want 4500 by 5400 pixels
Etsy listing images want at least 2000 by 2000 pixels
Printful and Printify want different sizes depending on the product
Upload the wrong size and the site will either reject the image or squish it

Reposition makes sure every image in your batch comes out at the exact size you want, no matter what the original looked like.

The six settings

When you add Reposition to your pipeline, you'll see these controls:

Setting	What it does
DPI	A number the printer uses to tell how finely to print. 72 for images going on the web or social media. 300 for images that will actually be printed on something.
Unit	Whether your width and height are in pixels, inches, or centimeters. Most people use pixels.
Canvas Width	How wide you want the final image to be.
Canvas Height	How tall you want the final image to be.
H-Align	Where your image sits horizontally on the canvas: L (left), C (center), or R (right).
V-Align	Where your image sits vertically: T (top), C (center), or B (bottom).
Padding	How much empty space to leave between your image and the edge of the canvas, in pixels.

The new canvas is always transparent (see-through). If you want a solid color behind your image, add a Frames step earlier in the pipeline.

DPI in plain English

DPI is a number that tells a printer how sharp to make the final print. It does not change the size of your image.

72 DPI is fine for anything going on the web or social media
300 DPI is what print-on-demand sites want because it prints sharper
A 4500 by 5400 image at 72 DPI has the exact same pixels as a 4500 by 5400 image at 300 DPI — the printer just treats them differently

Use 300 for anything that will be printed on something physical. Use 72 for anything going online.

Common sizes people use

Type these into Canvas Width and Canvas Height. Make sure Unit is set to px (pixels).

Where you're uploading to	Width × Height	DPI
Amazon Merch (shirts, hoodies, sweatshirts)	4500 × 5400	300
Amazon Merch PopSockets	1000 × 1000	300
Etsy listing main image	2000 × 2000 (minimum)	72 or 300
Shopify product page hero	2048 × 2048	72
Shopify catalog grid thumbnail	1200 × 1200	72
Website hero image	2400 × 1200	72
Social media post	2048 × 2048	72

For Printful, Printify, Redbubble, or TeePublic — go check the product's template page on their website. Every product has its own recommended size. Copy the numbers into Canvas Width and Canvas Height.

Tips

Put Reposition near the end of your pipeline. Remove the background first (with Color Removal). Cut off the empty edges (with Trim). Then put the clean result on your target canvas with Reposition. Doing this in a different order leaves your image small and off-center on a big empty canvas.
Save the whole pipeline as a preset. Once you've set up "Merch 4500x5400" or "Etsy 2000 square," click Save Current Preset. Next time, one click loads the whole pipeline — no retyping dimensions.
Use Padding if the site crops your image. Some print-on-demand sites cut a few pixels off each edge during upload. A padding of 50 to 100 pixels keeps your design safely inside.
Center is almost always right. H-Align: C and V-Align: C work for most product images and designs.

Things Reposition doesn't do

It doesn't make your image bigger or sharper. Reposition just places your image on a bigger canvas — it leaves the image itself alone. If you need the image to fill the whole canvas, use the Resize tool earlier in your pipeline.
It doesn't give you a colored background. The canvas is always transparent. If you need a color or pattern behind your image, use the Frames tool earlier in the pipeline.
It has no built-in platform presets. You have to type the numbers in yourself. But you can save your own pipeline as a preset so you never have to type them twice.
