Resize images in your browser
Set the pixel size you need, choose whether to pad or crop, and download. Nothing is uploaded and there is no sign up.
Your files stay in your browser. Nothing is sent to a server.

What the resizer does
Exact pixel sizes
Type the width and height you need, or pick a preset. Fill in one side only and the other is worked out for you, so the shape stays right.
Pad or crop, your choice
Fit the photo inside the frame and add space around it, or fill the frame and cut the edges. White is the default space colour, because product listings usually want white.
A batch at once
Drop up to 20 files. Each one is resized with the same settings and keeps its original file name.
Nothing leaves your computer
The resizing happens inside this page. Your photos are never sent to us, so there is nothing to delete afterwards.
How to resize an image
Choose your images
Click the box or drop files onto it. JPG, PNG, WebP and most other image formats work.
Set the size
Pick a preset or type a width and a height. Leave one field empty to keep the original shape.
Choose pad or crop
Fit inside adds space around the photo. Fill the frame cuts the edges instead. You choose the colour of any space that is added.
Download
Each row shows the new size in pixels and the new file size. Download one file, or all of them together.
Which fit setting to choose
| What you need | Setting to use |
|---|---|
| The whole product must stay visible | Fit inside and add space |
| The image must be square and fill the frame | Fill the frame and crop |
| You want a white border around the product | Fit inside, with white as the space colour |
| The photo is already the right shape | Fit inside. No space is added when the shapes match. |
How do you resize an image without losing quality?
Making an image smaller keeps it sharp, because the detail is being averaged rather than invented. Making it larger is where quality drops, since the new pixels have to be guessed from the ones already there. So reduce a photo freely, and try not to enlarge it by more than about a third. When a small photo has to work at a large size, an AI image upscaler rebuilds the detail instead of stretching it.
What size should a product photo be?
There is no single answer, because every store platform and marketplace publishes its own limits and those limits change. Three rules hold everywhere. Use a square shape unless you have a reason not to. Make the longest side big enough that a shopper can zoom in without the photo going soft. Keep the file under whatever size cap the platform states. Check the current requirement in your own seller documentation before a bulk upload, then resize once for the strictest one.
Why does resizing in the browser matter?
This tool does the work on your own machine, so your photos are never uploaded. For a product you have not launched yet, that is the difference between a private file and a file that sits on a server you do not control. It is also quicker on a batch, because nothing waits for a network round trip.
What comes after resizing?
Resizing changes the frame, not the photo inside it. If the photo itself is the problem, the fix is a clean cut-out, a studio background or a shot on a model. That is what the DesignerBox studios do from the same file: upload one product photo and generate angles, scenes, ads and product video from it.
Image resizer questions
Is the image resizer free?
Yes. It is free to use with no account and no watermark. The resizing runs in your own browser, so there is no cost for us to pass on.
Are my photos uploaded anywhere?
No. The file is read by this page and resized on your own device. It is never sent to DesignerBox or to any other server.
How many images can I resize at once?
Up to 20 files in one go, each up to 40 MB. They all use the same settings, and you can download them one by one or all together.
Which file formats work?
JPG, PNG, WebP and any other image format your browser can open. You can save the result as JPG, PNG or WebP.
Will resizing make my image blurry?
Making an image smaller keeps it sharp. Making it much larger will look soft, because the added pixels are estimated from the original ones. For a large jump in size, use an AI upscaler instead of a resizer.
Does it keep the aspect ratio?
Yes, when you fill in only the width or only the height. If you set both, choose Fit inside to keep the shape and add space, or Fill the frame to cut the edges.
The size is right. Now make it a better photo.
Upload one product shot and DesignerBox generates angles, studio scenes, on-model images, ads and video from it.
