Quick answer

To resize many product photos at once, drop a ZIP or up to 500 photos into the ListingFix bulk image resizer and choose a marketplace or custom size. It pads or crops each photo, resizes it, fits the file limit, tests the result, and returns a new ZIP. Nothing is uploaded.

What this tool does

ZIP in, ZIP out
Opens a standard ZIP or loose JPG, PNG and WebP files in your browser, then returns one new ZIP.
Marketplace presets
Applies the shape, pixel size and file limit saved for your marketplace, with its source or a seller guidance note.
Custom size
Takes your own width, height and KB limit when your marketplace or sales channel is not in the list.
Pad or crop
Adds white space to keep the whole photo, or centre crops it when the marketplace sets a shape.
Report for every photo
Tests each finished file, marks it pass, check or fail, and names problems such as background or resolution.
Folders kept
Keeps your folder structure and base file names, replacing spaces and unusual symbols in names with hyphens.

How to use it

1Drop a ZIP or select several photos.
2Choose a marketplace or enter a custom size, then pad or crop.
3Press Resize, read the report and download the new ZIP.

A new catalogue can mean hundreds of photos, each needing the same shape, size and file limit. Doing that one by one in a photo editor eats a whole afternoon. Here you drop one ZIP, choose the marketplace, and every photo goes through the same steps.

All the work happens on your own device. The ZIP is opened in the browser tab, the photos are never sent anywhere, and closing the tab clears them. That also means speed depends on your device, and a phone can take a while on a large batch.

What happens to each photo

Each photo is padded on white or cropped to the shape you chose, resized to the recommended pixels and saved as a JPG, searching for the best quality that fits under the file limit. Then it is tested against the same rules as the image checker, so the report describes the finished file.

A resize cannot repaint a background. If a photo was shot on grey or cream, it can fail the white background test after resizing. Those photos are marked in the report so you can treat them with the background remover and run them again.

Folders and file names stay the same

The new ZIP keeps your folder structure. File names stay the same except that spaces and symbols become hyphens, so my photo.jpg becomes my-photo.jpg, and the extension can change. If your catalogue sheet refers to photos by name, use simple names to keep those references working. Files that could not be read are listed as skipped and left out.

Questions sellers ask

How many photos can I resize at once?

Up to 500 in one batch. The practical limit is your device memory, because every finished photo is held in the browser until you download the ZIP. On a phone or an older laptop, splitting a very large catalogue into smaller ZIPs is more reliable.

Are my photos uploaded to a server?

No. The ZIP is opened and processed by code running in your browser tab, and nothing is sent anywhere. You can check by turning off your internet after the page loads, then running a batch. It should still finish normally.

Should I pad or crop?

Pad keeps the entire photo and adds white space, which is the safer choice when products sit near the edges. Crop fills the frame and looks larger in search results, but cuts the sides. It works best when every product is centred with room around it.

Why did a photo still fail?

The usual reason is the background. Resizing fixes shape, pixel size, file limit and format, but it does not change what the camera captured. A very detailed photo may also be unable to reach a tight file limit at acceptable quality. The report line names the rule that failed.

What about password protected ZIP files?

They cannot be opened here. Extract the photos first, then either build a normal ZIP or select the image files directly. RAR and 7z archives need the same treatment, since only standard ZIP files are read by this tool.

Is there a free tool to resize product photos in bulk?

Yes. This bulk image resizer is free, runs in your browser and takes up to 500 photos in one batch. You drop a ZIP or select several photos, choose a marketplace or custom size, and download a new ZIP with a report line for each photo.

What size will my photos be for Daraz?

The Daraz preset makes a square 1024 x 1024 JPG under 1 MB. Those numbers come from seller guidance, because we could not confirm them on a Daraz page. Check the current figure in your seller center, or enter a custom size if it shows something different.

Can I bulk resize photos on my phone?

Yes. Open this page in your phone browser, then select several photos or choose a ZIP file. All the work happens on the phone, so a large batch can take a while. Splitting a big catalogue into smaller ZIPs is more reliable on a phone.

Will resizing make a small photo blurry?

It can. A photo smaller than the target size is enlarged to reach it, and enlarging cannot add detail that the camera never captured. Check small originals closely in the finished ZIP, and photograph those products again at a higher resolution if they look soft.

Why did crop not change the shape of my photos?

Crop only works when the marketplace sets a required shape. Presets such as Amazon, eBay and Etsy have no fixed ratio here, so each photo keeps its own shape and is simply resized. Pick a custom width and height if you want every photo in one shape.
