Bulk Image Resizer

Modern phone cameras produce images several thousand pixels wide, which is far more than any web page needs. Uploading them untouched forces every visitor to download megabytes of detail their screen will never show, and on a mobile connection that is the difference between a page that loads and one that is abandoned.

Resizing one image is easy; resizing eighty product photographs before a store launch is a chore that eats an afternoon. This tool processes a whole batch at once, scaling every file to the width you specify while preserving each image's aspect ratio, then packaging the results in a single ZIP download.

The processing runs entirely in your browser using the canvas API, so nothing is uploaded to a server. That matters for client photography, unreleased product shots and personal images. Keep your originals somewhere safe: resizing discards pixels permanently, and you may need the full resolution version later for print or for a larger layout.

How to use the Bulk Image Resizer

1. Select all the images you want to resize in one go.
2. Enter the target width in pixels; height is calculated to preserve proportions.
3. Start processing and wait while each image is scaled.
4. Download the ZIP archive containing the resized files.
5. Check a couple of the results at full size before publishing them.

Examples

• A shop owner resizes eighty product photographs to a consistent 1200 pixel width before uploading a catalogue.
• A blogger shrinks a folder of camera images so an article loads quickly on mobile data.
• A club secretary prepares an event gallery from members' phone photos at a uniform size.

Frequently asked questions

Are my images uploaded anywhere?

No. Everything happens locally in your browser, and the ZIP is assembled on your device.

What width should I choose?

Around 1,200 to 1,600 pixels suits most full-width web images. Thumbnails and gallery tiles can be much smaller.

Can I enlarge small images?

You can set a larger width, but scaling up cannot invent detail and generally looks soft. Start from the largest original you have.

How many files can I process at once?

Dozens are fine. Very large batches of high resolution images may use a lot of memory, so split them if your browser struggles.
