Why I built this bulk resizer

I sell pottery online. My product photos were huge – 4000x3000, 5MB each. My store was slow, customers left. I needed a way to resize multiple images at once, keep them sharp, and sometimes target a specific file size (like under 200KB for email). Existing tools either uploaded to shady servers or couldn't do batch. So I built this. It lets me set width/height, lock aspect ratio, and even enter a KB target – it automatically tweaks quality to get close. I use it every week. My neighbour the photographer uses it to resize proofs. Hope it helps you too.

How to resize images – step by step (like I'm showing you)

I’ve done this hundreds of times, so let me walk you through it like you're sitting next to me.

Step 1 – Pick your photos: Click the upload area and select all the images you want to resize. You can mix JPG, PNG, WEBP – the tool handles them.

Step 2 – Set your dimensions: Enter the width and height you need. If you want to keep the original shape, keep "Maintain aspect ratio" checked.

Step 3 – Optional: target file size: Need images under 200KB? Type 200 here. The tool plays with quality until it gets as close as possible.

Step 4 – Hit "Resize Images Now": The tool does everything in your browser. Download individually or grab the whole ZIP.

That's it. No confusing settings. I made this exactly how I wanted it for myself – simple and private.

Who uses bulk resize? (real stories)

Online sellers (like me): Amazon, Etsy, or your own store – they all want specific image sizes. Batch resizing means you list products faster. I often resize image in kb for Amazon's 2000px limit while keeping file size under 1MB.

Photographers: Sending proofs? Resize 50 high-res shots to 1200px width so they load in email, but keep originals safe.

Teachers & students: Make worksheets or upload assignments – change image size free to stay under file limits.

Social media managers: Instagram wants 1080px, Facebook 1200px. Use this photo dimension converter to prep all at once.

What else? Convert format while resizing, target file size for email, resize then compress. I do all of these every week.

Frequently Asked Questions (FAQ)

Can I resize multiple images to exact dimensions?
Yes, select multiple files, set width/height, enable aspect ratio if needed. All images will be resized.

Enter a target size in the "Target KB" field. The tool automatically finds the right quality to hit that size. Works for JPEG/WebP.
