How to Batch Resize Images Online Free — Resize Multiple Photos at Once
What is batch image resizing?
Batch resizing means applying the same dimensions — or the same percentage scale — to multiple images at once, instead of editing each file individually. It is the fastest way to prepare a set of product photos for an online store, standardize social media images, or compress a folder of photos before uploading them to a website.
When to use batch resize instead of single resize
Use batch resize when:
- You have 5 or more images that all need the same output dimensions - You are preparing a product catalog for Etsy, Amazon, or Shopify - You are resizing screenshots or assets for a presentation or report - You want to standardize a set of profile photos or team headshots
For a single image or an image that needs precise cropping control, the standard resize tool gives you more options.

Set your batch resize target to one of these standard sizes and all images will be ready to upload in one step.
Batch resize vs batch compress — which do you need?
Resize changes the pixel dimensions of an image. Compress reduces the file size without changing dimensions. You often need both:
1. Batch resize to the correct pixel dimensions for your platform. 2. Batch compress to bring file sizes under platform upload limits (usually 1–5 MB).
Designora has separate free tools for both. Start with resize, then compress if the file sizes are still too large after resizing.
