Bulk Image Resizer

Bulk Resize Multiple Images at Once - Free, No Photoshop

Resizing images one at a time is slow. Whether you have 10 product photos that all need to be 800 x 800, a folder of holiday pictures to shrink before emailing, or 50 screenshots to scale down for a document, this bulk image resizer handles them together in a single pass. Drop in as many images as you like, choose how they should be resized, and download every result - individually or as one ZIP file.

Everything runs inside your browser. Your images are never uploaded to a server, which keeps client work and personal photos private and makes the whole process instant even for large batches.

Three Ways to Batch Resize

• By percentage - Scale every image to a fraction of its original size (for example 50%). Best when your images are different sizes and you just want them all smaller.
• Fit within a maximum size - Set a maximum width and height; each image is scaled down to fit inside that box while keeping its proportions. Best for "make everything at most 1200px wide for the web."
• Exact dimensions - Force every image to a specific width and height, such as 800 x 800 for an online store. Keep aspect ratio on to scale without distortion, or off to stretch to the exact size.

How to Bulk Resize Images - Step by Step

1. Add your images - Drag and drop a whole selection, or click and pick multiple files at once.
2. Choose a resize mode - Percentage, fit-within, or exact dimensions, depending on what you need.
3. Pick output format and quality - Keep the original format or convert all images to JPG, PNG, or WEBP. Set quality for JPG and WEBP.
4. Click Resize All - Every image is resized in your browser. Each tile shows the new size.
5. Download - Save images individually, or click Download All for a single ZIP of the whole batch.

Batch Resizing Without Photoshop

In Photoshop, batch resizing means recording an Action or writing an Image Processor script, then running it across a folder. That works, but it requires a paid license and a desktop install. If you just need to resize a set of images quickly, an online bulk resizer is faster: there is nothing to set up, it works on any device including Chromebooks and phones, and the result downloads straight to your computer. For one-off jobs and most everyday resizing, this is the simpler path.

Common Bulk Resize Sizes

Use case	Suggested setting
Online store product images	Exact 800 x 800 or 1000 x 1000
Web page images (faster loading)	Fit within 1200 x 1200
Email attachments	Fit within 1024 x 1024 or 50%
Blog featured images	Exact 1200 x 628
Thumbnails	Fit within 300 x 300
Just make everything smaller	By percentage, 50%

Tips for the Best Results

• Start from originals - Resize from the highest resolution copies you have; never resize an already-resized file repeatedly.
• Resize before compressing - Reducing dimensions cuts file size more than compression alone. Run the batch through the bulk compressor afterwards for the smallest files.
• Use WEBP for the web - Converting to WEBP while resizing gives the smallest files at high quality.
• Keep aspect ratio for photos - Only force exact dimensions when you specifically need a fixed size, such as a square product grid.
