Resize Hundreds of Images in Seconds
Stop resizing images one by one. Vizua's bulk image resizer lets you drop up to 100 photos at once, choose your target format and quality, and download everything as a ZIP. Whether you are preparing product photos for an e-commerce store, resizing event pictures for a gallery, or batch-processing screenshots for documentation — this tool handles it all instantly.
Common Bulk Resize Scenarios
- E-commerce product photos — resize hundreds of product images to a consistent size for your online store. Uniform dimensions make listings look professional.
- Blog and website images — batch resize photos to web-friendly dimensions (e.g. 1200px wide) and WebP format for faster page loads.
- Social media content — prepare multiple images at the right dimensions for Instagram, Facebook, or Twitter in one go.
- Email attachments — reduce image dimensions and file sizes before attaching to emails. What was 50 MB of photos becomes 5 MB.
Convert and Resize in One Step
The bulk resizer also converts formats. Upload PNG files and output optimized WebP. Drop BMP files and get compressed JPGs. Format conversion happens automatically alongside the resize, saving you an extra step.
Everything Stays on Your Device
No images are uploaded to any server. Vizua uses your browser's built-in processing power to handle the entire batch locally. Your photos remain 100% private — nothing leaves your computer.
Frequently Asked Questions
How many images can I resize at once?
Up to 100 images per batch. Drop them all at once and Vizua processes each one. Download individually or grab everything as a single ZIP file.
Can I set specific dimensions for the bulk resize?
Yes — choose your target format and quality. The tool resizes all images to your specifications while maintaining the original aspect ratio to prevent distortion.
What formats does the bulk resizer support?
Input: JPG, PNG, WebP, GIF, and BMP. Output: JPG, PNG, or WebP. You can even convert formats while resizing — for example, resize and convert PNG to WebP in one step.
Is bulk resizing slower than single image resize?
Vizua processes images in parallel using your browser. A batch of 20 images typically finishes in seconds. Larger batches (50-100 images) may take 10-30 seconds depending on your device.
Are the resized images compressed?
For JPG and WebP output, you control the quality slider (1-100%). Lower quality means smaller files. PNG output is always lossless. This lets you balance file size vs. visual quality for your specific needs.
