Overview

Batch Image Convert is a fast, browser-based utility that lets you upload up to 50 images and convert them simultaneously to formats like JPG, PNG, WebP, AVIF, TIFF, or GIF. You can customize output quality, resize dimensions while maintaining aspect ratio, choose background colors for transparency, and preserve metadata.

When to Use

  • •When you need to optimize multiple high-resolution photos for web use by converting them to modern formats like WebP or AVIF.
  • •When you need to resize a batch of images to specific dimensions for a website gallery or social media platform.
  • •When you need to convert transparent PNGs or GIFs to JPGs with a solid white or black background.

How It Works

  • •Upload up to 50 image files in formats like JPG, PNG, WebP, AVIF, TIFF, or GIF.
  • •Choose your target output format, adjust the quality slider, and optionally set custom width or height dimensions.
  • •Configure advanced options such as maintaining aspect ratio, choosing a background color, and keeping original file names or metadata.
  • •Click convert to process the files and download the converted images in a single ZIP archive.

1. Convert and Compress Images for Web Performance

Web Developer
Background
A developer needs to optimize 30 high-resolution JPG screenshots for a blog post to improve page load times.
Problem
The original JPG files are too large and need to be converted to WebP at 80% quality to save bandwidth.
How to Use
Upload the 30 JPG files, select 'WebP' as the output format, set the quality slider to 80, and keep the original file names.
Example Config
Output Format: WebP, Quality: 80, Keep Original Names: True
Outcome
A ZIP file containing 30 optimized WebP images with significantly reduced file sizes.

2. Resize Product Images for E-commerce Store

Store Owner
Background
An online store owner has 15 product photos of varying sizes that need to fit a standard 1200px width template.
Problem
The images must be resized to a width of 1200px while maintaining their original aspect ratio and converted to PNG.
How to Use
Upload the 15 product images, select 'PNG' as the output format, enter 1200 in the Resize Width field, and check 'Maintain Aspect Ratio'.
Example Config
