How to Batch Convert Multiple Images at Once

Converting images one at a time is tedious. Batch conversion lets you process dozens or even hundreds of images simultaneously, saving significant time when reformatting image libraries.

When You Need Batch Conversion

• Website migration — converting all images to WebP for better performance
• iPhone photo sharing — converting a batch of HEIC files to JPG
• Design handoff — converting design assets to a specific format
• Archive processing — standardizing an image collection to one format

How to Batch Convert

1. Choose your conversion type (e.g., PNG to JPG)
2. Select multiple files at once (use Ctrl/Cmd+click or select all)
3. All files process in parallel for maximum speed
4. Download each converted file individually

Privacy Advantage

Server-based converters upload all your images, which means every photo passes through someone else's server. Our batch converter runs entirely in your browser. Even when converting 50 images at once, nothing leaves your device.

Supported Batch Conversions

Batch conversion works with all our image formats. Popular batch conversions include:

• HEIC to JPG — iPhone photos
• PNG to WebP — web optimization
• WebP to PNG — compatibility
• TIFF to JPG — reducing file sizes

Performance Tips

For the fastest batch processing, convert 10-20 images at a time. Very large files (over 50MB each) may benefit from smaller batches. All processing uses your device's CPU, so a faster computer means faster conversions.
