Batch Image Format Converter
Batch Image Format Converter is a free online tool that converts images in bulk between JPG, PNG, WebP, BMP, and GIF, and can also read HEIC/HEIF photos from iPhones. Adjust output quality and scale, then download images individually or grab them all as a ZIP.
All conversion happens locally in your browser — photos are never uploaded, so personal pictures stay private. Free with no registration, it's perfect for turning iPhone HEIC photos into JPG, batch-generating WebP for faster web pages, or standardizing image formats.

- Choose the target format: JPG, PNG, WebP, BMP, or GIF
- Adjust quality (10-100) and scale as needed
- Click Convert All, then download images individually or as a ZIP
