BatchForge: Bulk Photo Editor

BatchForge is a completely batch image processing tool. Resize hundreds of images, convert between formats, add watermarks, and rename files all at once. No internet connection required. Your privacy is 100 percent protected because all processing happens locally on your device. No uploads. No servers. Your images never leave your phone.
BATCH RESIZE MULTIPLE IMAGES
Resize hundreds of images in seconds with multiple resize modes. Scale by percentage from 25 percent to 400 percent of original size. Set custom width and height with optional aspect ratio lock to prevent distortion. Fit by long edge for social media preparation where you set maximum dimension. Fit by short edge for creating uniform thumbnails. Center crop to exact dimensions removing edges equally from all sides. These options work perfectly for product photos, social media posts, web images, and print preparation.
FORMAT CONVERSION FOR BATCH PROCESSING
Convert between multiple image formats across your entire batch. Output formats include JPEG for smaller file sizes, PNG for lossless quality with transparency support, WebP for modern web optimization, BMP for uncompressed format, and TIFF for professional printing. Adjust JPEG quality from 1 to 100 percent to balance file size against image quality. Remove EXIF metadata including GPS location, camera information, and date stamps to protect your privacy. Convert HEIC photos from iPhone to JPEG automatically. Batch convert entire folders of mixed formats to a single uniform format.
