BatchPix

BatchPix processes the images on your device in bulk. Everything runs on your device — your images and their information are never sent anywhere.

■ Convert
Convert JPEG, PNG, HEIC and more to WebP (lossy or lossless) or PNG in one go. Choose quality, resizing, output folder and naming. Keep Exif and XMP, or strip location data.

■ Edit metadata
Edit Exif (date taken, copyright, artist…) and XMP (title, keywords, rating, label…) for many images at once. Shift dates, remove only the location, or write the app's tags to XMP keywords. Preview before writing, and undo later.

■ Tag by rules
Build your own conditions, such as "if the folder contains 'Site' and the year is 2025 or later, add the tags 'Site' and '{year}'". Nest AND / OR / NOT groups, chain IF / ELSE IF / ELSE, use regular expressions, and match file names, folders, capture dates, Exif, XMP, image size and more. A dry run shows which tags will be added before anything changes.

■ Organize by tags
Move or copy the images you filtered by tags into folders named after tags or capture years. Choose how to handle duplicate names (number, skip or overwrite) and move everything back with Undo.

■ Library
Browse the images in your chosen folders as a grid or list. Filter by folder and tags, and select many at once with long-press, select all or drag. BatchPix doesn't use photo or media permissions — it only handles the folders you choose.

■ Built to be safe
• No network permission, no ads, no analytics
• Undo from the operation history (latest 30)
• English and Japanese

Requires Android 10 or later.
