Below, I'll decode several online tools for batch brightening, guiding you step-by-step through the operation secrets so you can handle it with ease. Each tool comes with a detailed comparison of pros and cons, allowing even beginners to quickly make a choice and become an instant photo-editing expert. Say goodbye to the pain of manually retouching images one by one, and watch your image processing efficiency soar!

Why do we need to batch brighten images like JPG and PNG?

1. At events like weddings, concerts, or team-building activities, the lighting is often incredibly complex. As an event photographer, you're bound to have some failed shots. Batch brightening can unify the brightness of all photos, making every image clear and beautiful.
2. E-commerce displays require retouching to create a unified visual style, compensating for inconsistencies like varying background cloth colors or light/dark differences caused by shooting at different times of day.
3. Scanned old contracts and archive files often have a grayish background, making the text look hazy. Phone photos of documents, taken in poor light, become too blurry to recognize when printed.
4. When sharing on social media, batch brightening ensures a consistent tone across a nine-grid layout.
