How to Compress PNG Files
The PNG Compressor by "HaruTools Lab" is a fast browser-based utility. While PNG files are known for their high quality, they often have large file sizes. This tool helps you reduce those sizes to improve website loading speeds and save storage space.
Key Features
- Batch Compression: Drag and drop multiple PNG files to process them all at once.
- No Installation: Runs directly in your browser, works on Windows, Mac, iOS, and Android.
- Privacy Focused: Your images are never uploaded to a server. All processing happens locally on your device.
Steps to Use
- Drag and drop the PNG images you want to compress into the designated area.
- Adjust the "Compression Level" slider (0.7 is usually the sweet spot between size and quality).
- Click the "Compress PNG" button.
- Review the preview and click "Save" to download your optimized files.
Frequently Asked Questions (FAQ)
Q. Will the transparent background be preserved?
A. Our high-efficiency compression logic utilizes JPEG conversion internally to achieve smaller file sizes. Consequently, transparent areas will be converted to solid white or black. If you must keep transparency, please use a dedicated "Image Resize" tool instead.
Q. Does compression ruin the image quality?
A. It depends on your slider settings. With a setting of 0.8 or higher, the file size is reduced while remaining virtually indistinguishable from the original to the human eye.
