Only supported image formats are allowed!
- Upload Your Images: Drag and drop your files, click "Choose File," or import from URL, Google Drive, or Dropbox.
- Set Compression Quality: For each image, choose your desired quality. A lower percentage (like 50%) means a smaller file size but slightly lower quality. A higher percentage (like 80%) keeps more quality but results in a larger file.
- Compress: Click "Compress" for a single file or "Compress All" to process everything at once.
- Download: Your newly optimized images are ready to download with a smaller file size!
Why Did I Get "No Reduction"?
Sometimes, you might see "No Reduction" or even a slightly larger file size. This usually happens for two reasons:
- The image is already highly optimized. You can't squeeze any more data out of it without ruining the quality.
- For formats like PNG, which use lossless compression, our tool might not find a more efficient way to store the data than it already is.
Client-Side Processing
All compression happens right in your browser. Your image files are never uploaded to our servers, ensuring your privacy and data security.
No Data Logging
We don’t store, track, or log your uploaded images or their compressed versions. Your files stay on your device.
Completely Free
Zenfied's image compressor is 100% free to use, with no limits on the number of compressions or file sizes (within browser capabilities).
By using this tool, you agree to our Terms of Service and Privacy Policy. We ensure a server-free experience for your peace of mind.
PNG stands for Portable Network Graphics (PNG) was developed as an improved, non-patented replacement for the GIF format. It was officially released on October 1, 1996. PNG uses a lossless compression method, meaning no image data is lost during compression, resulting in perfect preservation of image quality.
PNG is widely used for web graphics, logos, icons, and images that require transparency. It supports millions of colors and various levels of transparency (alpha channel), making it ideal for images that need to blend seamlessly with different backgrounds. While excellent for graphics and images with sharp lines and text, PNG files can be considerably larger than JPEGs for photographs due to their lossless nature.
How to Open a PNG File:
- Windows: Use Microsoft Photos, Paint, IrfanView, or Photoshop.
- macOS: Open with Preview, Photoshop, or GIMP.
- Linux: Use GIMP, Eye of GNOME, or ImageMagick.
- Web: PNG files open directly in most modern web browsers like Chrome, Firefox, and Edge.
