What is an Image Compressor?
An Image Compressor reduces an image's file size by optimizing or reducing embedded data, while aiming to preserve visual quality.
Our free Image Compressor supports JPG, PNG, and WebP files, letting you shrink images for faster page loads and easier sharing.
Compressing an image involves a genuine tradeoff between file size and visual quality, and understanding the difference between lossy and lossless compression helps explain what you're actually choosing when you adjust a quality setting. Lossy compression, the more common approach for photos, permanently discards some image data to achieve a smaller file, while lossless compression reduces file size without removing any visual information at all, resulting in a larger file but pixel-perfect fidelity to the original.
Our Image Compressor handles JPG, PNG, and WebP files, applying the appropriate compression approach for each format. Photos, which contain a lot of naturally repetitive color data, often compress by 50 to 80 percent with minimal visible quality loss, while simple graphics and screenshots can sometimes compress even further, since they contain even more redundant, repeatable data for the compression algorithm to work with efficiently.
PNG and JPG compression work meaningfully differently under the hood. PNGs are typically compressed losslessly by optimizing their internal file structure rather than discarding visual data, while JPG compression usually involves an actual quality slider that trades some visual fidelity for a smaller file size, meaning JPG compression is inherently a more direct quality-versus-size decision than PNG compression is. Batch uploading, when supported, lets you compress an entire folder of images together and download them as a single zip file, which is considerably faster than compressing images one at a time through a browser interface.

Best Practices for Using an Image Compressor
- Start With Moderate Compression — Increase strength only if file size is still too large
- Use WebP for Web Images — Often produces smaller files than JPG at similar quality
- Keep an Original Copy — Save the uncompressed version before compressing
- Check Visual Quality Afterward — Confirm compression didn't introduce visible artifacts
- Batch Compress When Possible — Process multiple images together to save time
