What is the Free Image Compressor?
The PrivatePhotoSuite Image Compressor reduces photo file sizes using quality compression, making images faster to load and easier to share — all without uploading your files to any server. You can preview the before/after difference with a drag-to-compare slider, choose a quality preset (Web, Balanced, Print, or Maximum), and batch compress up to 20 images at once.
Why compress images without uploading?
Most image compression services work by uploading your photo to a remote server, compressing it there, and sending it back. Your photos — which may contain personal or sensitive content — are exposed during transit. PrivatePhotoSuite's compressor runs entirely in your browser using the Canvas API's toBlob() method. Your images never leave your device.
Frequently Asked Questions
How much can I compress an image?
Typical reductions are 40–80% depending on the image and quality setting. WebP format often achieves the smallest file sizes for the same visual quality.
Which format gives the best compression?
WebP generally produces smaller files than JPG at the same quality setting, while maintaining excellent visual quality. JPG is the most universally compatible format.
Does compression damage my photos?
JPEG and WebP compression are lossy — some detail is lost. At quality 80+ the difference is typically invisible to the human eye. PNG compression is lossless, so no quality is lost.
Can I compress PNG images?
Yes. You can upload PNG files. Note that PNG with transparency will lose transparency if you output as JPG. Use WebP or keep as PNG to preserve transparency.
