Why use the Zenixbase Image Compressor
Smart compression
Re-encodes each image efficiently and never gives you a file that's bigger than the original.
PNG to WebP automatically
Large PNGs are converted to WebP with transparency kept, often saving 70% or more.
Resize while compressing
Cap the longest side to 4K, 1920px or 1280px: the biggest saving for phone photos.
Private by design
Compression runs in your browser, so your images are never uploaded.
Frequently asked questions
How much can I reduce my images?
Phone photos typically shrink by 60-90%, especially when you also cap the size to 1920px. Graphics saved as PNG often drop by 70% when converted to WebP.
Will people notice the quality loss?
With the Balanced level, the difference is not visible at normal viewing size. Use the before/after slider to check every image.
Is there a file size or count limit?
No fixed limit. Because processing happens on your device, very large batches simply take a little longer.
Does it remove photo metadata?
Yes. Re-encoding drops EXIF data such as GPS location, which also protects your privacy.
