About This Tool
The Zaberz Image Compressor reduces image file size by adjusting quality and dimensions directly in your browser using the canvas API — no upload to any server required. Choose between JPEG, WebP, or PNG output, fine-tune the compression quality and resize scale, and optionally sharpen the result to counter softness introduced by resizing.
How to Use
- 1 Upload an image by clicking or dragging it in.
- 2 Choose a format, adjust quality and resize scale.
- 3 Click Compress, then download your optimized image.
Frequently Asked Questions
Use JPEG or WebP for photos, since they compress well with minimal visible quality loss. Use PNG when you need transparency or sharp edges, such as logos or screenshots. WebP usually gives the smallest file size for a given quality level.
Some quality loss is expected with JPEG and WebP compression, but at higher quality settings it's usually not noticeable. PNG compression is lossless, so quality stays the same regardless of file size reduction.
No, all compression and resizing happens locally in your browser using canvas. Your image is never uploaded or stored anywhere.
