FAQ

What image formats does the compressor support?

It supports JPEG, PNG, and WebP. You upload an image, adjust the quality slider, and download the compressed version — all processed in your browser using the Canvas API.

Will compressing an image reduce its quality noticeably?

At quality levels above 70%, the difference is usually imperceptible to the human eye. The tool shows a before/after file size comparison so you can decide the right balance for your use case.

Can I resize an image without changing its aspect ratio?

Yes. The Image Resizer has a "maintain aspect ratio" option enabled by default. When you change the width, the height adjusts automatically, and vice versa.

What color formats does the Color Picker support?

It converts between HEX, RGB, and HSL in real time. Pick a color using the native color input or type a value in any format, and the other formats update instantly.

Are my images uploaded to a server?

No. All image processing — compression, resizing, and color picking — happens entirely in your browser. Your files never leave your device.
