Frequently Asked Questions
Everything you need to know about compressing images with GenieTools.
- How much can I compress an image?
- Up to 90% depending on the image content and the quality setting you choose. Photos with lots of detail compress well with JPEG or WebP output, while simple graphics may compress less dramatically.
- Will compression reduce visible quality?
- At 80% quality and above, differences are barely noticeable to the human eye. The quality slider lets you find the perfect balance — lower settings produce smaller files but more visible compression artifacts.
- What formats are supported?
- PNG, JPG, and WebP are accepted as input. You can output as JPEG or WebP for the best file size reduction, or keep the original format.
- Is there a file size limit?
- 20 MB per image. Very large images may take a few seconds to process in older browsers, but there is no hard cap on the number of images you can compress.
- Is my image uploaded to a server?
- No — all compression happens entirely in your browser using the Canvas API. Your images never leave your device and are never stored anywhere.
- Can I compress PNG to JPG?
- Yes. Select JPEG in the output format dropdown before clicking Compress. Transparent areas will be filled with a white background automatically.
- Does it work on mobile?
- Yes, any modern browser on iOS or Android supports this tool. No app installation is needed.
- Why is WebP smaller than JPEG?
- WebP uses a more efficient compression algorithm developed by Google. It achieves 25–35% smaller file sizes compared to JPEG at equivalent visual quality, and also supports transparency like PNG.
