Frequently Asked Questions (FAQ)
What is lossy vs. lossless compression?
Lossy compression reduces file size by permanently removing some data, which may slightly reduce quality. Lossless compression reduces file size without losing any image data.
How much can I reduce a JPEG's size?
Often, you can reduce a high-resolution JPEG by 70-80% without any noticeable drop in visual quality.
Are my compressed images safe?
Yes. Our tool is 100% serverless. All compression is handled locally by your browser's processing engine.
Does compressing a PNG preserve transparency?
Yes, our PNG compression methods maintain the alpha channel so your transparent backgrounds remain perfectly intact.
What is the best format for web compression?
WebP is currently the gold standard, offering significantly smaller file sizes than both JPEG and PNG at equivalent visual quality.
