Image Compressor FAQs
Lossy and lossless client-side compression
How does client-side image compression work?
Our tool uses your browser's native Canvas API. When you upload an image, it is rendered onto an off-screen canvas and exported at your selected quality scale and dimensions, compressing the file size directly in your browser.
Will compression reduce image quality?
Yes, if you choose lossy formats like JPEG or WebP and set quality levels below 100%. However, modern compression algorithms can reduce file sizes by 70% or more with virtually no visible loss of clarity to the naked eye.
What is the difference between JPEG, PNG, and WebP?
JPEG is best for photographs and offers lossy compression. PNG is lossless and supports transparency but results in larger file sizes. WebP is a modern format that supports both lossy and lossless compression with superior file size reduction.
Are my uploaded images secure?
Absolutely. Because the compression is processed 100% locally on your device, your images are never uploaded to any server. Your personal photos and documents remain entirely private.
