Lossy vs. Lossless Image Compression
Image optimization is about finding the perfect balance between visual clarity and file size reduction. Understanding the difference between lossy and lossless algorithms is key:
- •Lossy Compression: Removes non-essential, redundant metadata and fine pixel variations. Ideal for web graphics and photo sharing because it achieves significant file shrinkage.
- •Lossless Compression: Rewrites the image file structure mathematically without discarding any data. Perfect for corporate logos, text screenshots, and graphics requiring pixel perfection.

Frequently Asked Questions
Does compressing an image reduce its quality?
It depends on the compression type. Lossless compression reduces file size without changing a single pixel (perfect for PNGs). Lossy compression (like JPEG and WebP) discards minor visual detail that the human eye can rarely detect to achieve 70-90% smaller file sizes.
What file formats are supported for compression?
Our tool fully supports JPEG/JPG, PNG, WebP, and iPhone HEIC files. You can also output your compressed images in modern formats like WebP to speed up your website loading times.
How much can I reduce my image file size?
You can typically expect a 50% to 80% reduction for JPEGs and WebP files without noticeable quality loss. For transparent PNG files, compression usually reduces size by 30% to 60%.
Are my images secure during the compression process?
Yes, your images are processed locally on your client machine or via ephemeral secure memory on our servers. Your original and compressed photos are never permanently stored, and we do not use them to train any models.
