Frequently Asked Questions
What's the difference between JPG, PNG, and WebP?
JPG uses lossy compression and is best for photos with many colors. PNG uses lossless compression and supports transparency - ideal for graphics and logos. WebP is a modern format offering both lossy and lossless options with typically 25-35% smaller file sizes than JPG.
Will compressed images look noticeably worse?
At 80% quality and above, most people cannot detect a difference in photographic content. Text, sharp edges, and graphics may show artifacts at lower quality settings. Always preview before downloading to ensure acceptable quality.
Are my images uploaded to your servers?
All compression happens locally in your browser using JavaScript. Your images never leave your device, ensuring complete privacy. This also means compression works offline once the page is loaded.
What's the maximum image size you can compress?
Browser-based compression is limited by your device's memory. Images up to 20-30MB should work fine on most modern devices. Very large images (50MB+) may cause browser performance issues.
Should I use WebP format?
WebP offers superior compression and is supported by all modern browsers. Use WebP for web images to benefit from smaller file sizes and faster loading. For images that need broad compatibility (emails, older software), use JPG or PNG.
Pro Tips

- •WebP with 85% quality often beats JPG at 90% in both size and quality
- •Screenshot images work better as PNG or WebP than JPG
- •Reduce large original photos before uploading to websites
