What is image compression and why do I need it?

Image compression reduces the file size of your images by optimizing the data within them. This is crucial for websites because smaller images load faster, improving your SEO rankings and user experience. It also saves storage space on your devices and servers.

What is the difference between specific formats?

JPEG is best for photographs with many colors. PNG is best for graphics with sharp edges or transparency. WebP is a modern format that provides superior compression for both images and graphics, often 30% smaller than JPEG.

Does this tool remove EXIF data?

Yes. When you compress an image with this tool, metadata like GPS location, camera settings (EXIF), and other hidden data are typically stripped out, which further reduces file size and protects your privacy.

What quality setting is best for websites?

For most web images, a quality setting of 75-80% is the sweet spot. It significantly reduces file size (often by 70-80%) with virtually no visible difference to the human eye.

Is my data really private?

Yes. Unlike other tools that upload your photos to a cloud server to process them, this tool runs entirely in your web browser. Your photos never leave your computer or phone.

Can I compress very large high-res photos?

Yes. Since the processing is local, you are not limited by server upload caps. You can compress heavy DSLR or raw-converted JPEGs as long as your device has enough RAM.
