FAQ
How is the image compressed?
The image is redrawn onto a canvas and re-encoded at your chosen quality level using the browser's native image encoder - PNGs are converted to WebP for better compression, other formats keep their original type.
Why does filename and alt text matter for SEO?
Search engines can't "see" an image, so descriptive filenames and alt text (rather than IMG_1234.jpg) help image search and accessibility tools understand what's in the picture.
Does compression reduce image quality noticeably?
At 70-85% quality, most photos look visually identical while file size drops significantly. Lower the quality slider further for smaller files at the cost of visible compression artifacts.
Is my image uploaded anywhere?
No - compression happens entirely in your browser using the Canvas API. The image file never leaves your device.
