Image Compressor
What is Image Compressor?
Reduces an image's file size by re-encoding it at an adjustable quality level — useful for speeding up websites, reducing upload sizes, or fitting attachment limits.
How to use Image Compressor
Choose an image file, pick JPEG or WebP as the output format, then drag the quality slider to balance file size against visual quality. A live preview and before/after file size comparison update as you adjust it, and you can download the compressed result.
Understanding your result
Lower quality settings produce smaller files but can introduce visible compression artifacts, especially on images with sharp text or fine detail. For photos, quality settings around 60–80% usually give a good balance.
Frequently Asked Questions
Is my image uploaded to a server?
No — compression happens entirely in your browser using the HTML canvas, so your image never leaves your device.
JPEG or WebP — which should I pick?
WebP usually compresses smaller at the same visual quality and supports transparency; JPEG has the broadest compatibility with older software. If your image has a transparent background, use WebP — JPEG has no transparency and will fill it in.
