Reduce an image's file size with an adjustable quality slider.
Image files, especially photos straight from a phone or DSLR camera, are often far larger than needed for web use, email, or social media, which can slow down page load times, exceed upload limits, and take up unnecessary storage space. Compressing an image reduces its file size by adjusting the level of detail retained, typically with minimal visible quality loss at reasonable settings.
This matters most for website performance — large, uncompressed images are one of the leading causes of slow-loading pages — as well as for practical situations like email attachment limits or upload restrictions on forms and portals.
Upload your image, then adjust the quality slider to control the tradeoff between file size and visual quality. A live preview shows the result before you download, so you can find the smallest file size that still looks acceptable for your use case.
At moderate compression levels, quality loss is usually minimal and hard to notice on screen. Pushing the slider toward maximum compression trades more visible quality for a smaller file size.
Common formats like JPEG and PNG are supported. JPEG generally compresses more effectively for photos, while PNG is better suited to graphics with sharp edges or transparency.
No — compression reduces file size by optimizing image data, not by resizing the width or height. Use an image resizer if you also need to change the dimensions.
The compression happens in your browser, so your image isn't sent to or stored on an external server.
Compression efficiency depends on image content — photos with lots of fine detail and color variation compress less than simpler images with large flat areas of color.
