Why use this tool?
Use this free browser utility when you need a focused result without installing desktop software or creating an account. The workspace is designed for a single task, with the input, controls and output kept together.
Privacy, compatibility and limitations
Processing uses browser Canvas, may discard EXIF metadata, may change color profiles and cannot guarantee a target size. JPG removes transparency. PNG is lossless, so quality controls and target size do not guarantee shrinkage. Large images need device memory. Output can be larger than input if format/settings are unsuitable.
Questions about Image Compressor
Does the tool upload my photos?
No. Image processing runs locally in your browser.
What if the output is larger than the original?
The size report tells you. Try WebP, reduce dimensions or lower JPEG/WebP quality; do not replace the original if the result is larger.
Can I compress to a target size in KB?
You can request a target. The tool attempts to meet it by adjusting quality and dimensions; it reports when the target cannot be reached.
