About Image Compressor

This image compressor reduces file size by re-encoding your image at a lower quality setting or converting it to a more efficient format like WebP. You control the quality slider from 1 to 100, and the tool shows you the compressed file size in real time so you can find the right balance between quality and size. Optionally set a maximum dimension to downscale large photos, which further reduces file size. All processing uses the HTML5 Canvas API in your browser — no images are ever uploaded.

Frequently Asked Questions

How much can I compress an image?
Most photos can be compressed 50–80% by switching to JPG or WebP at 60–80% quality. The actual reduction depends on the image content and original format.
Is there any quality loss?
JPG and WebP compression is lossy — some detail is discarded to reduce file size. At quality settings above 70%, the difference is usually invisible to the eye. PNG compression is lossless but produces larger files.
What formats can I compress?
Upload any image your browser supports (PNG, JPG, WebP, GIF, BMP). Choose the output format: JPG for photos, WebP for the smallest size, or PNG for lossless output.
