Oversized images are the single most common reason a web page feels slow. A photo straight from a phone camera easily weighs 4-6 MB, yet the very same picture, at the same visible quality, often fits into a few hundred kilobytes. Our Smart Image Compressor closes that gap: it re-encodes your pictures at a quality level you choose and typically cuts file size by 60-80% while the result still looks identical on screen.
Everything happens inside your own browser using the Canvas API — your photos are never uploaded, never queued on a server, and never stored anywhere. Drop in a whole batch at once, watch the before and after size for every file, then download them one by one or all together.
Reduce size by up to 80% while maintaining quality.

Compression runs locally in your browser, so your photos never leave your device and no copy is ever kept.
A live slider from 10% to 95% lets you trade size against detail until the result is exactly what you need.
Compress dozens of images in a single pass and download them all with one click.
At the default 70% quality most people cannot tell the difference on screen. Lowering the slider a long way will eventually show softness or blocky areas, so preview the result before you keep it.
Common web image formats including JPG, PNG and WebP. Each file is re-encoded using the quality level you select.
There is no server limit, because nothing is uploaded. The practical ceiling is your own device memory — very large batches simply take a little longer.
No. Images are processed in memory inside your browser and disappear the moment you close or refresh the page.
