About the Image Compressor

Large images are the single most common reason a page loads slowly. This compressor re-encodes your image at a quality level you control and shows the resulting file size immediately, so you can find the point where the file is small but the picture still looks right.

Everything happens on your own machine using the canvas API — the image is never uploaded, which makes this safe for photos of documents, screenshots containing customer data, or anything else you would not want sitting on someone else's server. You can also switch the output format while compressing; converting a photographic PNG to WebP or JPEG often cuts the size by more than the quality slider ever will.

Key features of the Image Compressor

Nothing leaves your device

Compression runs on the canvas API in your browser, which makes it safe for screenshots containing customer data or photos of documents.

Quality slider with live size

The output size updates as you drag, so you can find the exact point where the saving stops being worth it.

Side-by-side comparison

Original and compressed are shown together, because a percentage saving means nothing until you can see the picture.

Change format while compressing

Converting a photographic PNG to WebP or JPEG often cuts more than the quality slider ever will.

No queue, no upload wait

Work is local, so large files are processed at the speed of your machine rather than your connection.
