Private image compressor for JPG & PNG

TinyRaster is a lightweight image toolkit focused on privacy and performance. This compressor runs entirely in your browser using HTML5 canvas, so no image uploads, no server processing, and no waiting.

Drop a JPG or PNG file, choose an output format if needed, adjust the compression quality, and download the result in seconds. If you keep PNG as the output, compression is lossless and the size reduction may vary depending on the image content. For JPG output you'll get smaller files with a controllable trade-off between size and visual quality.

Pair this tool with the main JPG ⇄ PNG converter, the dedicated JPEG compressor, and the JPG/PNG → WebP converter for a complete optimization flow. If your images are too large in pixels, you can first use the image resizer and then come back here to fine-tune file sizes before publishing or sharing.
