What is Image Compressor?

Image Compressor reduces the file size of any image format — JPG, PNG, WebP, GIF, BMP, AVIF and more. Output as JPEG (smallest), WebP (best quality-to-size), or PNG (lossless). Achieves up to 90% size reduction on typical photos.

How It Works

Drop your images, pick an output format and quality level. The tool re-encodes each image using the browser's native canvas engine — no server upload, no third-party processing. JPEG and WebP compression is lossy but virtually indistinguishable at 70–80% quality. PNG output is lossless. Each image is processed individually so you get maximum compression.

How to Use

  1. 1

    Upload images

    Drop one or more images (JPG, PNG, WebP, GIF, BMP, AVIF, TIFF) onto the upload zone or click to browse.

  2. 2

    Choose output format

    Select JPEG for the smallest files, WebP for best quality-to-size ratio, or PNG for lossless output.

  3. 3

    Set quality level

    Drag the slider. 70–80% gives excellent results for most photos with 70–90% file size reduction.

  4. 4

    Compress

    Click "Compress". Each image is re-encoded in your browser using the native canvas engine — no uploads needed.

  5. 5

    Download

    Download each compressed image individually or get all files packaged in a single ZIP archive.
