Shrink JPG, PNG, WebP, and AVIF images to a fraction of their size while keeping them sharp. Primova compresses in your browser using the same codecs (MozJPEG, OxiPNG, libwebp, libavif) that power professional pipelines — so you get smaller files without uploading anything.

How to use Image Compressor

  1. 1Drop one or more images onto the page, or click to choose them.
  2. 2Pick a target quality, or switch to “target size” to hit an exact KB budget.
  3. 3Watch each image compress with a live before/after comparison.
  4. 4Download a single image, or grab everything as a ZIP.

Frequently asked questions

No. Everything runs entirely inside your browser using your own device — your files never leave your computer or get uploaded anywhere. That makes it private and fast, even for large files.
You control the trade-off. At high quality the difference is invisible to the eye while the file gets dramatically smaller. Drag the slider down for even smaller files, and use the before/after comparison to find the sweet spot.
JPG/JPEG, PNG, WebP, and AVIF — both as input and output. You can also re-encode to a more efficient format (for example PNG → WebP) to save even more.
Yes. Add as many as you like, compress them in a batch, and download them all as a ZIP. Each file can also use its own quality if you open its detail view.
Yes, completely free with no sign-up, no watermark, and no daily limits. Use it as much as you like.
