Browser-based

Upload a JPG, PNG, WebP, or GIF and compress it in your browser. Choose Light, Balanced, or Strong compression and output as Auto, JPEG, or WebP. Auto tries both formats and keeps the smaller file. Very large images may be resized. Files are not uploaded to a server.

What to do next

How to use this tool

1. Choose a JPG, PNG, WebP, or GIF file. 2. Pick compression level and output format. 3. Click Compress image. 4. Compare original vs compressed size in the preview. 5. Resize first if dimensions are larger than you need for the web.

Worked example

Example: a 2.4 MB phone photo at 80% quality WebP might drop to about 420 KB with little visible loss on a laptop screen.

Common examples

  • 2.8 MB hero JPG at 80% quality WebP → often under 500 KB for blog headers.
  • 4 MB product PNG → JPEG export at 85% for catalog listings when transparency is not needed.
  • Batch of blog images resized to 1200 px wide then compressed → faster LCP on static sites.

How it works

Upload a JPG, PNG, WebP, or GIF image, choose a compression level and output format, then compress. The tool may resize very large images and tries multiple quality settings (and WebP plus JPEG in Auto mode) to find a smaller file. Processing runs in your browser—files are not uploaded to a server.

Limitations

Compression is lossy for JPEG output. Very small images or transparent PNGs may not shrink much without visible quality loss.

Privacy and file handling

Important notice

Compression is lossy for JPEG output. Very small images or transparent PNGs may not shrink much without visible quality loss.

Frequently asked questions

What do the compression levels do?

Light keeps higher quality and larger dimensions. Balanced is a middle ground. Strong uses lower quality and a smaller max dimension for the smallest files. Each level also tries lower qualities if needed to beat the original size.

Which formats are supported?

You can upload JPG, PNG, WebP, or GIF. Output can be Auto, JPEG, or WebP. Auto tries WebP and JPEG and keeps the smaller result.

Are my images uploaded to a server?

No. Compression runs entirely in your browser. Files are not uploaded or stored by Utilnivo.
