Practical guide

How to use Compress Image

What this tool helps you do

Image compression reduces transfer size by removing redundant image data or encoding it more efficiently. The useful target is not the smallest possible file, but the smallest file that still looks acceptable at its intended display size.

When it is useful

  • Preparing product images for a website
  • Reducing an attachment before email
  • Improving page-load performance
  • Balancing photograph quality against storage

A practical example

For a 2400-pixel-wide product photograph that will display at 1280 pixels, set maximum width to 1280 and compare JPG at quality 80 with WebP at quality 80. Keep the version that meets the upload limit without visible damage. Actual byte savings depend on the source; no fixed percentage is promised.

Limitations and common mistakes

JPEG does not preserve transparency. Repeated lossy exports can damage fine detail. A PNG can already be efficiently compressed, so a new PNG may not be smaller. Keep the source file and inspect the downloaded output, not only the browser preview.

How to use Compress Image

  1. Choose one JPG, PNG or WebP image up to 50 MB.
  2. Choose the output format and adjust quality. PNG quality does not behave like JPEG quality.
  3. Keep original dimensions, or set a maximum width if the image is larger than needed.
  4. Click Compress Image. This sends the image to the server for the downloadable result.
  5. Download and compare the result at its intended display size, especially text and sharp edges.

Inputs and processing

JPG, PNG and WebP input, maximum 50 MB. The preview is generated in your browser; final compression uses the server. A smaller file is not guaranteed. If re-encoding does not save bytes and no resize was requested, the server can return the original image.

If something goes wrong

The file did not get smaller

Try a smaller maximum width or compare a suitable JPG/WebP export. The original may already be optimized.

Transparent areas changed

Use PNG or WebP when transparency matters; avoid JPEG.

The preview and download differ

Preview and final export use different encoders. Treat the downloaded file as the result to inspect.

Frequently asked questions

What quality should I choose?

Start near 80–85 for a JPEG photograph, inspect the preview, and lower it gradually.

Will dimensions change?

Compression does not need to change dimensions; use Resize Image when pixel dimensions are also too large.
