How Image Compression Changes Your File

The homepage compressor creates a JPEG file and lets you adjust its compression quality. It does not currently offer an exact target file size or passport photo dimensions.

🚀 What the compressor does

The tool re encodes the selected image as JPEG, limits its width to 1920 pixels, and lets you adjust JPEG quality. The resulting size varies with the image and quality setting. Review the preview before downloading.

💎 Keep the original when needed

  • TransparencyJPEG does not retain transparent backgrounds.
  • DimensionsImages wider than 1920 pixels are scaled down.
  • Target sizeThe current tool does not accept an exact KB limit.

Frequently Asked Questions

How does the image compressor work?

Select an image, review the compressed preview, adjust JPEG quality with the slider, and download the result when it looks right.

Can I set an exact file size such as 20 KB or 100 KB?

No. The current homepage tool has a quality slider, but no exact target size field. Check the downloaded file against the limit required by your form.

Does the homepage compressor keep PNG transparency?

No. The current compressor creates JPEG output, which does not support transparency. Keep the original PNG if its transparent background is needed.

Are my images uploaded?

The compression code runs in your browser. The selected image is processed locally rather than sent to the site for compression.
