Frequently asked questions

Which formats are supported?

Upload JPG or PNG images and export in JPG, JPEG, or PNG.

Do my images leave the browser?

No. Everything runs locally using a web worker, so files never leave your device.

How does target size work?

Target size adjusts JPEG quality until the file is close to the size you specify.

Will EXIF rotation be applied?

We read EXIF orientation when possible and fall back to the original orientation if it cannot be detected.

Compress JPG and PNG for faster delivery

If your goal is a smaller file, ReduceImages gives you both quality-based compression and a target KB size option. Choose a lighter file for faster page loads, or keep higher detail for crisp images on high-resolution screens. You stay in control while the compressor handles the heavy lifting in the background.

The compressor is ideal when you need to reduce KB size without changing the look of your photo. Use the quality slider for creative control, or set a target size to meet upload limits for email, forms, or CMS tools.

How it works

  1. Upload a JPG or PNG file from your device.
  2. Pick a quality level or set a target KB size for the output.
  3. Download the compressed image instantly.

Image Compressor FAQs

Which image formats can I compress?

You can compress JPG, JPEG, and PNG files. Upload one image at a time and choose your preferred output format.

Can I compress to a specific KB size?

Yes. The compressor includes a target KB option so you can aim for a specific file size.

Will compression change my image dimensions?

Not unless you choose to resize. You can keep the original dimensions and focus purely on file size reduction.

Does compression remove metadata?

Exported images are re-encoded in the browser, which typically strips most metadata to help reduce file size.

Is there a quality slider for JPG compression?

Yes. Use the quality control to balance file size and visual clarity for JPG outputs.

Is the compressor private?

Absolutely. Everything runs locally in your browser, so your images are never uploaded.
