Why are some images so large?

File size mostly follows the number of pixels. A modern phone camera takes 12 megapixel photos or more, which is about 4,000 by 3,000 pixels, and saves them as 2 to 6 MB. Most forms and websites do not need that. A website image rarely needs more than 2,000 pixels on its long side, and a profile picture needs far fewer.

Compressing and resizing are different

  • Compression keeps the pixel size and stores the same picture with less detail where the eye does not notice it.
  • Resizing reduces the number of pixels. It is the biggest saving, because halving the width and height leaves a quarter of the pixels.

This tool does both. Use the quality setting for compression and the Max width or Max height boxes for resizing. With a target size, it uses compression first and resizes only when it has to.

Compress an image in three steps

  1. Add the picture.
  2. Leave the format as Same as original and the quality at 80, or choose a target such as 200 KB.
  3. Look at the saved percentage in the list, then download.

If the result is still too big, lower the quality a little or set a smaller Max width. If it looks soft, raise the quality or choose a larger target.

Built-in alternatives

On a Mac, Preview can export a JPG with a quality slider. On Windows, Paint can resize by percentage or pixels. Both work on one file at a time and give you no size target, which is where an online tool helps, especially for batches.

Frequently asked questions

How can I reduce the size of a photo without losing quality?

Use quality 80 to 85 and resize to the largest size you really need. At that level the loss is rarely visible at normal viewing size.

How do I compress an image to a specific size?

Choose a target such as 100 KB or 1 MB in the Target size list, or use one of the size pages. The tool finds the best quality that fits.

Does compressing change the image dimensions?

Not unless you set a Max width or Max height, or the target size cannot be met by quality alone. Then it scales down as little as it can.

Is it free?

Yes, with no sign-up and no watermark.
