How to Use Image Size Reducer

1

Enter the target file size in kilobytes or megabytes, matching the limit you need to satisfy.

3

Click the Reduce button and the image is re-encoded until it falls under your target.

4

Download the smaller file and check that the result still looks acceptable at 100 percent zoom.

Frequently Asked Questions

It depends on how aggressive the target is. Dropping a 6 MB photo to 300 KB is a large reduction and you will see some softening, while taking it to 1 MB is usually invisible.
The tool will shrink the file as far as it reasonably can and still hand you a download. An extremely high-resolution, very detailed image has a floor below which it will not stay usable.
Yes, and it is the most efficient way to prepare a consistent set for a marketplace listing or an upload form, since every file will land under the same limit.
It focuses on file size by re-encoding at an optimised quality. If you specifically need smaller pixel dimensions as well, run the file through the image resizer afterwards.

About Image Size Reducer

Most annoying upload failures are size failures. A marketplace listing rejects a 4 MB photo, a government form caps attachments at 2 MB, an email client quietly drops a 12 MB archive. The files themselves are usually fine, just a little heavier than the limit, and shrinking them is far less painful than reshooting the work.

This reducer takes jpg, jpeg, png and webp files of up to 20 MB and works to a target size you specify, rather than a quality number. Give it 500 KB and it will keep re-encoding and adjusting until the output fits under that ceiling while giving up as little quality as possible. That is a meaningfully different approach from a slider, because it optimises for the number that actually matters: the limit you are trying to clear.

Because the target is a ceiling rather than a guess, the result lands under your limit instead of near it. If an image simply cannot be made that small without looking bad, the tool will still produce the smallest reasonable version so you can see how far it can go before you change your approach.

When to Use This Tool

  • Getting a photo under the attachment limit of an email client or an online form
  • Meeting a marketplace or stock library upload ceiling such as 1 MB or 2 MB per image
  • Reducing a folder of images before sending it to a print shop or a client over a slow connection
  • Keeping a database, CMS or backup archive within a storage budget without visibly degrading the pictures
