Resize an image by dimensions or target file size

This image resizer helps prepare photos for online forms, profile images, documents and websites. You can reduce width and height while keeping the image proportional, or aim for a smaller upload size. Actual output size can vary because detailed photographs require more data than simple graphics.

Best way to get a smaller image

  1. Upload JPG, PNG or WebP.
  2. Choose sensible dimensions for the intended use.
  3. Reduce quality gradually instead of making the image unreadable.
  4. Download and check text, face details and orientation.

Dimensions versus KB

Pixel dimensions control physical resolution on a screen, while KB or MB measures stored data. Two images with identical dimensions may have different file sizes because their formats and visual complexity differ.

Frequently asked questions

Will resizing blur my photo?

Enlarging a small image can look soft. Reducing a large image usually remains clear when appropriate dimensions are selected.

Which format should I use?

JPG is practical for photographs, PNG for graphics requiring transparency, and WebP for efficient web delivery.

Is an exact target KB guaranteed?

No encoder can guarantee every image will reach an exact size without repeated adjustments, but the tool can create a close practical result.
