DIMENSION DRAFTING TABLE / 01

Draft image dimensions, then inspect the returned frame

Choose one JPEG, PNG, or WebP image up to 25 MB and 25 million pixels. Enter width and height in pixels, keep the aspect ratio when needed, or use the visible 50%, 75%, 150%, and 200% presets.

Open image resizing

Set the dimension draft before resizing

The editor exposes two pixel fields, an optional aspect-ratio switch, and four percentage tokens. These controls describe the requested target frame; they do not remove the fixed checks applied to every operation.

Pixel fields

Enter positive whole-number width and height values in pixels.

Aspect-ratio switch

When switched on, changing one dimension updates the other from the source ratio.

Scale tokens

Choose one of the visible 50%, 75%, 150%, or 200% tokens to draft both dimensions.

Place, set, resize, and review

One image moves through one dimension draft. The source frame supplies the starting measurements; the returned frame supplies the result measurements and preview.

  1. 1. Place one source image

    Select one JPEG, PNG, or WebP image. The tool reads the source width and height before dimensions are set.

  2. 2. Draft the target frame

    Enter pixel dimensions, choose whether the aspect ratio follows, or apply one of the four percentage tokens.

  3. 3. Review the returned frame

    Read the result dimensions, inspect the preview, download the output, and check it before use.

Four boundaries are protected for every operation

Input type, input bytes, input pixels, requested output pixels, and returned output bytes are checked. The output remains in the decoded input format: JPEG remains JPEG, PNG remains PNG, and WebP remains WebP.

  • 01 — JPEG, PNG, or WebP image per operation
  • 25 MB — maximum input bytes
  • 25 MP — maximum input and output pixels
  • 50 MB — maximum returned output bytes

Treat dimensions, preview, and download as separate checks

The result reports the returned width and height and shows a preview. Download the returned file and check it in the context where it will be used.

  • Read returned width and height
  • Inspect the visible preview
  • Download and check the returned file

Questions about image dimensions

Which image formats can I resize?

One JPEG, PNG, or WebP image can be used for each operation. The returned image uses that same input format.

What happens when aspect ratio is enabled?

Changing one pixel dimension updates the second dimension automatically from the source image ratio.

Which limits apply?

Input is limited to 25 MB and 25 million pixels. Output is limited to 25 million pixels and 50 MB.
