Resize by exact width and height

This page is for pixel-perfect sizing. It starts in custom dimensions with aspect ratio locked. Enter the width or height you need. Upscaling stays off unless you enable it. Crop, rotate, and flip are available before encoding. For a shareable deep link, open /resize/WIDTHxHEIGHT (for example /resize/1200x400).

How to use

  1. Add an image. Its current width and height fill the size fields.
  2. Change the width or the height. The other side updates while aspect ratio is on.
  3. Optionally crop, rotate, or flip before encoding.
  4. Choose the output format and quality or target size, then convert.

Key benefits

  • Exact pixels

    Target a specific width and height for thumbnails, product shots, or layout slots.

  • Aspect ratio stays

    A 4000 by 3000 image can become 3200 by 2400. It will not become 3200 by 3000 while the lock is on.

  • No upscaling by default

    Asking for a larger size than the original keeps the original dimensions unless you allow upscaling.

Exact size versus percentage

Use this page when you know the pixel box you need. For scaling everything by 50% or capping the longest edge, open resize by percentage or max edge.

Resizing changes how many pixels the image has. Compression changes how those pixels are stored. If the goal is a file under 100 KB, start with target size compression.

Batch and presets

Width presets help when many photos need the same pixel width. Each file keeps its own aspect ratio.

For framing, open crop image. For orientation, open rotate image.

FAQ

Common questions

Will the resizer stretch my image?

Not while keep aspect ratio is on. Width and height stay in the same proportion as the original.

Can I make an image larger?

Only if you enable Allow upscaling. By default, dimensions above the original size are brought back down to the original.

What is the difference from Resize Image?

Image Resizer focuses on exact pixel width and height. The Resize Image page starts with percentage and max-edge modes for batch scaling.

Does resizing upload the image?

No. The resized file is created in your browser.

Can I resize several images?

Yes. The same settings apply to each image in the batch, without enlarging any of them unless upscaling is on.
