What this tool does

  • Resize by width and height in the browser
  • Lock aspect ratio toggle
  • Single-image and batch resize
  • Download or copy resized output
  • Optional EXIF metadata stripping before export
  • On-device processing — images never uploaded

Dimension control without a cloud upload

Resizer applies your width and height on a client-side canvas in the browser — not a cloud API that stores your file first. Toggle aspect-ratio lock, resize single images or a batch, then download or copy. It does not include preset platform crop sizes, AI upscaling, or server-side optimization.

Why change image dimensions in the browser?

Cloud tools upload before they resize. Pix-8 sets pixels locally — the direct path when you need to change image dimensions for listings, documents, or exports without routing files through a remote server.

Pixel-level control

Enter exact width and height in pixels. Lock aspect ratio to preserve proportions while you adjust one dimension.

Client-side processing

Dimension changes run on a local canvas in the browser. Your source file never touches a cloud server.

Batch or single export

Apply the same dimensions to one image or a batch, then download or copy — with optional EXIF stripping.

Frequently asked questions

Can I change image dimensions without uploading my file?

Yes. Pix-8 Resizer runs entirely in your browser. Load an image locally, enter target width and height, and export the result — your file is read on-device and is never transmitted to Pix-8 or any third-party server.

What image dimensions can I set with this tool?

Enter width and height in pixels, with an optional aspect-ratio lock that recalculates the paired dimension as you type. Resize a single image or a batch, then download or copy the output. Optional EXIF stripping is available before export. It does not include preset social-media crop sizes, AI upscaling, or server-side recompression.

How is changing dimensions in Pix-8 different from cloud resizers?

Cloud tools require uploading your image before dimensions are applied. Pix-8 changes width and height on a client-side canvas in your browser tab — free, with no account and no server round-trip.
