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

Social-ready pixels without a cloud upload

Resizer applies the width and height you enter on a client-side canvas — not a social-media API that receives your files first. Type Instagram, LinkedIn, or Facebook targets from your own dimension reference, toggle aspect-ratio lock, and download or copy the output. It does not include a built-in dimension chart, one-click platform presets, or per-network crop overlays.

Why set image dimensions for social media in the browser?

Cloud resizers upload every asset before pixels change. Pix-8 processes locally — the practical path when you need image dimensions for social media applied at exact pixel sizes across platforms without a server round-trip.

Enter any platform's pixels

Set width and height manually — Instagram feed, LinkedIn profile, Facebook cover, or any target from your dimension reference — with optional aspect-ratio lock.

Client-side processing

Each image is read locally and resized on a canvas in the browser. Nothing is uploaded before you post to a social platform.

Batch or single export

Resize one asset or queue multiple images at the same dimensions — with optional EXIF stripping before download.

Frequently asked questions

Can I resize images to social media dimensions without uploading?

Yes. Pix-8 Resizer runs entirely in your browser. Load your image locally, enter the width and height your platform requires — such as 1080×1080 for an Instagram post or 820×312 for a Facebook cover — and download the result. Your file is read on-device and is never transmitted to Pix-8 or any third-party server.

What social media image dimensions can I set with this tool?

Enter any pixel width and height manually. Common targets include 1080×1080 or 1080×1350 (Instagram feed), 400×400 or 1584×1584 (LinkedIn profile), and 820×312 or 1640×624 (Facebook cover). Use aspect-ratio lock to keep proportions while adjusting one dimension. The tool does not include a built-in dimension chart, one-click platform presets, or crop overlays per network.

Is resizing to social media dimensions free and private?

Yes. The tool is free with no account required. All resizing runs client-side in your browser — your images stay on your device before you post to any social platform, with no cloud upload step.
