Why use this tool

  • Type the exact width and height a form or website asks for.
  • Lock the aspect ratio so a face or a logo never comes out stretched.
  • Pairs with the compressor when a form also sets a KB limit: resize first, then compress.
When to use this
  • Matching an exact 1200x1200 pixel requirement for a marketplace or Amazon product listing
  • Scaling a banner image down by 50% so a page loads faster
  • Preparing a profile picture at the precise dimensions a platform requests
  • Resizing a batch of screenshots to a consistent width for a document or slide deck

Free and private. Everything runs on your own device, with no account and no uploads.

A marketplace wants a 1200 × 1200 product photo; a blog loads faster with the banner at half size. This tool resizes images by exact pixel dimensions or by percentage without installing any software. Resizing happens in your browser, so the image is not sent to a server.

Yes, lock the aspect ratio toggle so width and height scale together proportionally.

Yes, switch to percentage mode to scale the image up or down relative to its original size.

Common formats like JPEG, PNG, and WebP are all supported for upload and export.

Enlarging an image beyond its original resolution can soften detail, but shrinking it generally preserves visual quality well.

Pro tips
  • ·Lock the aspect ratio first, then adjust one dimension, the other updates automatically without distortion
  • ·Enlarging past the original resolution will soften detail, so try to resize down rather than up whenever possible
  • ·Use percentage mode when you just need a proportionally smaller version rather than an exact pixel target
