How to Resize an Image Online Without Losing Quality

Resize images by percent or exact pixels, free in your browser. Keep aspect ratio locked, batch-process a folder, and never upload a single file.

Why the resize step keeps showing up

Almost every image workflow hits a size requirement: an avatar that must be exactly 512×512, a listing photo that the platform caps at 2000 pixels wide, an email attachment that should be under 1 MB. Resizing is the boring, necessary step between "take the photo" and "use it" — and it is a step that should take ten seconds, not a Photoshop session.

Resize by percent or by exact pixels

Two inputs cover every case. Percent resizing (e.g. 50%) is perfect for quickly producing a smaller version of a photo. Exact pixel resizing (e.g. 1280×720) is what you need when a platform or template specifies a precise size. The aspect ratio lock keeps proportions intact — stretch a portrait photo and everyone notices.

How to resize an image in three steps

  1. Open the Image Resize tool and upload one image or a whole batch.
  2. Choose "by percent" or "by pixels", enter the target size, and keep the aspect ratio locked (or uncheck it to crop instead of stretch).
  3. Download the resized images — processing runs locally in your browser.

Pair resizing with compression for speed

Resizing cuts dimensions; compression cuts weight. A 4000×3000 photo taken on a phone can be resized to 1600 pixels wide and then compressed, going from 5 MB to roughly 200 KB while looking identical on screen. For web use, resize first, compress second, and convert to WebP last for the smallest file your browser supports.

Keep an original of every photo. Resizing is lossy — a 2000px version cannot be upgraded back to the 4000px original. Store the source, share the resized copy.
