Everything you need in a free image resizer

Exact pixel dimensions

Set any width and height in pixels — shrink for the web, enlarge for print, or match a platform’s required size.

Lock aspect ratio

Keep proportions when you edit one side, or unlock to stretch freely for banners, covers, and custom crops of scale.

100% browser-based

Everything runs locally on your device. Your images never upload to Focera servers — private by design.

Before & after preview

Compare the original and resized result with a slider, then download a PNG ready for design, social, or print workflows.

How It Works

Changing image dimensions should be fast and private. Focera keeps the whole flow on one page — upload, set size, resize, compare, and download without an account or desktop installer.

  1. Upload your image. Drag and drop a JPG, PNG, or WebP file up to 10 MB, or click the zone to browse from your device.
  2. Enter width and height. Use pixel inputs, keep Lock aspect ratio on for proportional resize, or pick a quick scale like 50% or 200%.
  3. Resize and download. Processing runs in your browser. Compare with the before/after slider, then download a PNG at the new dimensions.

Jump back to the image dimension resizer anytime to process another file.

FAQ

Is this image resizer free?

Yes. Upload, set dimensions, preview, and download with no account, subscription, or credit card.

Are my images uploaded to a server?

No. Resizing runs entirely in your browser. Your files stay on your device.

Can I set exact pixel dimensions?

Yes. Enter any width and height in pixels up to 8192 on each side. Use Lock aspect ratio to keep proportions, or unlock to stretch freely.

What do the quick scale presets do?

25%, 50%, 75%, 150%, and 200% set both dimensions relative to the original size while preserving aspect ratio.

Which image formats are supported?

Upload JPG, PNG, or WebP files up to 10 MB. The tool exports a PNG at the new dimensions.

How is this different from Upscale Image?

Resize Image sets exact width and height (or a percentage). Upscale Image enlarges by 2×–4× with optional detail enhancement for sharper enlargements.

Can I use the results commercially?

Yes. PNGs you download are yours to use in marketing, web, client work, and personal projects.
