How It Works

Step-by-step guide to resize png to exact specifications

Upload Your PNG Files

Drag and drop your PNG files or click to browse. Add a single file or up to 12 at once for batch resizing. JPG, PNG, WebP, and PDF inputs all work.

Set Your Dimensions

Enter the width and height you need in pixels, inches, cm, or mm. Lock the aspect ratio to keep proportions, or unlock it for an exact fit. The output stays as PNG.

Download Your PNG

Preview the result, then download your resized PNG instantly — or grab the whole batch at once. Nothing was uploaded, so your files stay yours alone.

Why Choose Imresizer?

Fast, secure, and completely free image resizing

  • Privacy Guaranteed

    Your PNG files never leave your device. Every resize runs locally in your browser, so nothing is uploaded and nothing is stored on a server.

  • Resize to Exact Dimensions

    Set any width and height in pixels, inches, cm, or mm. Your PNG comes out at the precise size a website, print lab, or upload form asks for.

  • Keep PNG Output

    Upload a PNG and download a PNG — the output format is preset for you. You can still switch to another format mid-resize if you need to.

  • Batch Resize Up to 12 Files

    Drop in up to 12 files at once and resize them all to the same dimensions in one pass. No repeating the same steps file by file.

  • Lock or Free the Aspect Ratio

    Keep your PNG in proportion to avoid stretching, or unlock the ratio to force an exact width and height. You decide which one matters.

  • Instant Results

    Because everything happens on your device, your resized PNG is ready almost as fast as you drop it in — no waiting on a slow upload.

  • Preview Before You Download

    Check the resized PNG next to your original before saving. If the size or crop looks off, adjust and re-export — you're never stuck with a surprise file.

  • Free & Unlimited

    Resize as many PNG files as you want, completely free. No account, no watermark on your output, and no daily cap.

Frequently Asked Questions

Everything you need to know about image resizing

How do I resize a PNG file?

Upload your PNG, enter the width and height you need, and download the result. The output is already set to PNG, so there's nothing extra to configure. The whole thing runs in your browser and takes a few seconds.

Is the PNG resizer free?

It's completely free with no limits. There's no paywall, no account to create, and no watermark added to your resized PNG. Resize as many files as you need.

Will resizing reduce my PNG quality?

Shrinking a PNG keeps it sharp, since you're removing pixels rather than inventing them. Enlarging well beyond the original can soften edges — for the cleanest result, start from the highest-resolution PNG you have.

Can I resize several PNG files at once?

Drop in up to 12 files together and resize them all to the same dimensions in one batch. It's faster than opening each PNG one at a time, and every file gets the same width, height, and format settings.

Are my files private when I resize a PNG?

Your PNG files never get uploaded. The entire resize happens locally in your browser, so they stay on your device the whole time. When you're done, you can clear them from browser storage for extra peace of mind.

What dimensions can I resize a PNG to?

Set any width and height in pixels, inches, centimeters, or millimeters. Pixels suit screens and social media, inches fit US print, and cm or mm match passport and ID photo standards. Lock the ratio to avoid stretching.

Do I need to install anything to resize a PNG?

No download required. The resizer runs in any modern browser on your phone, tablet, or computer. Open the page, drop in your PNG files, set the size, and download — there's nothing to install or sign up for.

Can I change the format while resizing my PNG?

Alongside resizing, you can switch the output to JPG, PNG, WebP, or PDF in the same step. So if a site needs a different format than your original PNG, you handle the resize and the conversion at once.
