Frequently asked questions

Is this image resizer really free?

Yes. Unlimited resizing, no account, no watermark, and no upload to a server — your image is processed locally in your browser.

What is the difference between pixels and percent?

Pixels set an exact target size (for example 800 by 600). Percent scales the original: 50% makes every side half as long, which cuts the total pixel count to about a quarter.

Which format should I choose — JPG, PNG, or WebP?

Use JPG for photos at 80–90% quality. Use PNG for logos or graphics that need sharp edges or transparency (files are larger). Use WebP for the best quality-per-byte on modern browsers.

Will resizing hurt image quality?

Shrinking an image keeps it sharp. Enlarging beyond the original size can look soft because no new detail is created — for best results, avoid scaling above 100%.

Features

Exact pixels or percent

Set a precise target like 800 × 600 for web layouts, or scale by percent — 50% cuts each side in half for a much smaller file.

Aspect ratio lock

The ratio lock keeps width and height proportional as you type, so photos never come out stretched or squashed.

Three output formats

Download as JPG for photos, PNG for sharp graphics and transparency, or WebP for the best quality-per-byte on modern browsers.

Quality control

A quality slider lets you fine-tune the balance between crisp detail and small file size.

Side-by-side preview

Compare the original and resized versions before downloading, so there are no surprises.

Generous file support

Handles JPG, PNG, WebP, GIF, and BMP images up to about 25 MB — bigger than most online resizers allow.
