Scale Image by Percentage

How do I reduce image size by 50%?

Select 50% on the scaling slider. This halves both width and height, reducing the total pixel count to 25% of the original. File size typically decreases by 60-80%.

How do I make an image twice as large?

Set the scale to 200%. This doubles both dimensions, quadrupling the total pixel count. Quality depends on the resampling algorithm - advanced methods minimize blur from enlargement.

What percentage should I use to reduce file size for web?

Scale to 50-75% for most web uses. A 4000x3000 photo becomes 2000x1500 at 50%, which is ample for most screen sizes while significantly reducing file size.

Can I upscale a small image to make it larger?

Yes, but quality depends on how much you enlarge. Up to 150-200% usually looks acceptable. Beyond 300%, images become noticeably soft or pixelated regardless of algorithm used.

How do I calculate the new image dimensions?

Multiply original dimensions by the percentage divided by 100. For example: 1000px at 75% = 1000 × 0.75 = 750px. Both width and height scale proportionally.

What is the best percentage for Instagram photos?

Instagram displays images at 1080px width maximum. If your photo is 4000px wide, scale to 27% (or resize by pixels to 1080). Larger images are compressed by Instagram anyway.

How do I reduce image size for sending via WhatsApp?

Scale to 50% for quick sharing. WhatsApp compresses images heavily regardless, so starting smaller reduces quality loss. For important photos, send as a document instead.

Why does my resized image look blurry?

Either the quality setting is too low, or you are enlarging beyond what the original resolution supports. For photos, avoid scaling above 150%. For graphics, higher scaling works better.
