Frequently Asked Questions
How do I resize an image by percentage?
Upload the image, type the percentage (for example 50 for half size) and click Resize. Width and height are scaled by the same amount.
What does resizing to 50% mean?
Both width and height become half of the original. A 4000×3000 photo becomes 2000×1500 — a quarter of the pixels, so usually a much smaller file.
Can I enlarge an image by percentage?
Yes, enter a value above 100, such as 150 or 200. Enlarging can make photos look softer because no new detail is created.
Does scaling keep the aspect ratio?
Always. Because both sides change by the same percentage, the image never stretches or squashes.
How do I reduce the size of a photo for email?
Scale it to 25–50%. Phone photos are often 4000 px wide; at 25% they are still sharp on screen but a fraction of the size.
Will the image format change?
No. The scaled image is saved in the same format you uploaded.
Is percentage or pixel resizing better?
Use percentage when you want “smaller” or “bigger” quickly; use Resize Image by Pixels when a website or form needs an exact size.
Can I scale several images by the same percentage?
Use the Bulk Image Resizer for batches, setting the width you want for all of them.
Does resizing lower the image quality?
Scaling down keeps images crisp. Quality only drops noticeably when enlarging far beyond the original size.
Does the Resize by Percentage tool store my photos?
No. Scaling happens in memory and the photo is discarded immediately after you download the result.
