Resize to 100% of the original. Width and height are both multiplied by 1, so the pixel count becomes 100% of what it was.

Percentage resizing is relative, so every image keeps its own proportions and no target size has to be worked out in advance.

What 100% does to common images

A larger image means a larger file, roughly in proportion to the number of pixels. The file size will stay about the same.

Reducing without losing the point of the picture

Reducing to 100% throws away pixels, and downscaling is where resampling quality matters. ResizeAny uses Lanczos-3, which weighs neighboring pixels so fine lines stay clean instead of turning jagged or smudged.

Check the result at 100% zoom. If a shrunken screenshot or scan has become hard to read, the percentage is too aggressive; step it up or choose a fixed pixel size that keeps the small text legible.

When percentage resizing makes sense

• A mixed folder of portrait and landscape photos where each should keep its own shape.
• A quick shrink for email or messaging when you have no target in mind.
• Enlarging a small graphic by a whole factor, though results get softer the further you go.
• Repeating the same change across a batch, using the bulk resizer.

How to resize an image to full height only

1. Add your image. Select a photo or drag it onto the box above. JPG, PNG, WebP, AVIF, HEIC and BMP files are accepted, and the file stays on your device.
2. Apply 100%. The preset scales width and height to 100% of the original. Each image keeps its own proportions relative to its size.
3. Download the result. Click resize and save. Check the new pixel dimensions and file size in the preview before downloading.
