Resize an Image

Make a picture smaller for the web, or larger for print. Give exact pixels, or scale the whole thing by a percentage.

Files are never uploaded

How to use it

Add your images

Drop one or more pictures above, or click to browse. JPG, PNG and WebP all work, and the same settings are applied to each.

Choose how to resize

Percentage shrinks or grows a picture while keeping its shape — 50% halves both sides. Exact pixels is for when a website or a form demands a particular width.

Fill in your numbers

In pixel mode, enter a width and leave the height at 0 to keep the proportions, or fill both to force an exact size. With "keep the aspect ratio" on, the second box follows the first.

Set the output format

JPEG keeps files small and suits photographs. PNG preserves sharp edges and transparency; WebP is smaller still but not accepted everywhere.

Download the results

Each resized picture is saved with its dimensions in the file name, so versions are easy to tell apart.

Common issues

A picture came out stretched

That happens when both width and height are filled with a shape that does not match the original. Clear the height box, or turn on "keep the aspect ratio", to avoid it.

The output is much larger than the input

A format change is usually the cause — a compressed JPEG saved as PNG grows several times over. Choose JPEG for photographs.

Fine text became unreadable

Shrinking a screenshot or a scanned page quickly destroys small lettering. Resize less aggressively, or start from a higher-resolution original.

Transparent areas turned white

JPEG cannot store transparency. Choose PNG or WebP when it matters.

Frequently asked questions

Does resizing reduce quality?
Making a picture smaller is nearly lossless — the removed pixels are gone, but what remains looks sharp. Making it larger invents no new detail, so it will look softer than a photo taken at that size.
What does leaving a box at 0 do?
It tells the tool to work that dimension out from the other one, keeping the proportions. Leave both at 0 in pixel mode and the picture simply keeps its original size.
Can I resize several pictures at once?
Yes. Add as many as you like and the same settings are applied to each, with one file produced per picture.
Which format should I choose?
JPEG for photographs, PNG when sharp lines or transparency matter, WebP when you want the smallest file and know the destination supports it.
Will transparency be kept?
Only with PNG or WebP. JPEG has no transparency, so transparent areas are filled with white.
Can I make a picture larger?
Yes, up to 400% in percentage mode. The extra pixels are interpolated, so a small photo enlarged a lot will look soft — that is a limit of the source, not of this tool.
Why did the file get bigger after shrinking?
Usually because the format changed: a compressed JPEG re-saved as PNG grows several times over. Keep the format, or choose JPEG, to see the size drop.
Can I set a maximum width only?
Yes — put the limit in the width box, leave the height at 0, and keep "keep the aspect ratio" on. Tall and wide pictures then both fit within that width.
Is anything uploaded?
No. Pictures are decoded, resized and re-encoded entirely in your browser.
