How to use Resize image in 3 steps
-
Add images to resize

-
Enter the new size
With Resize by set to Pixels, fill in Width, Height or both. Switch to Percentage to scale proportionally; Scale starts at 50%.
-
Resize and download
Click Resize images, then download each file, grab the ZIP or save to Google Drive. For even smaller files, continue to Compress image.
Features
Resize image scales up to 20 pictures at once, either to pixel dimensions or by percentage. It’s the quick fix when a website, online store or application form wants photos exactly 1200 px wide, or when phone photos are too large to send. The aspect ratio is always kept: leave one field empty and the other side is calculated, fill in both and the image fits inside that box.
- Resize by pixels, up to 20,000 px per side, or by percentage from 10% to 400%.
- Enter only a width or only a height and the other side follows the original proportions.
- Enter both and the image scales to fit inside that box, never stretched or squashed.
- Up to 20 images per run with the same settings, plus a ZIP when there are several results.
- Keeps the original format: a PNG stays a PNG and a WebP stays a WebP.
- Results are renamed with “-doi-kich-thuoc” added, e.g. “product-01-doi-kich-thuoc.jpg”.
Frequently asked questions
Will my image be distorted if I enter both width and height?
No. The image scales to fit inside that box and keeps its proportions, so one side may come out smaller than you typed. In a 1200×1200 px box, a landscape photo ends up 1200 px wide and a portrait one 1200 px tall.
Does enlarging to 200% make a photo sharper?
No. Upscaling fills in new pixels from the existing ones without adding real detail, so the result can look softer. Start from the largest original you have.
How do I get an image of exactly 1280×720 px?
Since the ratio is always kept, first crop the photo to 16:9 with Crop image, then continue to Resize image and set the width to 1280 px.
Does making an image smaller reduce its file size?
Usually by a lot, because there are fewer pixels to store. If it’s still too heavy, send the result on to Compress image without uploading it again.
