How do I resize an image in KB?
Set the width and height, turn on Limit file size and pick 20, 50 or 100 KB. The file lands under it at the size you typed.

How to resize an image
Change image dimensions in three steps.
Add images to resize
Drop JPG, PNG or WebP photos on the box, or choose them from your device. Each card shows its width and height.
Set the new size
Type a width in pixels and the height follows, or pick a size such as Instagram post. Percent and cm work too.
Resize and download
Press Resize and each card shows its new pixels and KB. Download saves one image, or a ZIP holding all of them.
Resize a photo in KB for any form
Exam, job and visa forms often ask for two things at once: a photo of, say, 200 × 230 pixels and a file under 50 KB, or a signature of 140 × 60 pixels under 20 KB. Type the pixel size, turn on Limit file size and pick the KB value from the form.
The image is resized to your exact width and height first. Then the quality is lowered only as far as needed to fit under the limit, so the pixel size the form checks never changes, and the card shows the final KB.
If the form only cares about KB and not pixels, Compress Image is the quicker route: it shrinks the file and keeps the width and height exactly as they are.
Resize image in cm or inches for print
Printers and print shops talk in cm, inches and DPI (dots per inch), while screens count pixels. Choose Print size, enter the width in cm or inches and a DPI, and the pixels are worked out for you: 10 cm at 300 DPI is 1181 pixels.
The DPI you set is also saved inside JPG and PNG files, so Word, Photoshop and print apps open the image at the right paper size. WebP has no place to store DPI, so print files are best kept as JPG or PNG.

Pixels, percent or cm
Give an exact width and height in pixels, scale by a percent, or set a print size in cm or inches.
Sizes for social media
Pick Instagram post or story, a YouTube thumbnail or Full HD, and the right pixels are filled in.
Crop, pad or stretch
Change the aspect ratio your way: trim the edges, add a border so nothing is cropped, or stretch it.
Resize to a size in KB
Turn on Limit file size and pick 20, 50, 100 or 200 KB. Your width and height stay exactly as typed.

Questions about resizing images
Can I resize an image without losing quality?
Making it smaller keeps it sharp, as each new pixel blends many old ones. PNG output is lossless; JPG is saved at quality 90.
How do I change the DPI of an image?
Choose Percent, keep 100%, and type a DPI such as 300. The pixels stay the same and only the print size in the file changes.
How do I resize an image for Instagram?
Pick Instagram post, portrait or story under Size. Choose Add border to keep the whole photo, or Crop to fill the frame.
How do I increase image size?
Type a width larger than the original. It is smoothly enlarged, which makes it bigger but cannot add detail that was not there.
Can I resize multiple images at once?
Yes. Add as many as you need, up to 100 MB each. They share one size setting and arrive together in a single ZIP file.
How do I convert pixels to cm?
Divide the pixels by the DPI and multiply by 2.54. At 300 DPI, 1200 pixels are 10.16 cm; Print size does this sum for you.
Is resizing the same as compressing?
No. Resizing changes the width and height; compressing makes the file lighter at the same pixel size. Compress Image does that.
