How do I resize an image online for free?

Upload the photo above, choose width × height, percentage or file size, type the number and press Resize image. Then click Download. It is free with no sign-up and no credits, and the photo is resized in your browser, so nothing is uploaded to us. Use it as often as you like, on a phone or a computer, in any modern browser.

How do I resize an image to 20KB, 50KB or 100KB?

Choose File size (KB), tap 20, 50, 100 or 200 KB or type your own limit, and press Resize image. The tool first lowers the file weight, and only makes the picture smaller if it still does not fit. The new size is shown before you download, so you know it will pass exam, job or visa forms with a strict KB limit.

Is there a free image size changer online that resizes in KB?

Yes, this one. Pick File size (KB), type the target and download the result. It works the same for a passport photo, a signature scan or a product shot. If a very large photo cannot reach a tiny target like 5 KB, the tool keeps the smallest file it could make and tells you so. Resize image files in pixels first, or pick WebP, to get even smaller.

Can I resize image dimensions without stretching the photo?

Yes. Proportions are locked by default: type a new width and the height follows, so faces and logos keep their shape. Unlock the link icon only when a site demands a fixed box, and the edges are trimmed to fit, never stretched. To resize image files for social media, tap 1080 × 1080 for an Instagram square, 1920 × 1080 for YouTube or 1080 × 1920 for Stories.

Which image formats can I upload, and what do I get back?

You can open JPG, PNG, WebP, GIF, BMP and AVIF files up to 50 MB; results top out near 16 megapixels. You save a still JPG, PNG or WebP, so an animated GIF comes back as one frame, and see-through areas turn white in a JPG. HEIC photos from an iPhone do not open; save them as JPG first, then resize image files here.

Can I make a photo bigger with the image resizer?

You can, up to 400%, but enlarging here only stretches the photo, so it gets soft and blurry. To resize image files to a bigger size and keep them sharp, use the AI Image Upscaler on our home page. It adds real detail at 2K, 4K, 8K or 16K and uses credits, while this resizer stays free. Shrinking, on the other hand, always looks clean here.

Is my photo uploaded to a server when I resize it?

No. The photo is opened, resized and saved inside your own browser, and it never leaves your device. There is no account, no history and nothing stored on our servers for this tool. That makes it a safe way to resize image files like ID photos, documents or private pictures. Close the tab and it is gone, with nothing left behind to delete.

Can I resize many images at once, in one batch?

Not yet. The resizer works on one image at a time, which keeps it fast and simple in any browser. After you download, tap the small cross on the preview to remove it and add the next photo. Your chosen mode stays selected, so you can resize image after image in a few clicks. For a dozen photos, that is still only a couple of minutes.

Resize Image Online Free: by Pixels, Percent or KB

Get the exact size a website, form or social post asks for. Set width and height, a percentage or a target like 50 KB, then save as JPG, PNG or WebP.

Pixels, percent or KBJPG · PNG · WebPFree, no sign-up

Free, no sign-up. Your image never leaves your browser.

Three ways to resize image files with the image resizer

Every upload box has its own rule: a fixed size in pixels, a maximum file size, or just smaller please. Pick the rule you were given, type the number, and download. One image at a time, all in your browser, so even a slow connection or a private photo is no problem.

Resize image to exact width and height

Type the width or the height and the other side follows, so the photo never looks squashed. Unlock it when you need a fixed box, or tap a common size like 1080 × 1080.

Resize image in KB for forms and uploads

Job portals, exam forms and visa sites often want a photo under 20 KB, 50 KB or 100 KB. Type the limit and get a file that fits, saved as JPG or WebP.

Shrink a photo by percentage

Not sure of the numbers? Scale to 25%, 50% or 75% and the whole picture shrinks evenly. A 50% photo is a quarter of the area and usually far fewer KB.

Common sizes: 1080 × 1080 Instagram square · 1920 × 1080 YouTube / HD · 1080 × 1920 Stories · 1200 × 630 link preview
Target file size: 20 KB · 50 KB · 100 KB · 200 KB, or type any number up to 20 MB
Works with: Open JPG, PNG, WebP, GIF, BMP and AVIF up to 50 MB; save as JPG, PNG or WebP
Cost: Free to use, no sign-up, no credits, and nothing is ever uploaded
