Target file size
Enter a size between 1 KB and 50 MB.

Each image is saved just under this size. 1 KB counts as 1,000 bytes, so files also pass the strictest upload checks.

Output format

PNG cannot be shrunk by quality, so PNG files are saved as JPG or WebP. Only WebP keeps transparency: JPG gets a white background. With "Same as original", a transparent PNG becomes WebP and any other PNG becomes JPG.

Dimensions

When lowering the quality is not enough to reach the size, the image is scaled down step by step until it fits.

Optional: images larger than this are scaled down first, keeping their proportions.

Your images never leave your device: everything runs in your browser.

About Compress Image to KB or MB

This free tool compresses an image to the exact file size you need: 20 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, 2 MB or any size you type. It is made for upload limits on application forms, job portals, email attachments, marketplaces and website builders, where a photo is rejected as soon as it is a few kilobytes too heavy.

For every image, the browser searches the encoder quality step by step and keeps the highest quality that still fits under your target. When lowering the quality alone is not enough, it can scale the image down gradually until it fits, and an image that is already small enough is kept exactly as it is. Each result shows its new size, the percentage saved, its dimensions and the quality used, with a before and after slider to check the details.

You can add up to 30 images at once, save them as JPG or WebP (or keep the original format), cap the width and height, and download one file or everything as a ZIP. Nothing is uploaded: the compression runs entirely in your browser, so your photos stay private on your device.

How to use Compress Image to KB or MB

  1. Pick a target size: 20 KB, 50 KB, 100 KB, 1 MB or type your own value.
  2. Choose the output format: JPG, WebP or the same as the original.
  3. Drop up to 30 images (JPG, PNG, WebP or GIF), or paste one with Ctrl+V.
  4. Check each result with the before and after slider and its final size.
  5. Download a single image, or all of them as a ZIP file.

Frequently asked questions

Click the 100 KB or 50 KB chip (or type any size), then drop your photo. The tool finds the best quality that stays just under that size and shows the final size in bytes before you download it.

Yes, whenever it is possible. A target counts 1 KB as 1,000 bytes, so the file also passes the strictest upload checks. If you turn off "Allow smaller dimensions" and the image is too detailed for the target, the tool returns its smallest version and marks it "Could not reach".

PNG is a lossless format: its size cannot be tuned with a quality setting, so an exact target is impossible. JPG and WebP can be sized precisely. WebP keeps transparency; JPG puts transparent areas on a white background.

Only when it has to. It first lowers the quality; if that is not enough, it scales the image down step by step until it fits. You can turn this off, or set a maximum width and height yourself.

No. The whole compression runs in your browser, so your images never leave your device and the tool works even with private documents.

Yes, up to 30 images per batch. They are processed one at a time to keep your browser fast, and you can download them all together as a ZIP file.
