Fills transparent areas (JPG has no transparency).

The size is preset to 100 KB in JPG. The tool keeps the best quality that fits, and only makes the image smaller in pixels if it has to. Images already under the limit are left untouched.

Images are resized locally in your browser. Nothing is uploaded or stored.

When 100 KB Is the Right Size

100 KB is a sweet spot: small enough for upload forms, email attachments and fast-loading web pages, yet large enough that a photo still looks good on a full phone screen. It is also a common limit for document scans on application portals.

How to Resize Images to 100 KB

  1. Drop one or more images into the box above.
  2. The target is 100 KB and the output is JPG. Pick a different size with the buttons if you need to.
  3. Press Resize Images.
  4. Download each image, or use Download All (ZIP) for the whole batch.

Tips for Documents and Websites

  • Scanned documents: crop away the empty border first. Need one file? Combine the pages with JPG / PNG to PDF.
  • Websites: for even smaller files at the same quality, try WebP, which every modern browser supports.
  • Screenshots and text: keep enough pixels for the text to stay readable; the tool only reduces pixels when quality alone can't reach 100 KB.

Frequently Asked Questions (FAQs)

How do I reduce an image to 100 KB?

Drop the image here and press Resize Images. The target is preset to 100 KB, and the tool keeps the highest quality that fits.

Can I resize many photos to 100 KB at once?

Yes. Drop them all together, press Resize Images, and download them as one ZIP file.

Will a 100 KB photo look good?

Usually yes. 100 KB is enough for a sharp photo on a phone screen or a web page. Very large or detailed photos may be made a little smaller in pixels to fit.

Which format should I choose?

JPG works everywhere and is the default here. WebP gives better quality at the same size if the site accepts it.

Are my photos uploaded to a server?

No. The photo is compressed inside your browser on your own device. It is never uploaded, so the tool is safe for ID photos and personal documents.
