When do you need a 100KB image?

100KB is the everyday sweet spot for online forms: big enough that a photo still looks good, small enough for almost every upload limit. This page is preset to 100KB, so all you have to do is drop your files in.

Step-by-step guides for this size

How to compress an image to 100KB

  1. 1. Add your images

    Drag and drop JPG, PNG, WEBP, HEIC, GIF, BMP or AVIF files — or select them from your device. Nothing is uploaded.

  2. 2. Set the target size

    Pick 100KB or type your own limit. Advanced options let you set dimensions, format and quality priority.

  3. 3. Download the result

    Every file shows its before and after size. Download them individually or grab a ZIP of the whole batch.

Why this compressor actually reaches your limit

Exact target file size

Say “200KB” instead of guessing a quality percentage. A binary search finds the highest quality that still fits your limit.

Batch compression

Add up to 30 images, optimize them in one run, and download everything as a single ZIP archive.

100% private

Images are decoded and re-encoded on your own device with the Canvas API. Nothing is uploaded to any server.

Automatic resizing

When quality reduction alone cannot reach the target, pixel dimensions are reduced step by step until it fits.

Need a different file size?

Every size below uses the same optimizer with a different preset target.

Your images never leave your device

Compression runs in a Web Worker inside your browser using the HTML5 Canvas API. There is no upload step, no temporary storage and no server-side copy — which is exactly why passport photos, ID scans and exam documents are safe to process here. Read the privacy policy.

Frequently asked questions

Does compressing to 100KB reduce quality?

Some data is always discarded when a JPEG gets smaller, but at 100KB the loss is usually invisible at normal viewing size. The tool keeps the highest quality level that still fits the limit instead of over-compressing.

Can I compress many photos to 100KB at once?

Yes. Add up to 30 images at a time and download them individually or as a single ZIP archive.
