How to get an image under 100 KB

  1. Add the photo or scan

    JPG, PNG, HEIC from an iPhone, WebP or AVIF – the 100 KB limit is already set.

  2. Wait a moment

    KeepPixels finds the highest quality that fits under 100,000 bytes, usually in a second or two.

  3. Download and upload

    The file is ready for your form. Need a different limit? Choose another size above the results.

Your documents stay on your device

The images people squeeze under 100 KB are often the most personal ones – a portrait for an application, a scanned ID, a signed form. KeepPixels never uploads them; the compression happens in your browser.

Getting a photo under 100 KB without ruining it

A 100 KB limit is common on job and university application portals and on online forms where you upload a photo or a scanned page. Modern phone photos are often 3–6 MB, so they have to shrink by 95% or more.

What fits in 100 KB

  • A portrait photo with a plain background, at a size that looks sharp on screen.
  • A scanned A4 page with text, in good legibility.
  • Not a full-resolution 12-megapixel photo – that always needs to be scaled down.

Tips for application photos

  1. Crop to the requested shape first (for example 3:4 for a portrait). Every pixel you remove leaves more room for the face.
  2. Use a calm, even background. Busy backgrounds cost a lot of kilobytes.
  3. Don’t enlarge small images. It adds size without adding detail.

For any other limit, use compress to an exact size.

Frequently asked questions

The portal still rejects my file. Why?

Check the other requirements – many forms also ask for a specific format (usually JPG), a minimum width and height, or a set aspect ratio. Our result is always a JPG under 100,000 bytes, which also passes forms that count 1 KB as 1,024 bytes.

Can I get under 100 KB without losing quality?

Some quality is always traded for size, but for a portrait or a document page the loss is usually invisible. KeepPixels lowers the quality only as far as needed and shrinks the image only when quality alone isn't enough.

How big will the image be in pixels?

It depends on the content. A typical portrait photo ends up somewhere around 800 to 1,200 pixels on the long side; a simple document page can stay larger.

Does it work with iPhone photos?

Yes. HEIC photos are converted to JPG and compressed in one step, and the orientation is correct.

Can I compress a PDF to 100 KB here?

No, KeepPixels handles images only. If your document is a PDF, export the page as an image first.
