How to compress an image to 100 KB

  1. 1

    Add your photo

    Drop a file on the tool, choose one from your device or paste it from the clipboard.

  2. 2

    Keep the size at 100 KB

    The tool starts at 100 KB and compresses the photo at once. Type another size if your form asks for one.

  3. 3

    Check and download

    Compare it with the original, then download the file. Its exact size is shown to the byte.

What 100 KB is enough for

In 100 KB a photo stays clear at a size fit for most forms and web pages. Many application forms ask for photos of up to 100 KB, so this is one of the most common limits.

Check the pixels the form asks for

Some forms set both a file size and dimensions in pixels. Crop or resize the photo to the dimensions first, then compress it here: the size in KB is the last step.

Quality first, then pixels

A JPG or WebP file gets smaller in two ways: a lower quality, which drops fine detail the eye hardly sees, or fewer pixels. The tool lowers the quality first, only as far as the photo still looks good, and then makes the photo smaller. Tick “Keep the dimensions” when the size in pixels must stay; then only the quality goes down.

When the photo itself is the problem

Compression makes a photo lighter, not better: it cannot fix a blurry, dark or badly framed picture. If the photo is for a CV, a profile or an application and you have no good one, a professional headshot made from a few selfies gives you one.

Questions about compressing to 100 KB

How do I compress an image to 100 KB?

Add the photo and download it: the tool starts at 100 KB. It finds the highest quality that fits and makes the photo smaller only if it must.

How do I reduce a photo to 100 KB on a phone?

Open this page in the phone browser, choose the photo from your gallery and download the result. It works the same as on a computer.

Why is the file a little under the size I chose?

Sites count a kilobyte as 1000 or as 1024 bytes. The tool counts 1000, the stricter of the two, so the file fits either way. It keeps the best quality that fits, which lands just under the limit.

Will compressing make my photo look worse?

The smaller the file, the more detail goes. The tool keeps the highest quality that fits and makes the photo smaller before the quality gets low. Click “Show original” to compare before you download.

Is my photo uploaded anywhere?

No. The photo is compressed by your browser, on your device. It is not sent to PicSuit or to anyone else.
