Compress Image to 100 KB

How to use

This page takes any JPG, PNG or WebP and gives you a copy under 100 KB, made on your device, for job applications, exam and visa portals, marketplaces and forms that refuse bigger files.

1. Add the images: drag them in, pick them, or paste a screenshot. Up to 50 go in together.
2. The compression is set to Target size with 100 in the box. Change the number if your form says 150 or 80.
3. Wait a moment per image. The page tries a series of quality levels and keeps the best one that lands under 100 KB. When even the lowest acceptable quality is too big, it reduces the width and height a little and tries again.
4. Read the note in each row: it says the size the file came out at, and whether it was shrunk in pixels. A file that was already under 100 KB is handed back as it was.
5. Drag the split in the comparison to see what changed, then download one file or all of them in a ZIP.

What fits in 100 KB? A typical photo at 1,200 pixels wide, at a quality most people can't tell from the original. Screenshots with large flat areas compress far better than that; a detailed photo with foliage or fabric compresses worse and may need to be a little smaller in pixels.

A JPG stays a JPG and a PNG a PNG. For a photo saved as PNG, which is often a megabyte or more, convert it to JPG with the image converter first: it will shrink far more at the same quality.

Compressed copies carry no camera details or location; the picture is turned upright before saving, so it looks the same everywhere.

Frequently asked questions

Why 100 KB? Where does that limit come from?

Many government, university and recruitment portals cap uploads at 100 KB to keep their storage small and their pages quick. Marketplaces and forum avatars often use the same figure. This page meets it without you having to guess at quality settings.

Will the picture still look sharp under 100 KB?

For a photo up to about 1,200 pixels wide, yes: the page keeps the highest quality that fits, and JPGs are saved with MozJPEG, which packs more detail into each kilobyte than most programs. Very large or very detailed photos are reduced in pixels a little, which you can see in the row and the comparison.

Can I get a PNG under 100 KB too?

Yes. A PNG is reduced to fewer colours first, which is what makes screenshots and graphics small, and only then made smaller in pixels. A PNG that is really a photo compresses poorly, so turn it into a JPG first if the form allows JPG.
