Compress an image to 100 KB

The most common upload limit on job portals, forms and websites. Bring any photo under 100 KB while keeping it crisp.

Target: under 100 KB (JPG) — set for you

Your photos never leave your device · up to 30 at once · 1 KB = 1,000 bytes, so the file passes however the site counts

Advanced settings: format, quality, width, size

Chosen automatically to reach the target size.

How to compress a photo to 100 KB

  1. The target is already set to “Under 100 KB” and JPG output.
  2. Select or drop your images. They are processed on your device — nothing is uploaded.
  3. Check the before-and-after size and download. Your original files are not changed.

Common uses for 100 KB images

  • Job-portal and CV photos
  • Website and marketplace listing images
  • Email signatures and newsletters

Tips for the best result

  • 100 KB is usually enough for a photo around 1200–1600 px wide at good quality.
  • If the photo has fine detail (foliage, crowds), reduce the width before lowering quality.
  • For a website, consider WebP: at the same size it typically keeps more detail than JPG.

What we measured at 100 KB

We ran four test images through this page on 6 October 2026, in Chrome, with its default settings (JPG, at most 1600 px wide). Sizes are in KB of 1,000 bytes.

Three of the four samples fit under 100 KB at their full width: the two simpler photos at 1600 px, and the screenshot at its original 1366×900. Only the detailed flower photo was reduced, to 1120 px. That makes 100 KB the smallest of these targets where most images keep their size.

Your own photos will differ: detail, noise and text all take more bytes than smooth areas.

Will my photo still look good at 100 KB?

For most uses, yes. A 100 KB JPG is a fraction of a phone photo's size but still large enough to look sharp on a laptop screen. The bigger danger is blurring from over-compressing a very large image — which is why the tool reduces dimensions first when it needs to.

Batch compression

You can drop up to 30 images at once; each is compressed to the target separately and downloads with “-compressed” added to its name, so your originals are never overwritten.

Need to share it rather than upload it somewhere? Turn it into a link instead.

Questions and answers

Will 100 KB look sharp on screen?

For most photos, yes. Two of our three test photos stayed 1600 px wide under 100 KB, which fills most laptop screens. Very detailed scenes end up smaller, around 1100 px in our test, which still looks clean at normal viewing size.

Should I use JPG or WebP?

Use JPG for forms and portals, because every site accepts it. Use WebP for your own website: at the same file size it usually keeps more detail. The target setting works for both.

Why is my screenshot not resized?

Screenshots of web pages compress well because large areas are flat colour. Our 1366×900 screenshot reached 98.8 KB without losing a pixel. Screenshots full of photos or gradients behave more like photos.

My photo is already under 100 KB. Will it get bigger?

The tool re-saves the image at a quality that fits under the target, so a small file can come out a little larger or smaller. The results show both sizes; if the new one is not smaller, keep your original.

Does it work on a phone?

Yes. Tap the upload area to choose photos from your gallery. Everything runs in the phone’s browser; the photos are not uploaded.
