Compress JPEG to 100KB

100KB gives a JPEG enough room that compression artefacts stay mild even in photos with fine detail. This compressor starts at a quality level tuned for that budget and shows the live output size as you drag the slider, so you can see the trade-off between file size and sharpness before you download.

How to use this tool

  1. Add your images

    Drop in up to 25 files at once, or tap to choose them. Conversion starts straight away.

  2. Set quality and size

    Lower the quality slider to make files smaller, and cap the largest side if you also want fewer pixels.

  3. Download

    Save each file individually, or use Download all to get the whole batch.

Questions people ask

How much can I compress a JPEG before it looks bad?

For most photographs, quality settings from about 60% down to 40% shrink the file substantially while the image still looks clean at normal viewing size — screens and print both hide a lot. Below that, blocky artefacts start showing up around sharp edges and text.

What is the difference between this and the exact-KB photo tool?

This page batch-compresses at a quality level you control, with the resulting size shown live for each file. The exact-KB photo tool (linked below) instead searches automatically for the setting that lands under 100KB on a single file — pick whichever workflow matches what you are doing.

Are my images uploaded anywhere?

No. The conversion runs in your browser using the Canvas API, and this site has no upload endpoint. Once the page has loaded you can go offline and it still works.

Is there a file size or batch limit?

You can convert 25 images at a time, and file size is limited only by your device's memory. Because there is no server involved, there is no daily cap and no account to create.

Does converting reduce the image quality?

Converting to PNG is lossless. Converting to JPG or WebP re-compresses the picture, so the quality slider controls the trade-off — 82% is a good default that most people cannot distinguish from the original.
