How to compress image to 100kb

To compress an image to 100kb, drop it in the box above: the target is already set, so the tool finds the best quality that fits and you just download the result. 100 KB is roomy enough for a clear photo up to about 1000 pixels wide, which is why it is a favourite limit for job portals, university applications and bank KYC uploads. The compressor tries the highest quality first and only lowers it as far as needed to get under 100 KB.

About the Image Compressor

Large photos slow down websites, bounce off email size limits and get rejected by online application forms. This compressor re-encodes JPG, PNG and WebP images in your browser so you can pick the balance between file size and sharpness yourself, or simply type a target such as 100 KB and let it find the best quality that fits.

When to use it

  • Shrinking a passport photo or CNIC scan to the 50–200 KB limit many government and university portals require
  • Making product photos load faster on a shop or WordPress site
  • Sending a batch of holiday pictures over WhatsApp or email without hitting attachment limits
  • Preparing blog images so Google’s page-speed checks stop flagging them

Tips for the best results

  • WebP usually gives the smallest file at the same visual quality; use it for websites, but keep JPG for forms that only accept .jpg
  • If a target size can’t be reached, set a max width (1600 px is plenty for most screens) and try again
  • PNG is lossless, so compressing it changes little — convert photos to JPG or WebP for big savings

How to use the Image Compressor

  1. Open the Image Compressor and drop your image (or tap to choose one).
  2. Adjust the options — the preview updates instantly.
  3. Press Download to save the result. Nothing is uploaded.

Image Compressor FAQ

How do I reduce a 2 MB photo to 100 KB?

Drop it here — the compressor lowers the quality and, if needed, the width until it is under 100 KB. A 2 MB phone photo usually ends up around 1000–1200 pixels wide.

Will the photo still be clear enough for a form?

Yes. 100 KB is plenty for a face photo or a document page to be read on screen. For printing, keep the original as well.

Can I compress a screenshot to 100 KB?

Screenshots are usually PNG. Leave the format as JPG here and the screenshot will compress well, though very small text may soften slightly.

Which format gives the smallest file?

WebP is usually the smallest at the same visual quality, followed by JPG. PNG is lossless, so it stays large for photos. Use JPG if a form only accepts .jpg files.

Will compressing reduce the quality of my photo?

A little, but at quality 70–85% most people cannot see the difference on a screen. Very low targets such as 20 KB will show some blur, so pair them with a smaller width.

Is the Image Compressor free?

Yes. The Image Compressor is completely free with no sign-up, no daily limit and no watermark.

Is it safe to use the Image Compressor with private files?

Yes. The Image Compressor runs entirely inside your web browser, so your files and text are never uploaded to any server.
