Compress Image to 100KB — Free, Fast & Private

Many online portals, government forms, and job applications require images under 100KB. Phone cameras produce photos of 3-10MB, making this limit difficult to meet without the right tool. MiniPx makes it simple.

The most effective approach combines compression with resizing. Set max width to 800px, choose JPEG format, and use the Tiny preset. This typically produces files of 30-80KB from any source photo.

MiniPx shows the compressed size next to each image so you can verify it meets the requirement before downloading. If still over 100KB, try reducing max width further or cropping the image first.

How it works

  1. Upload your image: Add the photo you need to compress to under 100KB.
  2. Set Tiny preset + JPEG: Maximum compression with JPEG format produces the smallest files.
  3. Set max width to 800px: Reducing dimensions is key to hitting strict size limits.
  4. Check size and download: Verify the compressed size shown, then download.

Frequently asked questions

How do I get an image under 100KB?
Use JPEG format with Tiny preset and 800px max width. This typically produces files of 30-80KB. Check the size shown after compression.
Will the image look blurry at 100KB?
At 800px width, a 100KB JPEG looks clear enough for form uploads and ID photos. For higher quality within 100KB, try Smart preset first.
What if my image is still over 100KB?
Reduce max width to 640px or crop the image to show only the required area before uploading to MiniPx.
Can I compress signatures to under 100KB?
Yes easily. Signature images typically compress to 10-30KB in JPEG format even at Smart quality.
