Compress Image to 100KB

Upload a photo and this tool creates a copy that is 100 KB or less, ready for application forms and portals with a strict upload limit. It lowers the encoding quality first and reduces the width and height only when quality alone cannot reach the limit, all inside your browser.

Your images are processed locally in your browser. They are not uploaded to Rabetly.

How to compress an image to 100 KB

  1. Click to upload or drop an image (JPEG, PNG, WebP, GIF or HEIC, up to 35 MB).
  2. Check the line that reads Target: 100.0 KB or less, and choose jpeg under Output format unless you need transparency.
  3. Click Process image; the tool tries several quality levels and, only if needed, smaller dimensions until the file fits.
  4. Confirm the Result is 100.0 KB or less message, then review the File size and Dimensions.
  5. Click Download result and attach the file to your form.

When you need an image under 100 KB

  • A student uploading a personal photo to a university admission portal that rejects files over 100 KB.
  • A job seeker attaching a passport-style photo to a government or recruitment e-service.
  • An applicant submitting a scanned ID card or signature to a visa or exam registration form.
  • An employee adding a profile picture to an HR system with a 100 KB cap.

How this tool works

This page aims for the advertised maximum, not a padded exact size. It searches quality first and only reduces dimensions if its quality safeguard cannot meet the target.

Example

Upload an image for a 200 KB upload limit; the result will be 200 KB or less when it can be reached without crossing the minimum safeguards.

Compress Image to 100KB: frequently asked questions

Will the file be exactly 100 KB?

No. The tool guarantees 100 KB or less, not an exact size, and it never pads a file with empty data to reach a number. It keeps the highest quality it finds that still fits, so small images can come out well under the limit.

Is 100 KB here 100,000 or 102,400 bytes?

102,400 bytes. The tool counts 1 KB as 1,024 bytes, so if a form defines 100 KB as 100,000 bytes and rejects the file, try the 50 KB compressor instead.

What if the image cannot get under 100 KB?

You get a message instead of a file that is too large. The tool will not go below 45% quality and shrinks dimensions only in limited steps, never below 320 pixels on the long side; PNG output ignores quality, so choose jpeg or webp, or crop or resize the image first.

Is it safe to compress an ID or passport photo here?

The photo is processed locally in your browser and is not uploaded to our servers. The output is re-encoded from the pixels, so it normally carries no EXIF data such as GPS location.
