How It Works

  1. 1

    Upload the image you want to shrink

    Drop a JPG, PNG, or WebP file. Most phone photos start at 2–8 MB; they'll compress to under 100KB in seconds.

  2. 2

    Adjust the quality slider until the size is under 100KB

    Watch the live file-size counter. For most photos, setting quality to 60–70% hits the 100KB target without visible degradation.

  3. 3

    Download and verify the size

    Click Download. The saved file will be at the exact size shown in the preview — usually under 100KB.

Frequently Asked Questions

Why does my passport photo need to be under 100KB?+
Government portals impose strict upload limits to reduce server load and standardize document handling. The 100KB limit is common for visa applications, ID forms, and civil service portals.
Will compressing to 100KB make my photo unusable?+
For standard portrait photos (not screenshots or graphics), 100KB is sufficient for most web forms. The tool maximizes quality within that constraint using progressive JPEG encoding.
Can I compress a PNG to 100KB?+
Yes. PNG compression is lossless, so the tool re-encodes as JPEG when targeting very small sizes. You can choose to keep PNG format or switch to JPEG in the format selector.
