Passport Size Photo under 100KB: How to Resize Online

By EasyImageCR • 2025-12-08 • ⏱️ 4 min read

The Problem: Many online application forms (for exams, jobs, or visas) have a strict limit: "Image size must be under 100KB" (or sometimes between 50KB and 100KB). If your phone photo is 2MB, it will be rejected.

Reducing a high-quality photo to 100KB without making it blurry can be tricky. If you compress it too much, faces become unrecognizable. If you don't compress it enough, the form rejects it.

Why 100KB?

100KB is a "sweet spot" for many government and official portals. It allows for enough detail to verify your identity (unlike 20KB images which can be pixelated) but is still small enough to not overload their servers.

The Solution: "Target Size" Compression

Instead of guessing with "70% quality" or "Medium quality," you should use a tool that lets you specify the exact file size you need.

✅ How to Compress to Under 100KB (Step-by-Step)

Use our free tool EasyImageCR.in. It works locally in your browser for maximum privacy.

  1. Upload Your Photo: Drag and drop your passport photo or document.
  2. Select Compression Mode: Choose "Target Size (KB)" from the dropdown.
  3. Enter Limit: Type 100 (or 95 to be safe) in the input box.
  4. Check Format: Ensure "JPG" is selected.
  5. Click Resize & Download: The tool will automatically calculate the best quality settings to get you a file just under 100KB.

Common File Size Requirements

If you need a different size (like 50KB), just change the number in the "Target Size" box. It's that easy.
