How to Reduce Image Size for Passport Applications

By FlowVid Team·Last updated May 2, 2026

Passport, visa and government portals are famous for their strict photo requirements. Beyond the right dimensions and background, almost all of them cap the file size — commonly at 20KB, 50KB or 100KB. Upload anything larger and the form simply rejects it. Here's how to get your photo within the limit without it turning into a blurry mess.

Step 1: Start with the right photo

Use a clear, front-facing photo with a plain light background. Crop it to a head-and-shoulders composition before you compress — a tightly cropped photo has less detail to store, so it compresses to a smaller size at higher quality.

Step 2: Convert to JPG

Almost every application portal expects a JPG (sometimes called JPEG). JPG is a compressed photo format, which makes hitting a small target size far easier than with a PNG. If your photo is a PNG or HEIC, convert it to JPG first using our free Image to JPG converter.

Step 3: Compress to the required size

Now reduce the file to the exact limit. Instead of guessing quality settings, use a target-size tool that automatically finds the highest quality that still fits. For a 20KB limit use the Reduce Image to 20KB tool; for 50KB use Reduce Image to 50KB. Both are free, and we never store your ID photo — it’s discarded the moment you’re done.

Common size requirements

  • Passport photos: often 20KB–50KB
  • Visa applications: frequently under 50KB or 100KB
  • Competitive exams (UPSC, SSC, banking): photo 20KB–50KB, signature 10KB–20KB
  • Job portals: usually under 100KB

Tips to keep quality high

  1. Crop tightly before compressing.
  2. Always export as JPG, never PNG, for photos.
  3. Use the largest size the form allows — pick 50KB over 20KB when you can.
  4. Keep the original photo so you can re-compress to a different target later.

That's it. With the right format and a target-size compressor you can meet any portal's limit in under a minute.
