How to Compress JPEG for Passport Photo Uploads

Updated August 15, 2026 · 8 min read

Getting a JPEG ready for passport photo uploads is mostly about two numbers: pixel width and file size. Online photo uploads for official documents usually state a maximum file size and pixel range, and files outside it get rejected.

Recommended settings for passport photo uploads

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 600 px on the long edge
Quality70
File size100 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

How to Compress JPEG

Start by resizing. A photo straight from a phone is often 4000 pixels wide, while passport photo uploads rarely benefits from more than about 600 pixels. Halving the width cuts the pixel count to a quarter, which shrinks the file far more than any quality slider.

Then set quality. For passport photo uploads, a quality around 70 keeps edges and skin tones natural while removing detail your eye will not miss. If you have a hard cap, type it into the target size box and let the compressor search for the highest quality that fits under 100 KB.

Quick tips

  • Write a size limit slightly below the stated maximum to leave a margin.
  • Process private images locally rather than uploading them to unknown servers.
  • Crop out distractions so pixels go to the subject.
  • Use WebP where it is supported and you control the page.
