Compress an image to 50 KB

50 KB is the workhorse Indian form limit

If a portal says “photo should be between 20 KB and 50 KB,” it is not asking you to pick a random quality slider. It is asking for a JPEG the intake server can store millions of times. Phone photos from the last five years start at 2–8 MB. A generic compressor that “saves 70%” can still leave you at 400 KB. The only number that matters is whether the file is at or under 50 KB when the validator runs size.

This page locks the target at 50 KB. The encoder searches quality first so you keep as much detail as the budget allows. Only if the smallest usable quality is still too big does ExactKB shrink the longest side. That avoids the silent downscale some hosted tools apply on every free compress — a behavior that can change a 3.5 × 4.5 cm crop you already framed.

PAN, SSC, and banking photos are not the same crop

PAN windows typically want a front-facing color photograph on a plain background. SSC and IBPS add their own pixel or print-size notes that change by year. Passport Seva has swung between a tight 10–50 KB band and a more generous ceiling near 250 KB. ExactKB’s PAN and SSC chips start at 50 KB with a 400–500 px longest side because that combination usually survives those stacks. They do not crop. If last year’s printout is still on your desk, match that aspect ratio in an editor first.

Signatures on the same applications are almost never 50 KB problems. They are 10–20 KB problems. Compress the portrait here and the signature on the 20 KB page. Mixing them — a tiny face in a signature box, or a huge signature in a photo box — is a common reason humans reject an otherwise valid file size.

A practical 50 KB sequence

1. Crop to the aspect the notice describes. Neutral background. Face in the upper two-thirds if it is a photo field.
2. Drop the file on this page. HEIC and WebP are fine; output should stay JPG unless the form forbids it.
3. Leave the 50 KB target. If you already know they want 600 px on a side, set longest side accordingly.
4. Read the result card. You want ≤ 50 KB and pixels still in the range the notice printed.
5. Download and inspect in Files / Explorer. If the portal counts 1000-byte KB and you sit at 50.2 KiB, uncheck “1024 bytes” and run once more.

Lighting matters more at 50 KB than at 200 KB. Harsh HDR from a phone night mode creates halos that JPEG spends bits on. Daylight on a plain wall is cheaper to encode and looks cleaner after compression. More technique notes: compress without losing quality.

What we will not claim

Hitting 50 KB does not mean the photograph is a valid PAN or exam photo. We are not NSDL, not SSC, and not a studio. Background color, recentness, and glasses rules are yours. If a helpdesk tells you a different kilobyte window this year, believe the helpdesk. Use the custom KB box on the homepage if their number is 40 or 60 instead of 50.

How to hit 50 KB

1. Choose the photo on this page. It stays in this browser tab.
2. Confirm the 50 KB target (already selected on this page).
3. Leave output as JPG unless the form explicitly wants WebP or PNG.
4. If the file is still over after a quality search, set a longest-side cap (1000 or 600 px) and run again.
5. Download the file and check the size in your file manager before you submit.
