Everything we know about getting images through picky upload forms — written for humans, not for search engines (though they’re welcome too).
How image compression actually works (and how we hit exact KB targets)
What JPEG quality really does, why the same setting gives different file sizes for different photos, and the binary-search trick that lands a file just under any KB limit.
JPEG vs PNG vs WebP: which format for which upload
A practical decision guide to the three image formats that matter for uploads — how each one compresses, what each is best at, and why government portals only take JPEG.
Photo size requirements: SSC, UPSC, PAN, Passport Seva & DV Lottery (2026)
The photo and signature upload specifications for major government portals in one table — file size, dimensions, format and content rules, with presets that match each one.

The photos you compress for forms are your face, your signature and your documents. How to tell whether an online tool uploads them — and how to verify a local-only claim in two minutes.

Every common reason government and exam portals reject photo uploads — file too large, wrong dimensions, wrong format, background, printed date — with the specific fix for each.
