Every figure below is taken from the commission's own notification or portal manual, and each row links to a dedicated tool that also handles that body's other rules (filename, ink colour, a minimum size that a small file cannot reach). Where a commission does not state a figure, the table says so rather than guessing.

Portals do not agree on whether a kilobyte is 1,000 or 1,024 bytes. This tool keeps the file below your maximum × 1,000 bytes and above your minimum × 1,024 bytes, so a file it calls “10–20 KB” passes under either rule.
A few commissions ask for a thumb impression as well: OPSC (150 × 200 px, under 150 KB), RPSC (left thumb, 20–50 KB) and IBPS PO (left thumb, 20–50 KB). Use those pages; each follows its notification's rules.
Add your scan, press the 10–20 KB button, and enter the pixel size if your form states one. The tool crops to that shape and adjusts JPEG quality until the file lands between 10 and 20 KB.
A small, high-contrast signature compresses to very few bytes. Use a larger pixel size if the form allows it, or scan in greyscale instead of pure black and white; both add the detail a minimum needs.
Each commission sets its own. The table on this page lists the figures from each body's official notification, with a link to the dedicated tool.
No. The crop and compression run in your browser on your own device.
