Why the caps are so low

These portals are built for surges. When a recruitment notification opens, lakhs of candidates upload documents inside the same few days, and every megabyte is multiplied by that number for storage, backup and bandwidth. Capping each document at a couple of hundred kilobytes is what keeps the site standing.

The numbers cluster because most portals follow the same central guidance, which is why 100 KB, 200 KB, 250 KB and 500 KB turn up again and again across UPSC, SSC, RRB, IBPS, state PSCs, scholarship portals and certificate verification sites.

The step almost everybody skips

Before compressing anything, look at what was actually requested. These forms ask for one document — a mark sheet, a caste certificate, an ID page — and a very large share of oversized uploads are somebody's entire scanned folder attached to a field that wanted a single page.

Extracting the requested page usually solves the problem outright, and it solves it without touching quality. It is also what the reviewing officer wants: one page they can read, not twenty they have to search.

The order to try settings in

• Medium quality first. A single certificate frequently lands under 200 KB here with no visible change at all.
• Greyscale next. A colour scan of a black-and-white document carries three colour channels describing grey paper — dropping them is usually the single biggest saving available, and no portal has ever rejected a document for being greyscale.
• Crop the scanner border. The black edge of a scanner lid is bytes spent describing nothing.
• Low quality last, and only for a page or two, where it stays entirely legible.

What does not help is compressing the same file twice. The second pass re-renders an already-rendered page: you lose clarity and save almost nothing.

The rules that reject a file even at the right size

Size is only one of four checks, and the other three cause at least as many rejections:

• Format. Many portals want the document as a PDF but the photograph and signature as JPG. Uploading the right thing in the wrong container fails silently.
• Encryption. A bank statement that arrived password-protected will be refused at any size, because the portal cannot open it. Remove the password first.
• Dimensions. Some forms specify page size or pixel dimensions for the photograph, separately from the file size.
• Legibility. A document compressed until the text is mush can be rejected on verification, which costs far more time than a second upload.

Photograph and signature are a different problem

The document limits above are not the same as the photograph and signature limits, which are usually much smaller and specified in the notification — commonly tens of kilobytes, with fixed dimensions and a white background.

Those are image requirements rather than PDF ones. Read the exact figures off the notification for the exam you are applying to, because they vary between boards and between years, and a photograph that passed last year may not pass this one.

Doing it without handing over your documents

The files involved here are identity documents: Aadhaar, PAN, mark sheets, caste and domicile certificates, bank statements. They are exactly the documents that should not be uploaded to a site you found through a search result.

Compressing in the browser removes the question. The file is read from your disk by the page you already have open and never leaves your machine — you can prove it by disconnecting from the internet and compressing anyway.
