Compress a PDF to Fit a Portal’s Size Limit

Read the notice, not a coaching site’s summary of it

Most upload requirements name a floor as well as a ceiling. The NEET UG 2026 bulletin asks for a certificate “between 50 kb to 300 kb”, and the portal turns down a file under the floor exactly as firmly as one over it — which is why a tool that models the target as an upper bound alone can hand you a file that fails with no explanation attached.

Two PDF presets ship with the app, and each shows its source on screen: NTA NEET UG at 50–300 KB, and the Income Tax e-filing portal at up to 5 MB, both read from the authority’s own publication. Anything we could only trace to a coaching summary is labelled as such beside the number. Check the current notice yourself anyway, including the file type — a PDF preset will not rescue you from a portal that wanted a JPEG.

Pick a target, then read the sentence that comes back

Open the document, choose Compress, and pick a target. The plain ceilings run from under 100 KB to under 5 MB; the portal presets sit below them with their bands shown. Then choose where the output goes — compression writes a new file, so it is not one of the in-session edits you can undo.

Now read the result rather than the file size. “Already inside 50–300 KB. Left untouched” means it fits and re-compressing would lose quality for nothing. “Below the 50 KB floor” means compression is the wrong direction entirely. And when even the hardest acceptable setting stays over the ceiling, you are told the smallest size the pages survive at, instead of being handed something unreadable at the number you asked for.

If it barely shrank, it was never going to

Before it starts, Creasepoint looks at what is actually in the document, and warns you when the answer is text and vectors. A Word export, a bank statement, an e-filing acknowledgement — there is nothing in those to re-encode, and you should expect a few percent at best. That is the honest answer to “why is my 1.4 MB file still 1.3 MB”. Compression squeezes images. It cannot squeeze a font.

When that is the problem, the fix is fewer pages rather than harder compression: Extract pages builds a new PDF from the ones the recipient asked for. Then open the output, check the scan is still legible and the seal or signature still readable, and make sure you attach the compressed file and not the original sitting beside it under a similar name.

A whole folder of them

The Batch tool runs one operation over every PDF in a folder and writes the results into a folder you choose, each file handled in its own confined worker. “Compress to under 300 KB” is the first of six jobs; the rest are English OCR, page numbers, a DRAFT watermark, Word text export and form flattening.

Note that batch offers that one compression target and not the full preset list, so if you need the 50–300 KB band across forty files, the command line is the route. Either way, read the per-file results. A run that finished is not a run where every file worked, and the one that failed is usually the one you needed.
