Compress PDF for NSP Scholarship Upload
The National Scholarship Portal caps most supporting documents at around 200 KB.
Before you use this: This tool rasterises your PDF — text becomes part of an image and stops being selectable or searchable. For a résumé this matters: applicant tracking systems read the text. If your file is only slightly over the limit, re-export from your word processor at lower image quality instead.

NSP is one of the tightest document portals in common use. Scan in greyscale at 200 dpi from the start rather than compressing a large colour scan afterwards.

Why uploads get rejected
Meeting the size is only part of it. These are the failures that actually come up:
- A colour scan of a black-and-white certificate.
- A photograph of a document taken with a phone at full resolution.
- The document became illegible after compression — rescan at lower resolution instead.
How it works
Each page is rendered with pdf.js and re-encoded as a JPEG, then the pages are reassembled into a new PDF with pdf-lib. A binary search over image quality — and, if needed, render resolution — lands the result under your target.
The trade-off, stated plainly: this rasterises the document. Text becomes part of an image, so it is no longer selectable, searchable, or readable by automated systems. That is how most "compress to X KB" services work, and it is the only way to hit a hard size target in a browser — but it is a real cost. If you need the text to stay live, use a smaller scan resolution instead of compressing afterwards.

Frequently asked questions
Why is my file too large in the first place?
Almost always an embedded image at print resolution — a headshot, a logo, or a scanned page. Text itself takes very little space; a text-only PDF is usually well under 300 KB.
Will this affect how systems read my document?
Yes, and it matters for résumés specifically. Rasterising removes the text layer, and applicant tracking systems parse that text. If you are close to the limit, re-exporting with lower image quality preserves the text and is the better fix.
Should I keep the original?
Always. Keep a full-quality version for printing and for sending directly to a person, and use the compressed one only where a portal forces it.
Are my files uploaded to a server?
No. Everything runs inside your browser on your own device. Your file is never transmitted and never stored by us. You can confirm this by opening your browser’s Network tab while you use the tool — you will see no upload request.
Is there a limit on how many files I can process?
No. There is no daily cap, no account, and no watermark. Because the work happens on your device rather than our servers, there is nothing for us to ration.
Is this tool really free?
Yes — no account, no trial, no watermark, and no cap on usage. It runs on your own device rather than our servers, so there is no cost for us to pass on.
Does it work on mobile?
Yes. The interface adapts to phone and tablet screens, and everything runs in the browser, so there is no app to install.
