Compress PDF for Malaysian Government Portal Upload — LHDN, JPA, EPF (2026)

You've filled in the form, scanned all your documents, and then — the portal rejects your file for being too large. This happens to thousands of Malaysians every year on LHDN, JPA, EPF, UPU, and SPA portals. Here's a complete guide to fixing it fast, for free, without uploading your sensitive documents to any server.

File Size Limits by Portal

Malaysian government portals enforce strict upload limits to manage server load. The limits below are based on current portal requirements as of 2026. These limits are per file — not per submission — so a multi-document application may require compressing each file separately.

Most portals share the same 2MB threshold. EPF i-Akaun is stricter for certain document types — when in doubt, compress to under 1MB to be safe across all portals. Portal limits can change without notice; if a file you've submitted before is now rejected, the portal may have tightened its limits.

Why Are My Scanned Documents So Large?

A scanned document at default scanner settings (300 DPI, colour) easily produces a 5–15MB PDF for just a few pages. Understanding why helps you fix it faster — and avoid the problem in future.

• High DPI (dots per inch): 300 DPI is the standard for printing. For screen-only submissions to government portals, 150 DPI produces files that are 75% smaller while remaining perfectly readable. The portal reviewer is reading your document on a screen, not printing it at A3 size.
• Colour scanning: Colour images store three values per pixel (red, green, blue) versus one for grayscale. For official documents like payslips, transcripts, and forms, colour is rarely required — and switching to grayscale cuts file size by 60–70%.
• No compression in the scanner app: Default settings in CamScanner, Adobe Scan, and iPhone Notes prioritise quality over file size. The raw image data is embedded in the PDF with minimal compression applied.
• Multiple pages: A 6-month bank statement scanned at 300 DPI colour can exceed 15MB. Each page adds 1–3MB at high quality settings. A 5-page payslip history can easily reach 8MB before compression.
• Embedded metadata: Scanner apps embed device information, GPS data, and editing history into the PDF. This adds surprisingly little to file size but compounds with other factors.

The practical implication: a document that scans at 8MB can typically be compressed to under 500KB without any visible loss of legibility. The compression headroom is large because the source quality is far higher than needed.

Portal-Specific Tips

LHDN e-Filing (ezHASiL)

LHDN requires supporting documents during tax filing for claims like medical expenses, education fees, donations, and lifestyle purchases. The most commonly rejected files are:

• EA Forms scanned in colour at 300 DPI — typically 3–6MB, compress to under 1.5MB
• Medical receipts with logos and colour headers that inflate file size
• Combined bank statements across multiple months — split into individual months before compressing
• Insurance policy documents that are already-digital PDFs but bloated with embedded fonts

For LHDN, aim for under 1.5MB per file to have a comfortable margin under the 2MB limit. If you're uploading multiple supporting documents (e.g. several months of receipts), compress each one individually rather than merging them first.

UPU / MyGovUC (University Application)

SPM results slips, co-curricular certificates, and personal statements are the most commonly oversized files. Certificates printed in colour on certificate paper and scanned at high DPI are the usual culprits — the colour background and gold borders make these files surprisingly large. Since these documents have no fine print requiring high resolution, 150 DPI black-and-white compression works perfectly and is what portal reviewers expect.

JPA Biasiswa Scholarship Portal

JPA requires income proof, academic transcripts, and supporting letters. Income documents — payslips and bank statements — can get large when covering multiple months. Best practice: upload each document type separately rather than merging everything into one PDF. Compress each file to under 1.5MB. JPA reviewers often need to cross-reference specific pages, and separate files make this easier for them too.

EPF i-Akaun (KWSP)

EPF is one of the stricter portals — some document categories have a 1MB limit per file. Compress your documents to under 800KB when submitting to EPF to be safe. IC copies, bank account documents, and marriage certificates are the most frequent uploads. For IC copies, a simple black-and-white scan at 150 DPI produces a file well under 200KB, which is well within any portal's limit.

SPA Online (Civil Service Application)

SPA requires academic certificates, transcripts, and experience letters. Multi-page transcripts and certificate bundles are common — a full 3-year university transcript can be 10–15 pages and reach 8MB when scanned. Use maximum compression and split certificates from transcripts into separate uploads if the portal allows it. SPA also accepts documents via email in some cases, where attachment limits are typically 10–20MB — compression still helps here.

PTPTN Loan Application

PTPTN commonly requires offer letters, IC copies, and guarantor documents. The guarantor's income documents (payslips, EA form) are often the largest files. Compress each to under 1MB. If a guarantor is submitting on a phone, use ShrinkPDF's mobile-friendly interface — it works on Android and iPhone without installing an app.

Compression by Document Type

Different documents respond differently to compression. Here's what to expect:

Text-heavy documents (letters, forms with typed content) compress significantly better than image-heavy scans. A well-formatted offer letter that is already a digital PDF may only need light compression to stay under 2MB.

Step-by-Step: Compress for Government Portal Upload

Tips Before You Even Scan

If you haven't scanned your documents yet, the right scan settings eliminate the compression step entirely. These settings produce portal-ready files directly from the scanner:

• Use 150 DPI instead of 300 DPI — 150 DPI is sufficient for all Malaysian government portal submissions. Text remains sharp on screen. File size is ~75% smaller than 300 DPI. In CamScanner: Settings → Scan Quality → Standard. In Adobe Scan: this is harder to control, but exporting as "Compressed" helps.
• Scan in black and white (grayscale) — Most Malaysian government documents (payslips, transcripts, letters) do not require colour. Black and white scanning cuts file size by 60–70% compared to colour. In iPhone Notes scanner: use the "Document" option, not "Photo". In CamScanner: colour mode → Grayscale.
• Use Microsoft Lens (free) — Microsoft Lens produces smaller PDFs than most scanner apps by default and has better automatic edge detection. Available on Android and iPhone. Free with no ads.
• Scan individual pages separately if possible — Managing one page at a time makes it easier to verify each scan and control file sizes. Avoid scanning 6-month bank statements as a single session if individual months can be uploaded separately.

Still Too Large After Compression?

For documents that still exceed the portal limit after maximum compression, these are the most effective fallbacks:

• Split the document: Use the ShrinkPDF Split tool to break a multi-page PDF into smaller files. Upload each part separately if the portal allows multiple uploads for the same document category.
• Re-scan at lower settings: If you have the original physical document, re-scan at 100–150 DPI in grayscale. A single A4 page scanned at 150 DPI grayscale is typically 50–150KB — well under any portal's limit.
• Remove unnecessary pages: Use the Reorder tool to delete blank pages, duplicate scans, or summary pages before compressing. Removing even one high-resolution page can make the difference.
• Contact the portal helpdesk: Some portals have an exception process or an email submission alternative for documents that genuinely cannot be compressed further (e.g. a 20-page medical report). LHDN and EPF both have customer service lines where this can be raised.
