How to Compress a PDF to Under 2 MB for UK Visa (VFS Global)

TL;DR

UK visa applications submitted through VFS Global enforce a 2 MB per-file cap. Our browser-based Compressor hits that target for most PDFs in seconds — structural pass first, then progressive re-rendering only if needed. Your file never leaves your device.

How to compress a PDF to 2 MB

1. Open the Compressor — go to findmyvisa.co.uk/compress.
2. Drop your PDF in — single file, up to 100 MB. The file is loaded into your browser's memory, never uploaded.
3. Pick "2 MB" — radio button labelled "2 MB · VFS Global". The compressor knows exactly what target to hit.
4. Click "Compress to 2 MB" — structural optimisation runs first; if needed, the file is re-rendered at progressively lower DPI until it fits.
5. Download and upload — save the compressed PDF and upload through VFS Global's portal as instructed.

What happens during compression

Stage 1: structural optimisation

PDFs ship with bloat — unused fonts, duplicated streams, uncompressed metadata. The first pass re-saves the file with object streams and removes duplicates. Saves 5-20% on most files with zero quality loss.

If your file is now under 2 MB, you're done.

Stage 2: re-rendering (if needed)

If structural optimisation isn't enough, we render each page to a canvas at progressively lower DPI (200 → 64) and JPEG quality (85% → 45%) until the result fits. The output is still a valid PDF and looks identical when uploaded — but text becomes a flat image, no longer searchable.

The DPI/quality combination is chosen automatically — we never go below what's legible.

Tips for hitting 2 MB cleanly

Pre-compress images before bundling

If your bundle contains high-resolution photo evidence (passport scans at 600 DPI, relationship-evidence photos at 12 MP), compress them individually before adding to the bundle:

• Scan documents at 300 DPI (not 600+) — photo-quality not needed for visa documents
• Convert phone photos to 1200x1600 max resolution
• Save as JPG with 80-85% quality

Greyscale where possible

Bank statements, employer letters and contracts compress dramatically when scanned in greyscale rather than colour. Most scanners and phone document apps have a greyscale option. UKVI accepts greyscale for non-photo documents.

Skip what UKVI didn't ask for

Many applicants bundle every piece of paper they have. UKVI wants the documents listed in the official guidance — not extra "supporting" letters from family, photos from your wedding, or a 50-page CV. A focused 1.5 MB bundle is better than a padded 5 MB one.

Common refusal causes related to file size

• Silent VFS upload failure — the file simply doesn't attach; you submit thinking it did, and the application is refused for missing evidence
• Caseworker can't open the file — happens if the compressor went too aggressive (very low DPI on important text)
• Upload aborts mid-way — partial uploads are common with files at the limit; well-under-target is more reliable than right-at-limit

Why our compressor specifically

Generic compressors (ilovepdf, Smallpdf) offer "low / medium / high" settings. They don't know about the VFS 2 MB cap — you have to test which setting works.

We size for the actual portal limits. And because the compression runs in your browser, you can compress sensitive documents (passport scans, bank statements, payslips) without trusting a third-party service with them.
