Compressing a PDF for IRCC: how to use the free tool, step by step
You scanned everything, merged it all into one PDF, and the IRCC portal turns the file away. It is the most ordinary hitch of the whole submission, and it stops plenty of people on a Sunday night. The reason fits in one sentence: IRCC caps every uploaded document at 4 MB. A bundle of scanned documents clears that bar without trying.
The tool called Compress a PDF lives inside the Prepare my file page. Open /en/check-list.html#pdf and the right tab opens by itself. It is free, no account is needed, and it works just as well from a phone.
Your document goes nowhere
That is the first point, and it matters more than the rest. The page says it plainly: everything happens inside your browser, nothing is sent. Your passport, your birth certificate, your bank statements stay on your device. You can even cut your connection once the page has loaded.
The steps, in order
Tap Choose my PDFs, or drag your files into the frame. You may drop several at once.
The tool reads the document and shows its name, its number of pages and its weight, with a clear verdict: under the 4 MB bar, or still above it.
Then it offers three levels: light, medium, high. Above all, it shows the estimated size for each one before you choose. So you can see in advance which level is enough. Always take the lightest one that passes: the less you compress, the sharper the document stays.
Tap the button on the level you picked. A few seconds later the tool announces the size obtained, the percentage saved, and offers to save the file. On a recent browser a real Save as window opens and you choose the folder; elsewhere the file lands in your Downloads folder. It keeps the original name followed by compressed, so you never mix the two up.
Tempted by another level? Just tap its card again, no need to start over.
What the tool refuses to do
It never compresses to the point of making a document unreadable. The high level is a floor: there is no stronger setting. If even that level stays above 4 MB, the tool says so and advises splitting the bundle into two uploads — identity and studies on one side, work and finances on the other — then compressing each. That is the right answer: a page an officer cannot read may cost you the document, and the points with it.
Another nicety: it recognises pages that are already clean — a typed letter, a certificate born as a PDF — and leaves them untouched. It only lightens scans and photos. If your document is clean from end to end, it tells you so and advises keeping it as it is: compressing would damage the text for almost no gain.
Several files at once
Drop the whole batch, pick a level, and the tool processes them one after another. Each one gets its own download button. If your browser can open a folder picker, a single button writes the whole batch to the same place. You will be glad of it the night before a submission, with eight documents still to go.
Read it again before sending
Open the compressed file and really look at it. You are the one who validates, not the site. Aim at the small print: passport number, dates, amounts on a statement, an employer’s stamp, a handwritten note. If a line goes soft, move up one level and start again.
And keep your originals somewhere else. Compression cannot be undone: the lighter file is a copy for IRCC, not your archive.
