How to combine PDFs for IRCC in 3 steps

  1. 1

    Select every PDF that belongs to the same IRCC field, such as a reference letter, a contract and pay stubs.

  2. 2

    Drag them into the order an officer should read them, most important document first, and remove any extras.

  3. 3

    Press “Process” and download one PDF. Then check its size against your account's limit before uploading.

Your files never leave your device

This tool runs entirely inside your browser. The file is never uploaded to any server: it is read, processed and downloaded on your own device. When you close or reload the page, it is gone from memory.

Why IRCC needs one file per field

According to the official IRCC Help Centre, checked in September 2026, you can only upload one file per field. If you upload a second file into the same field, only the last one is kept, and the earlier one is replaced without much warning. IRCC's own suggestion is to combine your PDFs into a single PDF.

That affects fields like proof of employment, proof of funds, police certificates with translations and passport pages, where you usually have several separate documents.

Plan the order before merging

Write down what goes into the field and in what order. Put the main document first, for example the reference letter before the pay stubs, and keep each translation right after the document it translates. Turn sideways pages upright with “Rotate PDF” before merging.

Paper documents can go through “Scan to PDF” on your phone first, and existing photos through “JPG to PDF”. Then merge everything here.

Merging doesn't lower quality

ConvertirDocs copies the pages as they are, without recompressing them, so the merged file looks exactly like the originals. Bookmarks from the original files may be lost. The tool is 100% free, needs no sign-up, and runs in your browser, so your documents never leave your device.

Then check the size limit

Merging adds up the sizes, so the combined file is where limits bite. The IRCC Help Centre lists 4 MB per file for the secure account, the citizenship application, the Permanent Residence Portal and the asylum portal, and 5 MB for the IRCC Portal. If your merged PDF is too big, send it straight to “Compress PDF” and type a target just under your limit.

If the upload fails, confirm you uploaded the merged file and not one of the parts, count the pages, and check the size and extension again.

Frequently asked questions

What happens if I upload two files into one IRCC field?

Only the last one is kept. That's why everything for a field should be merged into one PDF.

Does merging reduce the quality of my scans?

No. Pages are copied without recompression. Only compressing afterwards changes image quality.

Can I include photos in the merged file?

Convert them to PDF first with “JPG to PDF”, then merge that PDF with the others.

My merged PDF is over the limit. What should I do?

Compress it with a target just below your account's limit, such as 3,900 KB for 4 MB. If it still won't fit, re-scan text pages in grayscale.

Is my information sent anywhere?

No. Merging happens in your browser, so the files never leave your device. It's 100% free.
