Compression level
Combine your PDFs into one file and compress it under the 4 MB IRCC upload limit — all in your browser.
This is the one most people come here for. Portals often want a single file under 4 MB, and a scanned document blows past that fast. Combine your pages into one PDF and squeeze it under the limit in a single step, then you will see a clear green tick when it is ready to upload.
Review the finished result carefully before using it for office work, an employer, a school, the IRCC portal or another government website. Check page order, dates, names, signatures, readability and the file-size limit for the exact upload form. Keep your original file so you can make changes or provide a clearer copy later.
Add your files, merge them, and pick a compression level. The tool shrinks the result and tells you when it is under 4 MB.
Medium keeps most documents clear. High saves more space but softens images, so use it only if you are still over the limit.
