Choose the right target size
Start here when 2 MB and 4 MB do not mean the same thing in every portal. The right target depends on the real portal or account where you will upload the file, not on guesswork.
When 2 MB and 4 MB mean different things
- Some real upload flows allow 4 MB, while others still force 2 MB.
- IRCC is not one single upload destination, and CEAC is one example of a stricter upload path.
- If you do not know the exact flow yet, start with the strictest reasonable target instead of assuming the larger limit.
Best practical order
- If you know the destination portal, choose the matching profile first.
- If you do not know the exact destination yet, start with GENERAL and the safest reasonable target.
- Let the engine adapt the output automatically for that profile or target size.
- Enable OCR or PDF/A-2b only when the destination actually requires them.
- Review final size and readability before exporting the final watermark-free copy.
Common target sizes
- 1-10 MB for smaller upload limits.
- 15 MB, 20 MB and 25 MB when the system allows a broader file size.
- 2 MB remains one specific stricter case, not the default story for every upload.
