When you need this
- A document needs to fit comfortably under a 5 MB attachment or upload limit.
- You want to preserve more quality than a very small target would allow.
- You are sending a long report that is currently 20 MB or more.
- You want a consistent output size across several documents.
Steps
-
Open the PDF
Load the document in PDF JustFit from Files or via the share sheet.
-
Enter 5 MB
Type 5 MB as the target size.
-
Choose Smart compression
At 5 MB there is usually room to keep text selectable, which is the better result for most documents.
-
Compare the pages
Check the before-and-after comparison to confirm images and small text still look right.
-
Export
Save or share the result. History keeps the size saving for later reference.
A larger target means better quality
Because PDF JustFit searches for the best quality at your chosen size, a 5 MB target will generally produce a noticeably better result than a 2 MB target on the same document.
Consistent output for batches
When several documents need to go to the same place, setting the same target size for each produces a predictable set of outputs.
Privacy and limitations
Very large scans may need Maximum mode
A 300-page scan can be large enough that a 5 MB target is demanding. In that case Maximum compression rasterises pages to reach the smallest possible file.
Frequently asked questions
How do I compress a PDF to 5 MB?
Enter 5 MB as the target size in PDF JustFit, choose a compression mode, review the before-and-after comparison and export.
Is 5 MB better than 2 MB for quality?
Generally yes. A larger target gives the solver more room, so it can preserve more quality while still reaching the size you asked for.
