How to compress a PDF to 1 MB
- Drop your PDF, or several PDFs and photos of documents, on the box. They are combined into one file in the order you add them.
- The target is already set to 1 MB. Tick Black and white if colour is not needed.
- Press Compress to target. The tool picks the best quality that still fits and shows a before and after preview.
- Check that the text is readable, then download.
What fits in 1 MB
A 1 MB limit suits most short documents. A few scanned pages usually fit at a comfortable reading resolution; longer scans are reduced further. Black and white helps colour scans fit at a higher resolution.
The limit is counted in decimal units (1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes), so the file is accepted whichever way a website counts. Everything runs in your browser; nothing is uploaded.
FAQ
Where is a 1 MB PDF limit common?
On application systems that take one file per document. For example, OSCAR, the US federal judiciary's clerkship application system, requires documents other than transcripts to be under 1 MB. Always check the instructions of the form you are filling in, because limits differ from system to system.
Can a multi-page scan fit in 1 MB?
Usually, yes. A few scanned pages fit comfortably once they are converted to a lower resolution; long colour documents may need Black and white, which keeps text crisp at a fraction of the size.
My portal wants several certificates in one 1 MB file. Can I do that?
Yes. Drop all the scans or PDFs on the box: they are combined in the order you add them, and the whole file is compressed to 1 MB.
Is 1 MB counted as 1,000 KB or 1,024 KB?
The tool aims for 1,000,000 bytes, the smaller of the two, so the file is accepted whichever way the portal counts.
