Getting a PDF under 400 KB
At 400 KB a short scanned document, like a four or five page transcript or a lease, usually fits at around 100 to 150 dpi. That is sharp enough to read small print on screen.
Documents with photos or colored backgrounds are the harder case, because every page is a full-color image. Those step down further, and the result is the gentlest setting that still fits under 400,000 bytes.
Tips
- Remove blank pages, including the backs of single-sided sheets that a duplex scanner picked up.
- A document created on a computer, rather than scanned, is often already far under 400 KB. Try the original file before a scan of a printout.
- Zoom in to 100% on the result and read one line of small print before you upload it.
How it works
- 1
Drop your file
A PDF or an image. It goes over an encrypted connection and nowhere else.
- 2
Pick your limit
Choose the size the form asks for. We start with a cleanup that changes nothing you can see.
- 3
Download it
If it needs more, we find the gentlest quality setting that still fits, and delete everything soon after.
Questions
Is it free?
Yes. There is no sign-up and no watermark.
What happens to my file?
It is processed on our server and deleted automatically: the original 5 minutes after the run finishes, the compressed file after 10. A file you upload but never compress is deleted within 30 minutes. You can also delete everything right away with Delete now.
Will it look worse?
We try a lossless cleanup first, which does not change how the file looks. Only if that is not enough do we lower image quality, and we pick the gentlest setting that still fits your size.
What if my file cannot get that small?
You get the smallest version we could make and a clear note saying so, instead of a file that silently misses the limit.
Why does the size page aim a little under its limit?
Some sites count a kilobyte as 1000 bytes and others as 1024. We aim under the stricter one, so a 200 KB page aims for 200,000 bytes and the file passes either way.
