Frequently asked questions

How much smaller will my PDF get?

We re-write the PDF structure. Size reduction depends on the original; some PDFs shrink, others stay similar. We don’t downsample images in this version.

Is my PDF stored?

No. We process the file in memory and return the result. Nothing is saved on the server.

What’s the max file size?

Default limit is 25 MB per file. You’ll see an error if the file is too large.
