Frequently asked questions

Will this get my PDF under 300 KB?

Yes — the 300 KB target is preset and the tool compresses to the highest quality that stays under it, so the document stays readable for the reviewer.

Is my PDF uploaded anywhere?

No. The PDF is rebuilt by your own browser and never sent to a server — safe for statements and IDs.

Will the text still be selectable?

For strong compression, pages become images, so text is not selectable. Keep your original if you need to edit it.

When you need 300 KB

The 300 KB limit shows up on portals sitting between the common 200 KB and 500 KB caps, and short scanned documents. Drop your PDF above and it will be compressed to fit.

What to expect

300 KB comfortably fits a few text pages or a single scan while keeping everything clearly readable.

Different limit? The PDF compressor hub covers every size.
