Frequently asked questions
How much can a PDF be compressed?
Typical savings are 40–80% on document PDFs with embedded images. Text-only PDFs may compress 10–30%. Already-optimised PDFs may not compress further — we return the original in that case.
Will text stay selectable?
Yes. We only re-encode raster images; text, vector graphics, bookmarks, and hyperlinks are preserved.
How much will my PDF shrink?
Usually 40–80% smaller with no visible quality drop. Already-optimised PDFs may not compress further — in that case we return the original.
Are my PDFs stored anywhere?
No. Files are processed in a system temp folder and deleted immediately.
Is there a file-size limit?
Up to 50 MB per PDF, 10 PDFs per batch. No limit on batches.
