Questions
FAQ
Privacy, quality, and what to expect from local compression.
Why is SizePDF good for scanned PDFs?
Scans are image-heavy. Our compressor targets exact sizes that portals demand for those files.
Does it work on phone photo PDFs?
Yes. Photo-based and flatbed scans are the primary use case.
Is processing local?
Yes — 100% local, no upload, private by design.
Will OCR text remain?
Strong compression rasterizes pages, so selectable text is usually lost. That is expected for many upload portals.
