Frequently asked questions
How much smaller will my PDF get?
Scanned and photo-heavy PDFs often shrink 50–90%. Text-only PDFs are usually already compact.
Will text become blurry?
No. Only embedded images are recompressed; text and vector graphics stay sharp.
Is there a size limit?
No fixed limit — it depends on your device's memory.
