Questions about Compress PDF
Is the PDF uploaded? +
No. Compression runs locally in your browser.
Will my text still be readable? +
Yes. Text stays as real PDF text. Only embedded images are recompressed; stronger levels shrink images more.
What if the file does not get smaller? +
Text-heavy PDFs with few images often barely shrink. The tool shows both sizes and never fakes a reduction.
