Frequently Asked Questions
Why can compression make files bigger?
If a PDF contains no images, there is little to compress — re-saving can even add overhead. The tool warns you when the result is larger.
Will text become blurry?
No — only embedded images are re-encoded; text and vector graphics remain sharp.
