FAQ
Can I compress a PDF to exactly 100KB?▾
The final size depends on your original PDF's content. This preset uses maximum compression settings optimized for the smallest possible output. Documents with mostly text will compress below 100KB easily, while image-heavy PDFs may end up slightly larger. You can further reduce the size by enabling grayscale conversion in the advanced settings.
Will compression affect text quality?▾
No. Text in your PDF remains crisp and fully readable at any zoom level. Only embedded images are resampled to reduce file size. The text layer of your document is preserved exactly as it is in the original.
What if my PDF is already under 100KB?▾
If your PDF is already small, the tool will still process it but the output may be similar in size or even slightly larger due to recompression. In that case, you can simply use your original file.
