Things to Keep in Mind
Because 500 KB gives the compressor more room to work with, it can usually stay on the gentler end of its compression ladder — meaning less visible impact on image quality than a much smaller target like 100 KB would need. Very large originals (dozens of pages, or many high-resolution images) may still need stronger settings to get there.
Frequently Asked Questions
Is 500 KB an easy target to hit?
Usually, yes — it's one of the more forgiving targets, and most everyday documents reach it without a noticeable quality trade-off.
Will my images still look good at 500 KB?
In most cases yes, since 500 KB gives the compressor room to use gentler settings. Very image-heavy PDFs may still need stronger compression.
What if my PDF is already under 500 KB?
CurePDF never makes a file bigger than the original, so a file already under your target is returned as-is (or with only light, safe optimization).
Do I need to install anything?
No — it runs entirely in your browser and on CurePDF's servers. No software to install.
