Compress PDF to 300 KB
CurePDF can compress a PDF toward a 300 KB target — enter 300 KB under "Custom target size" and the tool works through progressively stronger compression until it's at or near that size. 300 KB comfortably fits short documents with a handful of images.

Things to Keep in Mind
At 300 KB, the compressor usually has enough room to keep a handful of small-to-medium images looking reasonably sharp, using gentler settings than a 100-200 KB target would require. Longer documents (10+ pages) or ones with several full-page images will likely still need stronger compression to get there, with more visible impact on image quality.
Frequently Asked Questions
What kind of PDF fits comfortably at 300 KB?
A short document — a handful of pages — with a few small-to-medium images. Longer or more image-heavy PDFs will need stronger compression to reach it.
Is 300 KB better than 200 KB for image-heavy PDFs?
The extra headroom does help — images generally survive with a bit more visible detail at 300 KB than at 200 KB, though very image-dense documents may still need more compression.
Does CurePDF guarantee exactly 300 KB?
No — like every target here, it's best-effort. The tool tries progressively stronger settings and returns the smallest safe result if the exact number can't be reached.
Can I use this on a scanned document?
Yes, though scanned pages (which are essentially one big image per page) need more compression than typed text to reach any given target, including 300 KB.
