Questions
How do I make a PDF smaller than 300 KB?+
Add your PDF, keep the target at 300 KB and press Compress. PDFNina tries several image resolutions and keeps the sharpest version that’s still under 300 KB.
Will the text get blurry?+
No. Text and vector graphics aren’t touched; only photos and scanned images are recompressed, and only as much as needed.
What if it can’t get under 300 KB?+
We show how close we got. Very long documents or pages with many photos may need splitting, removing pages or grayscale to fit a strict limit.
Is my file uploaded?+
No. Compression runs entirely in your browser, so your document never leaves your device.
