Questions
How do I make a PDF smaller than 1 MB?+
Add your PDF, keep the target at 1 MB and press Compress. PDFNina tries several image resolutions and keeps the sharpest version that’s still under 1 MB.
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 1 MB?+
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.
