Offline PDF tool
This page explains work with PDFs offline, what actually changes inside the file, and what to expect. The tool itself runs entirely on your device.
How to work with PDFs offline
Three steps:
- Open the tool and drop your PDF in — or choose it from your device.
- Pick a setting. Balanced suits most documents.
- Download the result. Nothing was uploaded at any point.
What to expect
Savings depend on what the document holds. Scans and photo-heavy files commonly drop by 70–95%, because the images dominate and re-encoding them is very effective. A text-only report that was already compressed may hardly change — the tool reports the real figure rather than inflating it. Text and vector graphics are never touched, so they stay sharp at any zoom.
Practical tips
- Check the saving before you keep the result. If a file barely shrinks, it was already efficient and the original is the better copy.
- Scanned documents compress the most, because the whole page is a photograph. Text-only PDFs have little left to remove.
- Keep an original. Image re-encoding is lossy, so compressing the same file repeatedly degrades it each time.
