Compress a PDF
Make a PDF small enough to email or upload. Compression re-encodes the images inside your document at a sensible quality while leaving text and vector content sharp — the usual way scanned documents balloon to 40 MB, reversed.
Results are reported honestly: you'll see the real before and after sizes. Scan-heavy files often shrink by 80–90%; a text-only PDF that is already efficient may barely change, and we'd rather show you that than fake a number.
- 1
Upload the PDF (up to 25 MB).
- 2
Compression re-encodes images at balanced quality.
- 3
Download the smaller file and check the real size saving.
The default level balances size against readability and is the right choice for sharing scans and reports. The full app adds Low/High presets and a custom DPI/quality mode when you need finer control.
Measured example from our test suite: a 15.7 MB scanned document compressed to 1.0 MB (93.3% saved) with clearly readable output.
Compress PDF — questions
Will text stay sharp?
Yes — text and vector graphics aren't rasterised; only embedded images are re-encoded.
Why did my PDF barely shrink?
It was probably already efficient (mostly text, few images). Compression mainly wins on scans and photo-heavy files.
Is there a quality trade-off?
Images are re-encoded at a balanced quality chosen for documents. If you need pixel-perfect archives, keep the original — it's deleted from our side within 24 hours either way.
