One PDF · best for scanned or image-heavy files
How this works, honestly: each page is re-rendered as an image at lower resolution. That is what makes the file smaller — and it means text is no longer selectable afterwards. Scanned and image-heavy PDFs shrink the most; text-only PDFs may barely shrink. We show you the real before/after size, and never claim a percentage in advance.
How it works
1. Add your PDF
Drop it in. Nothing is uploaded.
2. Pick a quality
Lower quality means a smaller file. Medium suits most files.
3. Compare & download
We show the real before/after size. Keep the original if you need selectable text.
Questions
How does compression work here?
Each page is re-rendered at a lower resolution and saved as a JPEG image inside a new PDF. That is how the file gets smaller.
Will my text stay selectable?
No. After compression, pages are images, so text is no longer selectable or searchable. Keep your original if you need selectable text.
Which PDFs shrink the most?
Scanned and image-heavy PDFs shrink the most. Text-only PDFs are already small and may barely shrink — or not at all.
Is my PDF uploaded?
No. Compression happens entirely in your browser; your file never leaves your device.
