PDF CompressorSmaller PDFs.
Same sharp text.
Drop in a PDF and get a much smaller copy that's still easy to read on screen. Image-heavy files shrink the most. Everything runs on your Mac.
Built to shrink files, not quality
The compressor only reworks what makes PDFs heavy: oversized images and leftover data. Your text, fonts and vector graphics stay as they are.
Text stays text
Pages are never turned into pictures. You can still select, search and copy everything in the document.
Smart image resizing
Images are scaled down only when they're sharper than the page can show, then saved as efficient JPEGs.
Private by design
No uploads, no account, no tracking. Files are processed on your Mac and never leave it.
Never bigger
If a file can't be made smaller, you get an unchanged copy. Originals are never touched.
Batch friendly
Drop in a stack of files and compress them in one go. Each copy is saved next to its original.
Clean metadata
Hidden extras like thumbnails, editing leftovers and document metadata are removed.
Preview and compare
Check any file in Quick Look, then flip between the compressed copy and the original to judge quality.
Light or dark
Follows your Mac, or pick Light or Dark in the app.
Pick how small
Four presets cover everything from print to email. Results from a 3-page, 39.5 MB photo-heavy PDF:
| Preset | Best for | Image detail | Result |
|---|---|---|---|
| Light | Printing | up to 300 dpi | 6.4 MB |
| Medium | Reading on screen (default) | up to 150 dpi | 752 KB |
| Strong | Email and upload limits | up to 110 dpi | 139 KB |
| Lossless | No image changes at all | original | ≈ original |

Questions
Are my files uploaded anywhere?
No. Compression runs entirely on your Mac, and the app makes no network requests.
Where is the compressed file saved?
Next to the original, named name-compressed.pdf. The original is never modified.
Why did a file barely get smaller?
PDFs that are mostly text and vector graphics are often already compact. The biggest savings come from scans and photo-heavy documents.
Does it work with password-protected PDFs?
PDFs that open without a password but restrict editing work and keep their protection. PDFs that need a password to open aren't supported in the app yet.
Is it free?
Yes, this release is free.
