Compress PDF
Compressing a PDF reduces its file size so it fits email attachments, uploads, and storage limits without (usually) hurting readability. Scanned documents and image-heavy reports are the usual culprits behind bloated files.
Craftisle's free compress PDF tool shrinks files in your browser. No account, no watermarks, and your document is not uploaded to a server — the compression happens on your device.
How compression works
The tool re-encodes images and streamlines the file structure to cut bytes while keeping text sharp. You trade a little weight for a much smaller file that is easier to send.
Why shrink PDFs
Many portals cap uploads at 10 or 25 MB. A compressed PDF clears those gates, and smaller files are faster to open on phones and cheaper to store.
Private and free
Compression runs locally, so confidential PDFs are not sent anywhere. It is free with no signup and no output watermarks.
