Private by design
The compressor runs locally in your browser. The PDF never goes to VOIDNEON.
THE PDF FILE CORRECTION FACILITY
Grab a PDF File.
Compress some sense into it.
Catch that out-of-control PDF file. Knock some sense into its size and colour. See the damage dealt before you take it back home.
This web Spank! compresses large PDFs to smaller file sizes when the file allows it. You see the real size before and after.
01 / CAPTURE
Bring in the suspect
Drop one PDF File, or a whole gang. They stay on this device.
02 / TREATMENT
Knock some sense into it
Choose how far to go. Stronger treatment changes the contents of a PDF.
A target size is a goal, not a guarantee. Leave it blank for one pass. Selected pages are exported in the order you enter them.
Choose a PDF to begin.
03 / AFTERCARE
Sentence served
Inspect the result before taking it home. You can always download your original file.
PAGE PREVIEW
1 / 1
Preview shows the visible page. Inspect your downloaded PDF before relying on it.
04 / JSON PACKET
Call the Box from your code.
Use the same compressor through a JSON Packet on another page of your website. Pass the PDF as base64, choose the treatment, and receive a base64 PDF with its actual size.
This is a browser JavaScript API. It runs on the visitor's device; there is no server-to-server HTTP compression endpoint.

THE HOUSE RULES
Keep your eyes on the PDF files.
Preserve or punish
Keep My Text can save little. Squeeze the Pages can save a lot, but flattens everything visible into pixels.
No false victories
We show the real before and after sizes. If repacking grows the file, you still get the original.
