FAQ

Is my PDF uploaded to a server?
No. Compression runs entirely in your browser tab.
Which preset should I use?
Balanced works for most files. Use light for text-heavy PDFs when you want to avoid image recompression, or max for scan-heavy files. Compare the download to your original before you rely on it.
Is compression lossless?
No preset guarantees a byte-identical file. The light preset skips recompressing embedded images but may still change PDF structure. Balanced and max reduce image quality for smaller size.
Is PDF Compressor free?
Yes, free on FindMeTool with no account required.
Is my data uploaded to a server?
For client-side tools, input stays in your browser. Do not paste secrets you would not store locally.
