Reduce file size while preserving content
It depends on the file's contents: PDFs full of high-resolution images typically shrink 50-90%, while text-only PDFs (already compact) shrink less. Pick a compression level and NamahaPDF re-encodes embedded images and strips redundant data accordingly.
There's a trade-off you control: lighter presets keep images near-original quality with modest size savings, while stronger presets downsample images further for maximum size reduction. Text stays crisp at every level since it's vector data, not an image.
Yes. Compression runs entirely in your browser — the file is never uploaded to a server, so confidential or regulated documents never leave your device.
