Slim down PDFs with an honest metadata cleanup — no recompression, no quality loss. Free, private, and clear about what it does.
Files are processed locally and never uploaded.
Drop your PDF into the compressor above — it stays on your device.
The tool strips excess metadata — titles, author fields, and hidden bloat.

PDFs accumulate weight from three sources: embedded fonts, images, and metadata — the invisible cargo of titles, author names, editing history, and application data that rides along inside the file. A document that's been through several editors can carry surprising amounts of it.
Not all of that weight is removable without trade-offs. Recompressing images shrinks files dramatically but degrades quality; stripping metadata shrinks them modestly but touches nothing visible. This tool does the second, honestly.
Let's be explicit: this tool performs a metadata cleanup. It removes the title, author, and other document-info fields plus hidden application bloat, then rewrites the file compactly. Your text, images, and layout come through byte-identical.
What it does not do: recompress the images inside your PDF. If your 40MB scan is 39MB of page images, metadata cleanup won't move the needle — and we'd rather tell you that upfront than sell you a miracle.
For text-heavy documents — contracts, reports, forms, ebooks — metadata and structural bloat can be a meaningful fraction of the file. Shaving a few hundred kilobytes is often exactly what's needed to slip under an email attachment limit or a portal's upload cap.
It's also the right first step before anything drastic: run the honest cleanup, check the new size, and only then decide whether the images need attention too.
If your PDF is mostly scanned page images, the images are the file — metadata is a rounding error. No honest metadata tool will fix that; the fix is compressing the images before they become a PDF.
The practical path: compress your JPGs with our image compressor first (a 100KB-per-page target keeps scans email-friendly), then build the PDF from the compressed images with our JPG-to-PDF converter. That combination beats any metadata trick by orders of magnitude.
Because nothing is recompressed, quality cannot change — the guarantee is structural, not a promise. What you see in the original is pixel-for-pixel what you get in the output.
And the processing never leaves your browser, which matters for the contracts and records people typically compress. No upload, no account, no retention question to ask.
Honestly: modestly. Metadata cleanup typically saves kilobytes to a few percent — enough to slip under an attachment limit, not enough to rescue a 50MB scan. If images dominate your file, compress the images first instead.
No — that's the point of this approach. Only metadata is removed; text, images, and layout pass through untouched. The visible document is identical before and after.
Because the file is almost entirely page images, and this tool deliberately doesn't recompress images. Compress your source images first, then rebuild the PDF — that combination shrinks scans dramatically.
The content is untouched — only invisible metadata fields are removed — so the document's substance is unchanged. That said, for anything legally sensitive, keep the original and check whether the recipient requires the file unmodified.
