Compress · In your browser

Smaller file. Same place.

Falcon Compress is a PDF compression tool that shrinks file size by re-rasterising pages at a chosen JPEG quality. Best for scans and image-heavy decks. The work happens on your computer; selectable text is dropped in the process.

The PDF opens in this tab. Pages are re-rasterised on your computer at the quality you choose; the smaller file lands where the original started. By design.

Output is a flat PDF — text selection is dropped.

Why this tool exists

Compression is the most innocent-sounding PDF operation, which is exactly why it is the one most people upload without thinking. A 12-megabyte deck, a hundred-megabyte scan, a fat report attached to an email that bounced — the easiest workflow is also the one that gives the document to whichever “compress PDF” page ranked first in search.

When compression runs on your computer, the document does not pay a tax in trust to lose a few megabytes. The PDF opens here. The pages are re-rasterised in this tab at the quality you pick. The smaller file is the only file that ever existed besides the one you started with.

FAQ

Common questions

Where does the compression happen — on your servers?

On your device, not ours. The PDF is opened, made smaller, and written back inside this browser tab. There is no upload, so a confidential file stays confidential while you shrink it.

How much smaller will my file get?

It depends on what is inside. Documents that are mostly scanned images shrink the most, because images are where the weight usually sits. A file that is already mostly text has less to remove and will compress less.

Will compressing blur my text or images?

Text stays crisp — it is described mathematically, not as pixels, so it is untouched by compression. Images are re-encoded to a smaller size, which trades some fine detail for a smaller file; you choose how far to push that trade.

Can I control how aggressively the file is compressed?

Yes. You set the balance between size and fidelity, so you can favour a smaller file for email or higher quality for print. The chosen setting is applied on your device as the new file is written.

Is there a size limit on the PDF I can compress?

No fixed limit — the bound is your device's memory rather than a server quota. Large scanned PDFs in the hundreds of megabytes compress comfortably on a typical laptop.

How your file stays private

No upload

Opens, parses, rewrites on your device. Nothing about the contents transits a Falcon server.

Zero logs

No filenames, sizes, contents, or per-file telemetry. Operation counts only.

No trackers

Open the Network tab during use. Only first-party JS appears in the request log.

Metadata stripped

Authors, edit history, EXIF, and embedded thumbnails are removed alongside the visible content.

Falcon Crop

pdf.falcon.enterprises/crop

Trim the page, not the trust. Drag a rectangle on the preview and the same frame applies to every page in scope.

Falcon Sign

pdf.falcon.enterprises/sign

A signature should not require an account. Draw it here, stamp it onto the page, save the result — in this tab.

Falcon Compare

pdf.falcon.enterprises/compare

See what changed without sending either version away. The diff is a single PDF with red outlines on every changed region.

Falcon PDF/A

pdf.falcon.enterprises/pdf-a

Archival should not require an archive elsewhere. Pages flatten to images, scripts and fonts drop, and the file is sealed for the long term — here.
