Compress a PDF to an exact file size such as 100KB, 200KB or 1MB, free and in your browser. Reduce PDF size for online form uploads — your document is never uploaded to a server.
Need a PDF under a strict upload limit? The PDF compressor reduces any PDF to an exact file size — 100KB, 200KB, 1MB, whatever a form or email allows — and it all happens in your browser, so your document is never uploaded to a server.
It works by rebuilding the PDF at the highest quality that still fits your target. This makes it ideal for scanned documents, forms and image-heavy PDFs that are too large to upload.
Open the PDF compressor, add your file, type the target size (for example 200 KB), and click Compress. The tool rebuilds the PDF to land under that size, all in your browser.
This tool rasterises each page to force the file under a strict size limit, so text becomes part of the page image rather than selectable text. That is the reliable way to hit an exact KB target and is fine for uploads and scanned documents.
No. The PDF is processed entirely in your browser, so it never leaves your device.

Yes — use the bulk PDF compressor to shrink many PDFs together and download them as a ZIP.
Working with several files or images instead? Try the bulk PDF compressor, the image compressor, or the document resizer.
