Use this compress PDF tool to make a PDF file smaller so it fits an email attachment limit or a website upload form. Many portals ask for a PDF under a set size, such as 100KB, 200KB, 500KB or 1MB, and scans or image-heavy documents often exceed it. Add your file, compress it, then check the new size before you submit. The result depends on what is inside the PDF: files full of photographs or scanned pages usually shrink a lot, while text-only PDFs that are already compact may shrink very little. Because the work happens in your browser, your document is never uploaded to a server. That is useful for ID scans, contracts, bank statements and application forms that you would rather not hand to a stranger's website. There is no account, no watermark promise to read through and no file count limit. It is free, and after the page loads it keeps working offline.

Frequently asked

How do I compress a PDF to 100KB or 200KB?

Compress the file and check the output size. If it is still too large, try compressing a copy again or reduce the number of pages, since image-heavy files shrink the most.

Is it safe to compress a PDF online with this tool?

Yes, in the sense that your file is not uploaded. Compression runs in your browser, so the document stays on your device.

Why did my PDF barely get smaller?

PDFs that contain mostly text or were already optimized have little left to remove. Scanned or photo-based PDFs gain the most.

Is compress PDF free with no account?

Yes. It is free, needs no sign-up and works offline once the page is loaded.
