Compress a PDF to 100 KB
Squeeze a PDF down to 100 KB for a strict upload limit, without handing your document to anyone.
KB
Nothing is uploaded.
Other online compressors send your file to their servers, process it there, and keep a copy
for some period you cannot verify. This page does the work inside your own browser, so the
file never crosses the network. You can check: open your browser's Network tab and compress
something — there is no upload request.
Why an exact kilobyte limit?
Government and exam portals in India — UPSC, SSC, banking, passport, PAN, university admission forms — reject uploads over a fixed size. That is why people search for an exact number of kilobytes rather than just "compress".
What this does to your PDF
To hit a strict size target the pages are re-rendered as images, which means text in the compressed file is no longer selectable or searchable. For an upload form that enforces a size cap this is normally exactly what you want — but keep your original if you need the text later.
Frequently asked questions
- How do I compress a PDF to 100 KB?
- Select your PDF, set the target to 100 KB, and download the smaller file. Everything happens in your browser.
- Is my PDF uploaded anywhere?
- No. The file is processed on your own device and never sent to a server.
- Does compression affect the text?
- Pages are re-rendered as images to hit a strict size target, so text in the output is no longer selectable or searchable. For an upload that must meet a size limit this is normally fine — but keep your original if you need the text.
- What if my PDF is very large?
- Very large files can exhaust memory in a mobile browser tab. On a phone, files above roughly 25 MB may fail; a desktop browser handles considerably more.
- Is it free?
- Yes — no sign-up, no watermark, no daily cap.
