Compress PDF to 100 KB free

Official portals (courts, grants, universities, applications) often cap attachments at 100 KB. Upload your PDF, set the target and it compresses until it fits — free, no sign-up, no watermark.

Open the tool

How it works

  1. Upload the PDF (up to 50 MB).
  2. Pick the target size: 100 KB.
  3. Download the result. If it can't fit even at maximum compression, you get the smallest possible file and are told clearly — never a broken output.

Frequently asked questions

How do I get a PDF under 100 KB?

With “Compress to a size”: set 100 KB as the target and the tool tries decreasing quality levels until it fits, keeping the best quality that stays within 100 KB.

Does the document lose quality?

Images are recompressed and the structure optimised; text stays text. Final quality depends on how much needs shaving — the best quality that meets the target is kept.

Is it really free with no sign-up?

Yes. No account, no ads, no watermark. Files are processed on EU servers and deleted when done.

Free, no sign-up, no ads. Files are processed in the EU, PII is encrypted before any AI and everything is deleted when done.
