Compress PDF to 100 KB
Upload a PDF and get a copy under 100 KB. The tool tries its compression levels from lightest to strongest and keeps the lightest one that fits, so you get the best quality that meets the limit.
What to expect
100 KB is realistic for a short text document or one scanned page at reduced image quality. Multi-page scans often cannot fit without becoming hard to read, so split the PDF first if the portal allows several uploads.
How to compress pdf to 100 kb
- Upload your PDF. The target is already set to 100 KB.
- Select “Compress to under 100 KB”. The tool tries a few compression settings, which can take a minute for long documents.
- Download the result. If the target could not be reached, you get the smallest version possible and a note saying so.
Frequently asked questions
How do I compress a PDF to 100 KB?
Upload it above and select “Compress to under 100 KB”. The tool keeps the lightest compression that brings the file under 100 KB and shows the before and after sizes.
Will the text stay selectable?
Pages that contain only text are copied into the new file unchanged, so their text stays sharp and selectable. Pages with photos or scans are re-compressed as images, so text on those pages becomes part of the image.
Why can my PDF not reach 100 KB?
Text, fonts and vector graphics are kept as they are, so if they alone take up more than 100 KB, compressing the images cannot bring the file under it. Splitting the PDF into smaller parts with Split PDF usually helps.
Is my PDF uploaded?
No. The PDF is compressed in your browser and never leaves your device.
