Get a PDF under 100 KB for forms and job portals
Shrink a PDF for upload limits such as 100 KB, 200 KB or 500 KB, check the result size, and try a stronger setting if needed.
How it works
- Open the PDF and note its current size.
- Try compact mode first. If the result is still above your limit, choose an image quality option; lower quality gives smaller files.
- Check the size shown with the result and zoom in on small text before you download. If it is still too big, remove pages you do not need or split the PDF.
There is no guaranteed target size: text-only PDFs may already be small, while photos and scans need an image quality option. The result shows the new size before you download.
When to use this tool
Meet upload limits on exam, government, bank and job portals that ask for a PDF under 100 KB, 200 KB or 500 KB.
What to check before sharing
Image quality options turn pages into pictures: text is no longer selectable and links are removed. Very long or photo-heavy documents may not reach 100 KB without losing readability.
Supported files
Compact mode keeps text and links; image modes remove text search, links and forms. Savings depend on the document.
Inputs: PDF. Performance depends on your device. Download important work before closing the browser; local storage is not a backup.
Troubleshooting
Can you guarantee exactly 100 KB? No. The size depends on the content. The result shows the new size so you can try a stronger setting or remove pages. Why did my PDF not get smaller? It may already be optimized. Image quality options usually help most with scans and photos.
