Pick a PDF and get a copy of 100 KB or less. A larger PDF is saved as images, so its text is no longer selectable; a smaller one keeps it.
How it works
- Choose a PDF document.
- Lossless mode re-saves the file without touching the content; guaranteed mode turns the pages of a file over the limit into images.
- The tool finds the highest resolution and quality that fit the limit.
- Download the smaller PDF.
Didn’t fit? What to do
- A page or two of a scan stays readable at 100 KB: send only the pages the form asks for.
- Black-and-white scans compress far better than color photos of documents.
- Crop phone photos of documents to the paper edge before making the PDF.
- If the form allows several files, split a long document instead of squeezing it into one.
Frequently asked questions
Why does my text look blurry at 100 KB?
Each page gets only a small share of 100 KB, so pages are saved at a lower resolution. Fewer pages means more detail per page.
Why can't I select text after compressing?
To fit in 100 KB, each page of a larger PDF is rendered as an image. The document looks the same but is no longer searchable. A PDF already under 100 KB keeps its text.
Is 100 KB 100,000 or 102,400 bytes?
Forms differ. The tool targets 100,000 bytes, which passes either way.
