Pick a PDF and get a copy of 150 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
- Certificates and mark sheets are usually one or two pages: send only those.
- Scan in black and white or grayscale when the form allows it; color costs more bytes.
- Crop phone photos of documents to the paper edge before making the PDF.
- Check stamps and signatures after compressing: they must still be legible.
Frequently asked questions
Why are stamps and small print blurry at 150 KB?
Pages are saved at a lower resolution to fit. With fewer pages, each one keeps more detail, so remove pages the form does not need.
Why can't I select text after compressing?
To fit in 150 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 150 KB keeps its text.
Is 150 KB 150,000 or 153,600 bytes?
Forms differ. The tool targets 150,000 bytes, which passes either way.
