How do I compress a PDF?

Upload the PDF, choose a quality level or a target size, and click Compress file. We re-compress the JPEG images inside it in your browser, then you download the smaller PDF.

Can I compress a PDF to a specific size like 200 KB?

Yes, if the file can get that small. Switch to Target size and enter 0.2 MB, and we'll get as close as we can without going over. PDFs that are mostly text, or whose images aren't JPEGs, may not shrink that far.

Does compression reduce quality?

For images, yes — lower settings mean less sharpness. Text in a PDF isn't touched, so it stays crisp.

Why didn't my PDF get much smaller?

Most of a PDF's size usually comes from its images. If yours is mostly text, or its images are already efficiently stored, there's little to save. We'll tell you when that's the case.

Which file types can I compress?

PDF, JPG, PNG, WEBP, Word (.docx) and Excel (.xlsx), up to 25 MB.

No. The compression runs in your browser, so the file stays on your device.

What it can compress

Images

JPG, PNG and WEBP images are re-encoded at lower quality and resolution.

PDFs

JPEG images embedded in a PDF are re-compressed. Everything else in the PDF is left untouched.

Word and Excel files

Pictures embedded in .docx and .xlsx files are re-compressed and the file is repacked more tightly.

Quality slider or target size

Pick how much quality to give up, or tell us the size you need and we'll get as close as we can without going over.

Same format out

A PDF stays a PDF and a .docx stays a .docx — nothing is converted.

You see the original and new sizes, and a plain note if a file couldn't be made meaningfully smaller.

Good to know

PDF compression is best-effort. We re-compress the JPEG images inside a PDF but leave other content alone, so text-only PDFs and scans stored in other image formats may not shrink much.
Lower quality means less sharp images. PNG images shrink by reducing their resolution.
A target size is a goal, not a guarantee. Very text-heavy files may not reach it.
If a file is already smaller than your target, it's returned as it is.
Your file never leaves your device.
Files up to 25 MB are supported.
