How to get a PDF under 15 MB

This tool is set to compress your PDF to 15 MB or less. It tries progressively stronger image compression and stops at the first result that fits, so you keep the best quality the limit allows.

15 MB is a large budget: it is about bringing big scans, photo books or design files under an upload or email cap while keeping them sharp.

As a rough guide, 15 MB holds about 614 pages of plain text, 128 grayscale pages scanned at 150 DPI, or 43 colour pages at 150 DPI (around 15 colour pages at 300 DPI).

This is the range of email attachment limits (Outlook.com 20 MB, Gmail 25 MB) and of many court and business e-filing portals.

  • 15 MB = 15,360 KB (15,728,640 bytes).
  • Budget per page under 15 MB: about 3.0 MB for a 5-page file, 768 KB for 20 pages, 307 KB for 50 pages.
  • Text and vector graphics are never compressed, so they stay sharp.
  • If the limit can’t be reached, you’ll see how close it got. Try grayscale, or split the PDF and upload two parts.
  • The size shown is the real file size in your Downloads folder.

Private by design

Your file is processed by your own browser, in memory. It is never uploaded, stored or seen by anyone, and the page’s security policy blocks it from sending data to other servers.

Frequently asked questions

How do I compress PDF 15 MB?

Add your PDF. The target is already set to 15 MB; nothing to configure. Click Compress and download the smaller PDF. It is preset to get the file under 15 MB and shows the final size.

Can I get a 10-page scan under 15 MB?

Usually yes. That is about 1.5 MB per page, enough for clear grayscale scans and often for colour at medium quality.

Why is my PDF still over 15 MB?

Either the file has very large images that can’t shrink further without becoming unreadable, or it contains many pages of vector content and fonts, which this tool never degrades. Grayscale, or splitting the file, usually gets it under 15 MB.

How do I compress a PDF?

Add the PDF, choose a compression level (or a target size), then click Compress PDF. The result shows the before and after size.

Will compression make my PDF blurry?

Text and vector graphics are never touched, so they stay sharp. Only images are recompressed. Light keeps images close to the original; Strong is visibly softer on photos.

Why didn’t my PDF get much smaller?

PDFs made from text (exported from Word, for example) contain few images, so there is little to compress. Large savings come from scans and photos.
