How to get a PDF under 1 MB

This tool is set to compress your PDF to 1 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.

1 MB comfortably fits a text document of any normal length. Scanned pages are much heavier, so how many fit depends on colour and resolution.

As a rough guide, 1 MB holds about 40 pages of plain text, 8 grayscale pages scanned at 150 DPI, or 2 colour pages at 150 DPI.

Limits of this size are typical on job sites, university applications, insurance claims and many online forms.

  • 1 MB = 1,024 KB (1,048,576 bytes).
  • Budget per page under 1 MB: about 205 KB for a 5-page file, 51 KB for 20 pages, 20 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 make a PDF less than 1 MB?

Add your PDF. The target is already set to 1 MB; nothing to configure. Click Compress and download the smaller PDF. It is preset to get the file under 1 MB and shows the final size.

Can I get a 10-page scan under 1 MB?

It is tight: about 102 KB per page. Tick grayscale and expect the Strong level; if text becomes hard to read, split the document into two files.

Why is my PDF still over 1 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 1 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.
