How to compress a PDF under 1MB

Why PDFs get so big

Most of a PDF file size is images. A scan or a deck full of photos can be many megabytes, while the text itself is tiny. Compression re-encodes those images at a sensible quality, so a high setting can shrink a file dramatically with little visible difference on screen.

Shrink a PDF in three steps

  1. Open the free Compress PDF tool and add your file.
  2. Choose medium or high compression for the smallest size.
  3. Download your compressed PDF - usually well under 1MB.

Frequently asked questions

Will compression ruin the quality?

No. Medium compression is visually near-identical for most documents. Use high compression for the smallest size when the PDF is mostly for screen viewing.

Why do I need a PDF under 1MB?

Many email and upload forms cap attachments at 1-2MB. Compressing keeps your document under the limit without splitting it.

Is it private?

Yes. Your file is processed in isolation and deleted automatically within 2 hours. No signup, no tracking of your content.
