How It Works

  1. 1

    Upload your PDF

    Drop in your PDF. Typical files that need to reach 1MB include scanned contracts (5–20MB), exported PowerPoint presentations (10–50MB), and photo albums in PDF form.

  2. 2

    Apply appropriate compression

    For a 1MB target from a 5MB file, Medium compression is usually sufficient. For larger files (20MB+), use High compression, which reduces image DPI to 96 pixels per inch.

  3. 3

    Download the 1MB-or-less PDF

    Check the output size shown before downloading. If the result is still over 1MB, run it through the Split PDF tool to remove unnecessary pages, then re-compress.

Frequently Asked Questions

Can any PDF be reduced to under 1MB?+
Almost all PDFs can reach under 1MB with appropriate compression. Exceptions include PDFs with dozens of high-resolution full-page photographs, which may bottom out around 1–3MB.
Is 1MB a good file size for a PDF resume?+
A resume PDF should ideally be under 500KB — recruiters and ATS systems sometimes reject large files. Use Medium compression to safely stay under 1MB, or remove any embedded high-res images.
Does compressing to 1MB make a PDF slower to open?+
No — smaller PDFs open faster. Compression reduces file size, which means faster transfers and quicker rendering in PDF viewers.
