Compress PDF to 1 MB

1. Add the PDF you need to reduce to 1 MB.
2. Keep the preselected 1 MB target or enter a different size.
3. Start the 1 MB search and follow its progress; you can cancel at any time.
4. Check whether the 1 MB target was reached, compare the first page, and download your copy.

Target size

Starts at 1 MB. Select a quick size or enter a positive custom value in KB or MB. Units use 1024 bytes per KB.

Remove saved document details

Optionally remove title and author properties; names printed on pages remain.

Unlocked PDF documents, including text and images. Signed files require confirmation to create a changed copy.

The requested size is an aim, not a guarantee. Large image files may stay above it even after compression. Images are not reduced below 100 DPI.

Tests covered 1,000 simple text pages and generated image PDFs up to 200 MB. Large files may use the full search time and remain above your target.

Tested in Chromium, Firefox and WebKit. Large-file checks used a 100 KB target; the other starting sizes were checked with a 50-page PDF.

No. A long document or already compact file may not fit within 1 MB. The tool returns the smallest validated result it found and tells you when the target was not reached.

No. Selectable text is kept. Pictures may be resized, re-encoded or converted to grayscale; original files stay unchanged.

At most 32 attempts within two minutes after analysis. It may finish earlier when no further search is useful.

Open the result preview to compare original and result side by side. Check small print and important values before using the downloaded file.
