Key Features

  • ✓ Target quality presets (Standard, High, Maximum)
  • ✓ Exact size targeting
  • ✓ Instant download link

Technical Considerations & Limits

  • • Achieving tight target sizes (e.g. 1mb) on high-resolution documents may introduce minor raster downsampling or JPEG compression artifacts.
  • • Files with complex embedded vector fonts or encrypted DRM cannot be compressed beyond font table minimums.

Frequently Asked Questions

How can I compress a PDF to exactly 1 MB?

Upload your document to our compressor, ensure the 1 MB target limit is selected, and click Compress. The engine will iteratively balance resolution and compression to deliver a file under 1 MB.

Will my text become blurry?

No. Vector text elements are preserved losslessly. Compression focuses on downsampling high-res background images and stripping redundant metadata.

Are my uploaded files safe?

Yes. All uploads are processed on private ephemeral storage and permanently wiped from our servers immediately after processing.
