Pro Tip: If your PDF contains interactive fillable fields, run it through our Flatten PDF tool first to strip form scripts.

Select Compression Level (Light, Medium, or Heavy)

Select 'Medium Compression' (150 DPI) for standard documents or 'Heavy Compression' (72 DPI) if your file is currently over 15MB and must hit the strict 1MB threshold.

Pro Tip: Heavy compression targets embedded high-res photo assets while leaving text as mathematical vector curves.

Verify File Size Readout Against Portal Limits

Review the instant before-and-after comparison showing the exact byte reduction (e.g. 8.4 MB reduced to 840 KB). Inspect the page thumbnails to confirm visual clarity.

Pro Tip: If your file is still slightly above 1MB, split the PDF into two parts using Split PDF or remove redundant scanned pages.

Frequently Asked Questions

Will compressing my PDF to under 1MB make the text look blurry?

No. Unlike pixelated raster images, typography in PDFs is represented as mathematical vector outlines. Our compression engine downsamples embedded raster images and strips invisible metadata streams, leaving every paragraph, header, and signature crisp and sharp at any magnification.

Which compression level should you use: Light, Medium, or Heavy?

Light (20-30% reduction, 300 DPI) is best for portfolios and documents intended for high-res print. Medium (40-50% reduction, 150 DPI) is the optimal balance for 99% of business reports and resumes. Heavy (60-75% reduction, 72 DPI) is engineered to hit strict 1MB and 2MB upload caps.

Why is my PDF still over 1MB after Heavy compression?

If a document is packed with dozens of 600 DPI full-page color scans, even Heavy compression might result in a 2MB-3MB file. In this case, chain tools: first use Split PDF to divide the document into two sections, or use Flatten PDF to strip unneeded form elements.

Does compression affect hyperlinks, bookmarks, or form fields?

No. All hyperlinks, digital table-of-contents bookmarks, and form annotations remain fully functional after compression.
