When Should You Compress?
Not every PDF needs shrinking, but compression is a lifesaver in these specific scenarios:
Engineered for Quality
Our tool doesn't just 'zip' files; it intelligently reconstructs your PDF to be as efficient as possible.
Intelligent Image Resampling
Specifically targets high-res photos within your PDF, downscaling them to 144 DPI for crisp screen viewing without the heavy file weight.
WebAssembly Processing
Uses high-performance local processing to shrink large documents in seconds without your data ever leaving your browser window.
Bulk Document Shrinking
Process your entire folder of PDFs at once. Set your preferred quality level once and apply it to every file in the batch.
Metadata Stripping
Automatically removes hidden bloat like creator history, unused thumbnails, and redundant document metadata for a leaner file.
What Actually Gets Compressed?
PDFs are often bloated because they contain data meant for high-end printing, not screen reading. Our tool targets three main areas:
Image Downsampling
Most PDFs contain images at 300+ DPI (dots per inch). We resample these to 144 DPI, which looks identical on your screen but uses 1/4th of the data.
Font Streamlining
Design software often embeds the entire character set of a font. Our engine can strip out unused characters, keeping only the 'glyphs' needed to render your specific text.
Structure Flattening
We remove hidden layers, undo history, and technical metadata that design tools like Photoshop or InDesign leave behind in the PDF export.
