PDF processing boundaries

These tools operate within browser memory and the capabilities of the browser PDF libraries used on this page. Encrypted, malformed, scanned, XFA, unusual forms, complex signatures, OCR-dependent documents, and advanced desktop-editor features can require specialist software. Always verify generated files before discarding the source.

How to use the PDF Compressor

Choose Preserve structure or a raster profile. For a size goal, enter an optional KB/MB target and let the browser try progressively smaller raster settings, then compare the actual result before downloading.

What PDF compression can change

Compression is a tradeoff between file size and retained document quality. Image-heavy PDFs usually have more room to shrink than text-only files; results depend on the source document and the selected level.

Browser-local workflow

The file is processed by the browser workflow rather than uploaded to WebToolArc. Large or complex files can still be limited by available device memory.
