PDFSlim - Compress PDF

PDFSlim — Smart PDF Compressor

Tired of PDF files that are too large to email, upload, or share? PDFSlim compresses any PDF to your exact target size in seconds — right from your phone. No desktop software needed. No cloud uploads. Everything happens on your device, keeping your documents private.

WHY CHOOSE PDFSLIM?

Most PDF compressors either destroy your document quality or lock features behind a paywall. PDFSlim gives you full control — you choose the exact output size you want, and the app does the rest.
