Compress & convert PDF — free
Two essentials: shrink a PDF below the 25 MB email cap, or build a PDF from JPG/PNG/WEBP images. Both tools are free, no account, no watermark. Image conversion runs in your browser (no upload). Compression runs server-side with files deleted from memory immediately after delivery.

Frequently asked questions
How much can I compress a PDF without losing quality?
Typical reduction is 30-80% depending on content. PDFs with embedded high-resolution images compress most (50-80%); text-only PDFs compress less (10-30%). PDFree's medium setting preserves visible quality for most documents while halving file size.
What image formats can I convert to PDF?
JPG, PNG, and WEBP are supported. You can convert one image or batch up to 20 images into a single PDF. Image order is preserved by upload order, with drag-to-reorder before generating the final file.
Does compressing a PDF affect text searchability?
No. Compression reduces image and font data but preserves the text layer. After compression, text remains searchable, selectable, and copyable. If your PDF was a scanned image with no text layer to start, compression won't add OCR.
What's the file size limit for compression?
50 MB on the free plan for server-side compression. JPG-to-PDF conversion happens in your browser and supports up to 200 MB total input size.
