Choose a quality preset

Presets pick how aggressively Convertr recompresses the PDF. You can switch presets and re-run the conversion at no cost.

Prepress (maximum quality) Highest quality for professional printing. Keeps embedded fonts and images at 300 DPI. Smallest size reduction; best fidelity. Printer (high quality) High quality for desktop printing. Images downsampled to 300 DPI. Modest size reduction with strong fidelity. Ebook (balanced) Balanced size and quality for screen reading. Images downsampled to 150 DPI. Good for email and web sharing. Screen (smallest) Smallest output for low-resolution screen viewing. Images downsampled to 72 DPI. Use only when size matters most. Lossless (qpdf restructure) Re-linearises and recompresses object streams with qpdf. No image downsampling or quality change. Best for already-optimised PDFs.

Convertr uses free open-source tools (Ghostscript and qpdf) to recompress PDFs.

Email-friendly PDFs

Shrink invoices, reports, and contracts so they fit inside common email attachment limits without splitting them across multiple messages.

Faster web downloads

Compress brochures, whitepapers, and product sheets before publishing them so visitors do not wait on slow downloads.

Long-term archives

Use Lossless or Ebook to reduce storage footprint when you are keeping a PDF copy of finished documents.

Mga Madalas Itanong

Is this PDF compressor free?

Yes. Convertr lets you compress PDF files for free, with no account, no watermark, and no software installation.

Will my PDF lose quality after compression?

You choose the preset, so you choose the quality. Prepress and Printer keep images at 300 DPI, Ebook downsamples to 150 DPI for screen reading, Screen targets 72 DPI for the smallest file, and Lossless re-saves the PDF without touching image quality.

Ano ang pinakamalaking sukat ng PDF file?

Maaari kang mag-upload ng mga PDF file hanggang 1 GB, kaparehong limitasyon ng ibang mga tool ng Convertr.

Pribado ba ang mga na-upload na PDF?

Files are processed on Convertr servers and automatically deleted after compression. The tool is built for quick file conversion, not long-term document storage.

Which preset should I pick?

Pick Prepress or Printer for documents going to print, Ebook for email or web sharing, Screen when you need the absolute smallest size, and Lossless when the PDF is already optimised and you only want to recompress the structure.

Sinusuportahan ba ng Convertr ang mga PDF na may password?

Unlock the PDF first if you know the open password and are authorized to modify it. The compressor skips encrypted files it cannot read.
