Ką daro kiekvienas pasirinkimas
Convertr exposes the underlying Ghostscript and qpdf options as plain-language presets. Quality and final size are entirely your choice; no preset is forced.
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.

Dažniausiai užduodami klausimai
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.
Koks yra maksimalus PDF failo dydis?
Galite įkelti PDF failus iki 1 GB, toks pats apribojimas kaip ir kituose Convertr įrankiuose.
Ar įkelti PDF failai yra privatūs?
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.
Ar Convertr palaiko slaptažodžiu apsaugotus PDF?
Unlock the PDF first if you know the open password and are authorized to modify it. The compressor skips encrypted files it cannot read.
