Frequently Asked Questions
How does a PDF compressor work?
PDFs are usually large because they contain high-resolution images. The compressor lowers the DPI of these images and removes unnecessary metadata, drastically shrinking the file.
Will my text become blurry?
No, standard text and vector fonts are never compressed. Only raster images (photos) inside the PDF are affected.
What if the file size doesn't change?
If your PDF is primarily text and contains no heavy images, it is already as small as it can be. Compression only works on unoptimized images.
Is it safe for confidential documents?
Yes! The optimization is done via local JavaScript. No files are uploaded to an external server.
Will the text become blurry?
No, the compressor primarily optimizes embedded images, leaving text perfectly sharp.
How much smaller will the PDF get?
It depends on the amount of images in the file, but sizes often reduce by 50% or more.
Is it safe to compress confidential documents?
Yes, because the compression runs locally on your device.
Is this a free pdf compressor?
Yes, this free pdf compressor requires no payment.
What makes it the best pdf compressor?
