Why PDF Quality Gets Reduced During Merging
Many online tools secretly ruin your documents when you try to merge them. To save their server bandwidth, they force your files through aggressive compression pipelines.
Image Downscaling
High-resolution images are compressed into lower DPI JPEGs. Your file becomes unusable for print.
Font Re-encoding
Instead of transferring original fonts, bad tools "flatten" your text. Text becomes blurry on zoom.
This is why users specifically search for ways to merge PDF without losing quality online instead of using basic tools.
