Frequently Asked Questions
How does PDF compression work?
Toolatu uses Ghostscript to rebuild the PDF and downsample embedded images according to the selected quality preset.
Which quality should I choose?
Recommended is best for most files. Strong creates smaller PDFs, while Light keeps more visual detail.
Can encrypted PDFs be compressed?
Password-protected or encrypted PDFs cannot be compressed unless they are unlocked first.
Are files private?
Files use temporary storage and signed downloads, then cleanup removes old uploads automatically.
