Frequently asked questions
Are my PDFs uploaded to servers?
No. All QuelloAI PDF tools process files directly in your browser using pdf-lib and PDF.js — your documents never leave your computer.
Are the PDF tools free?
Yes, with a limit of 3 uses per day for non-registered users and 10 uses per day on the free plan. The Pro plan offers unlimited uses.
What is the maximum file size?
PDFs can be up to 50 MB. For merging, the combined total of all files must not exceed 50 MB.
Does PDF compression keep text selectable?
No. Compression works by rasterizing each page — text becomes non-selectable after compression. This approach is ideal for scanned documents but not for PDFs with editable text that needs to be preserved.
Can I convert any PDF to images?
Yes, as long as the PDF is not password-protected. Scanned PDFs are also converted, but the image quality depends on the original scan resolution.
