Frequently asked questions

What's the maximum file size for PDF/A Public Tender Compliance Converter?
The processed file must be under 50MB. Photo & PDF Desk uses adaptive compression, starting from the highest quality setting that still preserves legible text, until the file fits.
Will compression blur my text or signatures?
No. Text, form fields, and vector graphics (including scanned signatures saved as vectors) are never rasterized or blurred β€” only embedded raster images inside the PDF are progressively downsampled to hit the size target.
What format will I get back?
A strict PDF/A-1B file (ISO 19005 compliant) with fonts embedded, transparency flattened, and an sRGB color profile attached β€” suitable for long-term digital archival requirements.
Can I choose specific pages to keep?
Yes β€” enter a page range like "1-3,5" in the editor and only those pages are kept before any other processing runs.
What's the difference between PDF and PDF/A?
A regular PDF can reference external fonts, contain JavaScript, or use encryption β€” all of which can make a file unreadable years later if the referenced resources disappear. PDF/A forbids all of that and embeds everything the file needs (fonts, color profile) directly, guaranteeing it renders identically decades from now.
