Questions
Can every PDF get under 1 MB?
Scans and picture-heavy PDFs usually can. The tool lowers picture quality step by step until the file fits; if it can't get there without making pictures unreadable, it gives you the smallest version and says so. Text always stays sharp.
Is my PDF uploaded?
No. Your browser re-compresses it on your own device. The file is never sent to our servers or anyone else's.
Which PDFs get much smaller?
Scanned documents and PDFs full of photos - the pictures are usually what makes a PDF big. PDFs that are mostly text are already small and change little.
Will the text get blurry?
No. Only the pictures inside the PDF are re-compressed. Text, fonts and drawings are left exactly as they are, so they stay sharp and searchable.
