Frequently asked questions
Why is the text no longer selectable?
To cut the size significantly, each page is recompressed as an image. Keep the original if you need to copy text.
Why didn't my PDF get smaller?
It was already optimized, so the tool gives you back the original file rather than a heavier version.
Why does my PDF barely shrink?
A text-only PDF is already light; compression mainly acts on images.
Does text stay selectable?
Yes, text and links are preserved.
Is this tool really free?
Yes, 100% free, with no sign-up, no watermark and no usage limit.
Are my files safe?
Yes. Processing happens directly in your browser: your files are never uploaded to a server or stored.
