Why there's no upload step
300KB limits appear on banking portals, admission forms, and document-verification systems. It's a comfortable budget for several scanned pages, so compression rarely needs to sacrifice readability — the tool searches image quality entirely in your browser until the file fits.
Is my document uploaded anywhere?+
No — compression runs locally in your browser.
Will my scan still be readable?+
At 300KB, almost always yes — this budget usually lands at a quality where text and stamps stay clear.
Will text stay selectable?+
No — pages are rasterized to hit the exact target. Portals validate file size, not the text layer.
My PDF is already under 300KB — do I need this?+
No. Check the file's size first; if it already fits, upload it as-is.
